Hi, I'll try to make as much sense as possible here, but sorry in advance if there will be some BS.
Anyway, I don't know if it is out of boredom or because maybe I haven't suffered enough in life I have started to tweak around with my wife's Beetle. It's a MY2000 New Beetle running an APH engine. So far it has got a T21 Frankenturbo, exhaust manifold, catless 3" exhaust, front mount custom intercooler with some extra cooling access in the bumper, Bosch green giant 440ccm injectors and a 70mm MAF, upgraded fuel pump. And a big brake kit, full poly bushes set and aluminium subframe bushes with Bilstein coilovers.
Like you see, total waste of time and money  ;D, but she loves driving it and she tells me a couple of times a week how she smoked someone at the lights or in a fast corner. Pretty sure the other person had no idea that they were racing her  ;D

Anyway, the ECU is somewhat set up, but just for daily use, the engine isn't being pushed hard at all as there isn't a proper Damos file found for this ECU, several people have checked already. So far my friend Frederick (he is also on this forum but i am unaware what his user is here) has setup the tune as well as he has been able to, doing it pretty much blind.
I'd like to push the engine with it's current upgrades close to what it can handle, to optimize all the upgrades, unfortunately it seems that can not be done with the APH ECU.
So guys, I am asking for your help. To which ECU should I swap to? What would be the easiest to get, which has a proper explination file available and would require the least amount of work done on the wiring - repining the ECU socket and so on.

I know many of you have experience with it and I am told there should be topics about it here, I have searched but haven't found good ones. It might also be because I really suck at searching for stuff, sorry about that.

If it seems like I am a total NOOB then don't worry, you are right. I don't know much about how stock ECU's work and how their tunes are done. But I do know cars and many aftermarket ECU's, my daily job is in depth vehicle electrical and diagnostic work with some aftermarket ECU dyno tunes, some Revo tunes and so on.

I will be very grateful for any info You can share with me. And if someone has a spare ECU suitable for this use then I would like to purchase it.

Current ECU details are PN 3B0907557R, BOSCH number 0261208003, ME7.5

I know a lot of this info is unnecessary, but you never know what small detail makes a difference.

(My next plans are to replace the TB for a slightly bigger one, also swap the intake manifold and to upgrade the intake cam. WHY? Why not. I want it to be a very fun city driving bug. I am not looking for high power, but anything to improve low end and midrage power. But these are just ideas and I haven't done indepth research yet how all these changes work together and/or if there are cheaper upgrades at these power levels.)


To anyone who has made it all through to this line here - thank you so much for giving me your time and being interested at least enough to read through all this. To any one willing to help, thank you very much  :)

Well that ecu part number is from a passat with the alt engine code...

You are right.
I've never checked. We did have a mishap once when rewriting the tune that the ECU got damage. I then sent it to an electronics shop in the hopes of them getting some info off the ECU. Maybe I got the wrong one back or the wrong cover on it. Or maybe someone already did something before me.
Cause when it fried I replaced the ECU with another one, just wrote the soft on it which they managed to get off it and disabled the immo.

Maybe the PN is then 06A906032 and BOSCH nr 0261206507.

These are the only other numbers I've taken down for myself  a long time ago.

(there's always something, never easy straight forward thing)

You didn’t mention doing rods in your list of upgrades. I would strongly urge you to do rods before pushing the turbo. I broke a rod with a very equivalent turbo on a “stock rod safe” tune. Drove that car for about 5,000 miles before it let go on me. And when it happened I was pulling out into traffic at maybe 1/2 throttle and 3,000 rpms. Do rods man, it’s not if they will break it’s when.

More on point to your questions....if memory serves me correctly APH is narrowband....with continued mods I think it would be worth your while to wideband conversion and switch to an AWP ecm. There are some really good definition files out there for the AWP ecms

Yes, that is true that I haven't done rods yet. I know it is a case of when not If.
But I am that sort of person where I like to do several things then. Not just rods, but why not stroke it also then, once doing that, should also Port the heads, bigger valves etc. You see how it is going. I think I would be happier If it blows up, then it needs doing  ;D
Anyway, for the moment the plan is to get it running on an ECU which can be tuned nicely. Altough it is currently driven daily and it drives good, I'd like it to be tuned properly and for it to drive without the current hickups. A proper ECU setup is needed anyway, so that's why I am looking into that right now.
Not at all that you have a bad suggestions or that I am not listening to it. I am, but right now I do not have money for more than research anyway, best case, I can afford the correct ECU setup and get it running a little nicer than currently.

AWP you say? Thank you very much for that info. Anything more you can share? Like, do you know the PN or Bosch number for this one, to make it very easy for me to find one and/or do you know would there be any wiring involved in this swap.

PS! My APH is wideband, yes it is, precat sensor is a typical 5wire wideband sensor.

Nice that its already wideband. I am currently running HS software on a LP part number ecm. If you have a boot mode setup that works you can get froggy with cross flashing to different part numbers. If it is not compatible worst I have personally experienced is a bricked ECU that I was able to flash again in Bootmode to restore it to the previous flash that worked. My bootmode setup, while not pretty does work. I ordered a galetto cable off walmart.com. Took an old dell desktop power supply out of a desktop for power and ground supply and then ECU connectors from the junkyard. Saved me 3 or 4 times now from stuff happening while flashing.

I have the chinese KESS and Ktag tools. The "accident" was completely human error. Trying to rush things quickly, was way too confident and got some wires mixed when connecting to the ECU. I usually triple check stuff myself   ;D
Anyway, shi* happens.
Sorry for the complete dullness now, but what's the difference on the HS soft compared to the LP one?

