Hi,

I've been reading the threads, and couldn't find anything specific on a ME5, mostly me7 and some me3.

Anyways, has anyone successfully tuned an me5 557P? I also have another ECU that's chipped, can I just pull that chip and re-write it?

Main thing I want to do is remove rev-limit. Misc stuff is set base timing/fuel, adjust start up enrich. Then use my piggy to tune live.

It would be nice for educational reasons, to post these read-outs over here, if possible.

If i'm correct that ecu is very similar to the euro M3.8.3 (flashrom-chip inside) so as of tuneability that should be not a big problem.

Writing these ecu's chip can be done over obd if wiringloom is equipped with 1 extra lead to pin 43 of the ecu. And if the ecu has a flashrom.
Reading, sadly not. That stays a solder-job. Untill someone finds a way how to read it via obd.

Removing the revlimiter may be a bit harsh. Why would you like to do that ? There are rpm-limits to the 20v head's valvetrain...

Greetings,

PvL

Pin 43 would only need a 12v source right?

I did find an ME5 file here, could I just modify and write that?

Here's the file:
http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=725.0;attach=839 (http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=725.0;attach=839)


How exactly is rev-limit removed? From what I know rev-limit is indirectly computed, not sure what parameters.

As to why rev-limit: head is somewhat built (valves and springs), need to raise rev-limit when I install cams. Current is 7300rpm, after removing rev-limit, gona use piggyback to set new limit to 8-8500rpm

Looks like the file I got here labeled me5 is a me3.8.2. as per 0BF00 notes.  :(

Why you will use such ting as rev limiter of file you post is just there , sitting and waiting for you :)
Limiter start at adress 7DF0 6x5 table , factor 40

Greetings ,

Vency

Thanks. Sorry for the noob questions. I'm still figuring this out, my first time seeing hex code today.

With the file attached above, This is what 7DF0 has

AA A3 A3 A4 AA AA C8 C8 C8 C8 C8 C8 AA A5 A6 A6

So AA =  170 x 40 = 6800rpm correct?

So if I change AA to C8, I should have an 8000rpm redline?

Where can I see the fuel and ignition maps to check if there's any fuel or timing in that part.

It would be better for discussionpurposes to post the file you're working on, don't you think?

Or at least give us the bosch hardware/softwarenumbers that are in the file....

There is a reasonably fully documented .ols-projectfile of M3.8.2 over here on nefmoto. Tho in german:

http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=139.0;attach=362

This can be used to adress the maps needed to be modified.

PvL

Filename says its a ME5, but 0BF00 says its a 3.82

Here's the file
http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=725.0;attach=839 (http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=725.0;attach=839)

Do you have a stock ME5 file I can use?  :) - Been trying to find one for a couple of hours (google / nefmoto / chiptuners)

Here you have some homework-stuff ;)

Thank you very very much.  ;D

Hopefully I don't brick my ECU lol.

@PVL

1. I'm using Winols, is that ok? or should I use another program?
 
2. Are the files you sent, Stock Files that I can just upload to my ECU to basically reset it? (I ask because there were some differences between your files and the file I got from here, like 7DF0 was "0" and there were no labels.
 
3. How can I identify X and Y-Axis? - In most screen shots, I see labels (in German).

4. Does the ECU just use the last value if ever it goes out of MAP. (ie. if fuel map only goes to 6800rpm and inj duty at that point is 80% it will simply stay at 80% even at 8000rpm)


PS: I'm using your me3 excel file for the labels.  ;D

Re: rev-limiter.

Using the 8D0907557P - D06 file: When I check 7df0, it's a 1x1 table. - It has a value of 75

The only 6x5 table I see is 0B13B in the  8D0907557P - D06 file.

" I'm using Winols, is that ok? or should I use another program?" -> Thats o.k. Most professional tuners use it also... But you are free to choose
the program you want. What suits you the best.

" Are the files you sent, Stock Files " -> Yes, they are !

" that I can just upload to my ECU to basically reset it? " -> If you have a matching ecuhardwarenumber (028x number) , then yes. (557P - M5.92)

"(I ask because there were some differences between your files and the file I got from here, like 7DF0 was "0" and there were no labels." -> POST your file please
so we can have a look !!!

"How can I identify X and Y-Axis? - In most screen shots, I see labels (in German)" screenshots added by me. Thas not too complicated, i think ?

"Does the ECU just use the last value if ever it goes out of MAP. (ie. if fuel map only goes to 6800rpm and inj duty at that point is 80% it will simply stay at 80% even at 8000rpm)" -> AFAIK yes. It uses the last known mapvalue (most ecu's do, like Digifant) So fuelling is not map-controlled after that value !!!!! (on WOT)

"(PS: I'm using your me3 excel file for the labels.  Grin)"  -> thank you :)  It's all made to give more insight-info when beginning with this stuff. Hope it helps !

The .OLS-file posted/referred isn't a M5.92. I referred too. Thanks to Clemens, who obviously doesn't know what he is busy with... Or drank too much schnaps.
But it doesn't matter that much. It's excellent for getting to know the structure and finding the maps.

Greetings,

PvL

 
I'm only using the files you posted (specifically the D06 file) and the ME3 file that was labeled ME5 (Clemens). Your right, the Clemens file was still very helpful, Google Translate FTW.

Using your D06 file, how exactly do I set a higher rev-limit? 7DF0 looks different from your D06 file and the Clemens file.

Using D06 - "0898B" What is the X-Axis? And how do the values in the tables translate to degrees - Which I believe to be a timing Table and I think is the same table as your screenshot, just with the X and Y axis swapped.

Just the studied the maps more. The 3.8 and 5.9 looks like the addresses are in completely different locations.

Anyways, a'm I doing this correctly? I just look for the descriptors (rpm - A2 and load - A4), then figure out what the map is for?

Looks like I can use a 3.8 file on my 5.9 ecu. - Read a post of VR6 user using a 3.8.1 map on his 5.9.2 ecu. Only problem was the IMMO was preventing the car from starting.

Has anyone else tried this? I'm leaning towards doing this because the 3.8.2 is a lot better documented.

AFAIK 5.9.2 ecu = non-vr6.

You shall mean M5.9.1. USA passat VR6.

What's the weblink to the thread, so we can have a look to the article, please.

Thanks,

PvL

@ ricekikr :

About RPM :

http://nefariousmotorsports.com/forum/index.php?topic=1400.0

Ask the one who last posted, and we'll all know how he figured it out if he's so helpfull to tell us..

3.8 > 5.9
Couldn't find the link. Anyways he just mentioned that he used a different file and it didn't start because of immo. Nothing real specific. And yeah it was for a VR6.

RPM: I just PM'd him. Hope he replies and hopefully he was successful.  ;D

A question about the car : is the car originally equipped with the 1.8T engine ?

Ifnow, ther might be another way to manipulate the revlimiter. But i must first look further into this. This ain't simple.
There's no direct max-rev-limiter in me3.8 it seems. It's calculated differently i get the feeling. More R&D is needed.

The only thing i found is, when the speedsignal is not available (conversion into another car without abs-canbus communication)
or when the signal isn't correct. I've added a screenshot of this failsafe-rev-limiter. The Motronic.ws website gave me some insight
how they calculate revs. 10.200rpm should be max revs this box is good for.

It would be really nice, if other members could chime-in and give us a hint...  All help welcome/appreciated !!!

Thanks,

PvL

743A = Speed Quantization = AA = 6800

Looks promising.

Side question: My other ecu is socketed, can I just put in a blank 256k eprom and write the program using OBD or will i need to bench it first?

And is the Clemens file still completely stock? Would you mind posting a completely stock ME3.8.3 file?

===================================================
Long story

It's still a 1.8t engine. I just quoted the VR6 guy, because he was able to go 5.9 to 3.8 (but wasn't able to start it because of IMMO).

I'm not sure what you mean by speedsignal? (rpm or vehicle speed?)

If its Vehicle Speed Sensor (VSS), a few years back, I cut my ECU VSS wire (to remove speed limit, max was 130mph), with the stock ecu the rev-limit mysteriously went away for a while (ie. I could rev past 8000), not sure how long it was gone, because I used my piggy to set rev-limit at 6500rpm (engine was still stock then). I'm not sure if it's because the crank/cam/maf signal is being altered by the piggyback. After engine rebuild, I tried raising rev limit, but it would only go to 6500-6800rpm, tried trimming down the WOT MAF voltage (WOT MAF voltage looks like it going slightly downhill at higher RPMs), it would rev to 7300rpm. But on very RARE occasions it would still revlimit to around 6500-6800. Weird thing is this ECU is supposedly stock (I bought it used a few years ago). So even the 7300rpm isn't right. I wonder if the data if corrupt of something. Currently using it and it works perfectly @30psi/7300rpm.