Had a better XDF :) My file is the 5120 community thread. Somewhere in the depths of this foruM I at one point had found someone that posted they had done the necessary ASM modifications to go 5120. I don’t know IDA so I took that file and reverted all Maps back to stock except the 5120 division stuff and posted it asking for someone smarter than me to confirm it was correct and it was....so get some rods and go E85 on 5120....car rips compared to 93

Now you lost me. Like I said, the internal logics of a stock ECU are not something I know. I need a bit more english from you to understand what you ment, sorry.
E85 unfortunately isn't sold in me current region. Best I can do IS add water/methanol injection later on.

Sorry, long story short the difference in HS vs LP/PL was simply the availability of a very well done definition file for tunerpro.

Also if you haven’t run across it yet Nyet’s tuning page is full of everything you need to learn the basics and then some of tuning your car yourself. https://s4wiki.com/wiki/Tuning

Ahhaa. Ok, got you. Thanks for that info. Altough I think I'd rather swap out the ECU just because I think it is a "safer" option for me. As I would keep the current running ECU somewhere oma drawers and would be able to always swap it back if it Ever needed for some reason. Also slightly scared of bricking it. Because my wife would hurt me a lot if I have to take her car off the road again for more than a day or two. So it's actually more self preservation tbh :D

Ok, that'svery handy to know, thank you. Will get into that once I have this ECU question answered.

I should probably sticky that here.

It is here though:

Thanks for that Nyet.
And thanks for even bringing that up Justinw2646

If you or yor frend have legal winols - full mappack ols project for your 0261206507 06A906032A

Cool, thank you gremlin. Will try to have a look at this. Awesome

Once justinvw2646  mentioned the AWP ECU I did a bit of googleing and came upon one forum thread where they discuss the different pinouts of the different ECUs and even have added pinout diagrams, I'll add it here, maybe someone else also needs it.

Seems pretty simple, would need to bridge connection from pin3 to pin21 and do something with the variable cam adjustment, either put a resistor there or rectify that issue in the software. Haven't gone deep into it yet as I have some other things to attend to today. But seems easy enough. Altough the fan control module J293 connection is still something I don't understand, it is connected to pin61 on the APH ECU but isn't mentioned anywhere in the AWP ECU, wonder if that can be just neglected or what?

Can you tell in short...
What do you want to do?

All 1.8T have same pinout. General there are 4 of kind 1.8T ecu
1. Some models till 2000 year 512 kb, narowband no ECM relay for powering 121
2. Still 512 kb, narowband but have ECM relay
3. 1kb ECU bootmode version 5.12 till about 2002-2003 year
4. 1 kb ECU bootmode version 6.12 from 2002-2003 till end of production 1.8T

1.8T 20V was produced until 2008 or so (CFMA). But yes that is good info.

OK, so, just for information purposes, my current ECU is 512kb and it is wideband.

What do I want to do? Well I'd like to setup my ECU properly so it can be finetuned, set up nicely without any current running hickups.
As the current ECU doesn't have a "description" file then the setup/tune has been done blindly. I'd like to properly tune this ECU if possible but for that a fitting "explination" file is required which I nor other have been able to find, even the searches through this forum haven't gotten me anything, till now. Hopefully what gremlin has posted is what I need.
Because I have till now had the impression that this ECU isn't tunable any further. So I started looking into other means of getting what I need and the next idea was to swap out the ECU.

So, in very short, I'd like to setup the car properly, by any reasonable means it takes, anyone willing to do this for me/with me is much appreciated and can contact me  :) but tilll then, I'll try to find out all I can. As always, my way of thinking might not be the correct way and that's why I am here on the forum to gather more information and maybe even change my way towards my goal.

IMHO you have information on all calbration maps of the original ECU.
This is more than enough to make a quality tuning.
To see what information is in the project that I posted, download the demo version of the winols program from the EVC website
This demo can open the project for viewing.
https://www.evc.de/ftp/winols/WinOLS_Testversion.EXE
Replacing the unit will entail incompatibility problems (for AT / air conditioner/airbag modules), which will need to be solved.
Also CAN signal matrix on cars 99-00 differs from matrix used for 01+ cars and this can add incompatibility with ABS-module.
Not the fact that the ecu swap will be easier and more convenient than just customizing your original ECU normally.

Pretty sure there are no 512kb wb me7.5's out there. unless you mean standalone wbo2 gauge,which is not the same. And swap ecu if its better for you, you will spend tons of time doing stuff on original , its not worth it specially when me7's are so cheap. ( still quite unsure what it is exactly you are tryna do  ;D )

gremlin I completely agree with you. If the information you shared works with my ECU then that's all I need and happy happy days.

The confusion might be because I asked about the ECU swap, but I only asked about this because I was lead to believe there is no info available for APH ECU and an ECU swap is my only way for tuning.
I myself have no idea how to use the winOLS, I have shared the provided info with my friend, hope he can help. I myself have no clue

I just want the car tuned for the hardware I am running and I was lead to believe previously that an APH ECU can't be properly tuned. Hopefully the info gremlin has shared helps out with this and an ECU swap is actually not required.

May you believe it or not, my ECU is 512kb and the stock precat sensor on the car is a wideband. No aftermarket sensor on the car.

The one who laughs last laughs well ... ;D
Learn the material part - APH ecu is unique ME7.5 512K  with WBO2!!

Wow my bad that is one unique ecu then, I get why you said it now, first time i've seen that.

And yeah like he said and since he posted the mappack , you can use test version of winols to basically do everything except save the bin, if you want you can make an XDF with the map adresses in TunerPro, then you can use it to save etc.