My other ECU (chipped/socketed) has always had a 6500rpm redline, irregardless of what I did. Another weird thing is this ECU has always had a checksum CEL but never had a problem starting the car. And it also resets LTFT and STFT every time the engine is shut off, might be coded that way.

Both are ecu's are ME5.9.2 (557P). One stock, one chipped.

Engine / ECU specs:
1.8t AEB manual quattro (rods/valves/valvesprings)
557P
AEM Fic piggyback
Siemens 870cc
Mafless - MAF is still plugged in, but not in airflow.
PTE5857 @30psi - stock ECU + piggy + 93meth

"Side question: My other ecu is socketed, can I just put in a blank 256k eprom and write the program using OBD" -> Eproms where used in M3.8.2. We now have
OBD-programmable FLASHROMS inside (in the M3.8.3 and M5.92) VERY handy !!!!.

" or will i need to bench it first?" -> You can optionally benchflash it. For example with a mpps interface. Works great. 3mins and the job is done.

"And is the Clemens file still completely stock? Would you mind posting a completely stock ME3.8.3 file?" To my knowledge, all posted files are non-tuned, original files.
You want only the binary-file, and not the .ols-projectfile you mean ? Winols FULL supports the export-function, and you can export it back to a plain .BIN file, without
the labels. Time to wonder-around a bit in winols ;) The DEMO is restricted in only LOADING files. NOT saveing !!!!  Thats disabled.

That piggyback-crap can be thrown into the bin. I don't like it, and if you can really program, it should never be needed in the first place. Only if the original ecu cannot do extra tasks which are vital, then it may be a solution. Then one may use such a crude way of interveining/manipulating a original setup.  It's like the TDI-tuningboxes. They work. And there are a lot of differences between them. Needed ? No.

Would like to see some pics of that socketed ecu inside. What tune is it ? I bet, it's a crypted one.

About adresses of maps...  When a specific software-version is compiled, the maps usually are offset SLIGHTLY, compared to different ecu of the same generation. It has to do with several things. In Winols, you can link/lock 2 binary-files to eachother and slightly offset 1 to the other, so the maps are compareable and also the details of the maps can be copied into the other binary (.ols project on winols-full). That way you can document a binary from scratch and quickly see where all important maps are.
This counts for maps and constants. You need to get a bit of feeling with it, and it will be possible to get a 90-95% documented file out of it. I did this with a Golf 1.8T 1998 AGU ecu (06A906018R - D03). Picked the M3.8.2 pre-labeled file, and looked-up the constants and maps, and copied those.

http://nefariousmotorsports.com/forum/index.php?topic=1400.msg13370#msg13370

I've included the stock binary of that .ols project in this post. That should properly help
you out with the M5.92 as they are nearly the same. Only maps shall be offsetted SLIGHTLY. Thats
up to you to adjust, copy mapdetails, and create yourselfe a .ols projectfile nearly completely documented. Piggyback -> trashcan/ebay.
There are physical limitations to this ecu, but they can be overcome via larger mafhousings and bigger injectors.

The CEL-on-situation shall be on the tuned file i presume ? typiccal checksum-problems due to tuners who don't have the right tools or knowledge of this ecu.
This also happens on ME7 alot in the beginning, when just released.


-> Mafless - MAF is still plugged in, but not in airflow. This system (M3.8.3/M5.92) is based around maf-input. Sorry but this is just not the way to do it right to
    get full benefit of the ecu itselfe. It's a compromised situation in my opinion. A Hack. Not a tune.

Why not take a better/newer ecu that has way more capabilities for tuning ? ME7 can run big turbo's right out of the box. This one has too much limitations.

300 bhp is no problem. Above this, one needs to totally know the program to get a big turbo config running like that PTE5857, without using fooling-devices (piggyback
stuff).
 
"has always had a 6500rpm redline" -> coded into the ecu's software. By upping the Revlimit you scale-down the resolution of the maps..... So they need to be completely rewritten for accurate function and correct max power. This is with nearly ALL ecu's.

Thanks again for the help and the file  ;D - So I still need to offset it to make it work, I thought I could simply write the 3.8file to 5.9ecu and it'd work. If that's the case I'll just offset the 5.9 and learn what it's for.

Time to read up on Winols - Thanks for the tip on locking two binary files. I wonder if it can also lock the 1x1 maps.

---------------------

Piggyback - It was the cheapest option I had a couple years ago, before learning of Nefmoto. And I never thought I would even slightly understand HEX (I don't have a computer programming background). Didn't know that there was this much support (easier learning).

I'll still be using the Piggy for ease of use. Nothing beats live tuning and AFR logging. But yeah, I totally agree the piggyback is a bandaid tune. Definitely better to tune via stock ECU. But then again, I've been using this piggy for 2years already so far so good.

Mafless - I just like tuning with a psi scale instead of volts.

Winols Demo - Can't I get away with editing via Winols then just use HexEdit to make the bin file?

ME7 - I thought about this before building the car, mainly because of MAESTRO 7 (me7 tuning suite), But I'd have to rewire the whole car. (engine harness, replace instrument cluster and instrument cluster harness, various sensors, DBW throttle/pedal, etc etc). Basically too much work and money.

300bhp - Not sure how accurate the AEM FIC dyno calculator is (based on weight, rpm, gear ratio, front aero etc) - Max AWHP I got was 380awhp (roughly 470bhp) - 30psi / 93+meth / 1.8t.  When I was still using a 50trim it said I had around 270whp, but raced a 300whp (dynoed) (same car model) from a roll and we were neck and neck, so I guess it's somewhat accurate.

Socketed ECU - It was locally tuned by the previous owner, not sure what was used to tune it. Gona take pics as soon as I remember to bring home my torx set. Keep forgetting lol.
 
Rescaling the maps - Wasn't planning on doing that, because of piggy and last known value.

Hi.

"I thought I could simply write the 3.8file to 5.9ecu and it'd work" -> It ain't that simple. People really think too simple with swapping stuff. Like it's lego. Well it is, if you take some time to figure-out how stuff works. Then things begin to make sense, and you can see which parts are interchangeable without any influence.

You tell me for starters, why that US-A4-1.8T is running M5.92. And why we over here in Europe, have M3.8.2. on the same car ;)

The M3.8.3 file is of a Golf with 06A engine and same head as AEB (bigport). I would not recommend to use that on your car. The communication with other components, like ABS is specifically written for the 06A-platform in that file. Like yours is for the A4-platform written. All this, most people sem to forget....as OOPS...  i didn't know that ?
Yes a car is a complicated piece of hardware ! the manufacturer did it's best to adapt the latest technology availble to get the most out of it. In all aspects. Readup some volkswagen SSP's and you'll see how advanced they are :

http://www.volkspage.net/technik/ssp/index3_eng.php

ME7 is perfectly adaptable. No problemo. Immo-defeat the ecu, 1x enginebay wiringloom/ecu, 1 x potmeter-gaspedal and 1 x throttlebody, 1x maf. Add some fresh coilplugs and i think you're good to go. A few bits and bobs shall be needed extra, but basically, it's doable. Most are only afraid of it...  Getting hands dirty....

Winols : The demo is too crippled to work with. You cannot export. Only the full version can do this. But the software is very good to do some research with. The full version is needed for modifying and trying-out on your car.

Keep the M 5.92 for the moment. Try to read-out the current tune please. Would like to have a look at that. For what config is it tuned ?

I have a euro a4 1.8t using a USA M5.92 ecu. Maybe that's the reason for the funky rev-limit.

Would you happen to have a m3.8.2/3 that came from 97 a4 1.8t AEB?

Readout current ECU = I don't have an idea how I can do that lol. I don't have a fprom reader/writer. I'll just be using my ebay vagcom to write the files.



M7 = With my current setup, it's mostly cost for something that can be done at no extra cost / work. The only real benefit for me is that the ME7 can use much larger throttle bodies. I'm stuck with the AHA/vr6 TB, which gives me CEL because ECU can't do basic setting on it (but still idles just fine). My current setup is almost perfect, for me at least. Just need to adjust the cold compensate and change rev-limiter. But after I do that, I'd really like to set a base fuel map and ignition map to keep piggyback changes to a minimum.

But if this is gona be for a new project, ME7 would be great. More accurate control and less things to fail.

That should be for the 1997 model, this revision.

Thanks again  ;D

I'm trying to make an XDF file for ME5.9.2

Are the offsets in the ME3.1 manual applicable for ME3.8.2/3 / 5.9.2

Ignition Advance = Factor .75 Offset -22.5 = I assume this is in Degrees
Fuel correction start point is still 128. So X-128 = Y; is Y in %?


And how does one set the X and Y axis labels. It's like XDF is getting them from different parts of the file, eventhough I set start point to the same point as Winols. Right now I'm entering them manually. Just copying the Winols labels.

"Are the offsets in the ME3.1 manual applicable for ME3.8.2/3 / 5.9.2" -> use the M3.8.2 .ols file from Clemens.

You keep asking things that are in the .ols file.  Doubleclick a table (not a constant), in the window that opens,
rightclick a value in the table and choose preferences (text tab lower left corner active). There you have it.
The full monthy. All settings.

Good luck in tunerpro. Be sure to frequently safe your work. It's not that stable.... with bigger tables.

PvL

Ahh of course. I keep forgetting the Clemens file is all I need to make a 5.9.2 file readable. Sorry for the noobness  ;D

Edit: Are the "Potential Maps" that Winols finds real maps? I was comparing 16x16 maps. 3 were found by Winols for the 5.9.2, but none of them even look similar to the Clemens 16x16 maps, well except for one map found by Winols.

Spend some time in Winols, and you'll see it will pay-off the more you work with it.

Most adresses are offsetted of nearly all maps, so you need to re-align your m5.8.2 bin against the .ols defined one
constantly, but it is VERY doable. then the mapdetection and mapcopy-functions from binfile 1 to binfile 2 are a breeze
and help you quickly populate your m5.8.2 original file. Most values in the maptables and constants are 1:1 you will notice.
Very handy to quickly produce a specific .ols project of a specific software-version.

Most people call this a Damos, but it isn't a Damos. A Damos is something different. And rare. Hard to find. It's something
car-ecu-calibrators use in combination with advanced logdevices. Sort of Alpha-based code of the initial program. The
binary, is the result of the calibrator's work after compiling it. So it's ready for bosch to preload into the ecu that they
send-off to a manufacturer.

I hope to contribute at some point to this thread for "educational" purposes. I have an older 557P Box with a tune on it. I have no problem de-soldering the chip, however I am not in a position to purchase a programmer for 1 chip as of right now. Is there any place around Baltimore City, MD that anyone knows where I could take the chip to be read? Or even better Bel Air, MD? I know people used to take chips to T.V./VCR repair shops when I was younger, but I think those days are long gone :-\. I'm just not aware of any companies that use programmers?

@ rob.mwpropane :

Great proposal ! Only the programmer/chipadapter is essential to read it out. And not alot offer their services online in your neighbourhood as of this sadly :(

I was thinking...  Do you have a M7.5 or M7.1  flashrom-socketed ecu laying around ? If yes, this might be the way to abuse it :

With the nefmoto software or Galletto or MPPS or other bootmode-capable usb-reader, under bootmode, read-out the content via the M7.x ecu of the other
flashrom ?  I know this is a very crude method, but this may very well work ! ?

Don't do this right away, as i need to see pin-compatibility between the 200 400 and 800 chip.  It was merely thinking up out loud... But perhaps a unorthodox
solution to get flashroms readed-out ;)

If another helpfull guy in rob's neighbourhood can assist with a real programmer, we'd also would be happy. Do chime-in guys, with thoughts and ideas !

PvL

I never thought of that. What a great idea! In fact I do have a ME7.5 and a 557P both here along with all the soldering capabilities in one drawer. I have galletto clone, and am halfway through a bench flash set up/build.

Question; I downloaded galletto program from this site, should it just pick up the correct driver when I plug in the cable/ECU automatically?

**Just for the record, I'm not a fan of posting company tunes and taking professionals business, but at this point the tune really is ancient. It would be great for people to learn from. Hell, I would like to see what they did myself.

Hi,

Thinking 'out of the box' sometimes helps alot ;)

Emm, i was thinking. Galletto does a check perhaps, which minimon doesn't  (also capable of doing bootmode-reads)

I've added a screenshot of my software with the correct setting and a red box what should be instantly pressed.

But first, you should take your time, and finish the benchflash-harness. I already have that work done ;)

The idea about this way, is purely theoretical, but perhaps we can make it work in real-life to overcome the readout-
issue when we don't have a programmer laying around. It would be smashing, if it worked :)

And ofcourse, all stuff would be purely for education purposes. Thats what this site is also about, if i'm correct.

"I downloaded galletto program from this site, should it just pick up the correct driver when I plug in the cable/ECU automatically?" ->
direct windows to the folder where the galletto software is in, and there should be a Driverfolder inside that with the
right "ftd2xx.inf" file in it. thats the one to select, and then your install will be correct as of the driver.

The main software can be started right-away. (in my case NEW_SERIAL.exe)

I run winXP-SP3 btw. All other O.S'ses should make sure, they run the app as ADMIN !!!

Now hopefully my hack can be made working :)  I can also try this over here, but need to firstly solder-in a meritek chipsocket, and
desolder the 2 flashroms...

First some extra homework, if i didn't have overlooked something.... Theoretically, putting the processor into bootmode would give the
program access to read and write the flashrom without any moaning.

Getting back on this subject asap.

Greetings,

Pvl

I think I found the rev limiter on the 5.9 files.

D02 file - 6D9C-6D9D and 23784-23785

A4 file - 1BAA0-1BAA1

Wrong answer...
6D9C (8-bit) = 250rpm - RMP hysteresis when tranny guard active
6D9D (8-bit) = 1 sec - time for automatic tranny converter guard

Another addresses is part of exe-code...

Oh crap  :(

Any tips on where to find the rev-limiter? I just searched for 6500, and those were the only two spots with that value. There wasn't a 6800 value.


*file I'm interested in, posted below

Is 743A for the 3.8.2 (clemens file) = speed limit on velocity error detection signal  = 6800 = NMAX = Rev limiter? - It's the only address labeled NMAX that has an RPM value.

If it is, I think I found the rev-limiter for the 5.9.2

And how exactly does ME3.8/5.9 set rev-limit? - I've been getting mixed info, from reading and directly from guys that seem to be in the know (is it calculated or is there a set RPM like in every other type of ECU)

EDIT: 743A is the same address that PVL posted on page 2.

9563 - TVUB - Voltage Correction (3.8.2 Clemens file)

As per S4 tuning manual - TVUB should be Voltage Correction for Injectors.

How come the voltage scale is 2.04 - 1.97 - 2.04 - 1.97 - 2.04. Shouldn't it be rising or falling not back and forth?

And how do I set the X/Y axis in tuner pro, it looks all messed up. I skip the Descriptor and Map Size Identifier, then put in the Start address as the next address besides the Map Size identifier. It looks no where near what WinOls is displaying (factor and offset applied)

This might happen to be an old thread, but where do I find the ME3.1 manual? You can't really search for it, as it comes up with anyhing that contains "ME3".

Thanks

You can find a really nice M3.1 tuning guide with lots of info about it here --> http://www.ecuconnections.com/forum/viewtopic.php?t=867&sid=214bb026236cce504b76ab1af6f3b52e (http://www.ecuconnections.com/forum/viewtopic.php?t=867&sid=214bb026236cce504b76ab1af6f3b52e)

Been reading this thread, because I am interested in tuning the 557P for my 99 Passat with the AEB. I actually have a spare ECU for it (bought from a member on PassatWorld for $20).

I have a bench harness made, and have successfully read it using VCDS Lite. I also have a MPPS v13 cable, but from there.. I am not sure where I am going.

I know the ECU is a 8D0907557P, which should be a ME5.9.2. I have seen some differences in versions... D02, D03, D04, etc etc... Mine is a D04 (according to the sticker on the front).

I downloaded PVL's D04 file, and open in in WinOLS, and it asks me info about the vehicle. I put it in, but I don't get the list of "toggles" on the left.

I think I need a crash course in WinOLS....

My goal is to be able to do some minor things like rear O2 delete, mild tuning for exhaust mods, etc. Nothing major. I have this spare ECU to practice with, so if I do kill it, I still have the original ECU to put back in the car to run it.
