NefMoto

well disaster struck. my read flash, mods with tunerpro and checksums via me7correction all went smooth. Go to run my write flash and my computer goes bluescreen. Laptop is toast wont even start back up. So I purchased a new one. But I'm stuck with a bricked ecu 8b0 907 551m and no galetto? cable. Ive already invested so much time and effort into this project and could really use some help on the current correct way to effectively rescue my bricked ecu... Anyone wanna point me in the right direction please?

Try logging into the ecu as it is and see if you can get a flashing session started. If that does not work, you'll have to put it into bootmode. You'll need software/hardware that is able to write in bootmode if that's the case.

Where are you located?

Eugene Oregon. North Eugene area.

Is this maybe the answer to my problems? Can it rescue a bricked e.c.u via boot mode write?



ME7_95040 is a console application that allows to program ME7 ecu's EEPROM.
It has been tested successfully on ME7.1 and 7.5 ecus.
Tool works with a dumb kline cable, either usb or serial.

For usage instructions, in a command line window run 'me7_95040 --help', it will display the program options with some examples.

Also I'm having trouble getting windows 10 to download nefmoto because 3.5whatever wont install. Any tips? If I cant get this computer connected ill have to get windows 7 like my old laptop I loved. is there a setting I need to change? lost with windows 10

No.

The eeprom is a different device from the flash.

2 options to get your car running straight off. You can use a regular kkl cable with galletto but you need to patch the EPROM in the cable with the serial number that matches the serial number in the program. Then boot mode flash and you're on your way.
Other option is buy another apb ecu, it doesn't have to be a s4 or even a manual ecu. Auto a6 ecu are the cheapest and are easily cross flashable. If you use the m box file you won't need to immo off anything or flash the EEPROM. M box is non immo so it will ignore the kill command from the EEPROM. Good luck

Giggity, ill let ya know how it goes

So I'm having a lot of trouble figuring out the drivers for windows 10 and gallato. Also I don't know how to change or locate either epom... please help lol

So I took apart my E.C.U. casing to get into boot mode and found a giac socket installed. Previous owner failed to mention  ??? ??? So how to i go about fixing my failed flash now? giac socket chip changes the layout of the ecu... Ive contacted giac and am awaiting a response

Remove all that jazz, and solder in a fresh flash chip.

Or get another ecu as noted above.  Also use an xp vm if you are having driver compatibility issues.

what is and where do i find an xp vm? thanks btw. Im just gonna get a new chip from an a6. $85 at the yard and flash it.

Windows XP Virtual Machine

and dont give the yard $85 for a old used chip when you can buy a brand spanking new one with faster access times for $1.

Does this make a difference?

no

It's nano seconds faster nothing you'll ever notice, but it tickles my "faster is better" bone  :P
Just emphasizing that new and faster can be gotten for a fraction of the $85 the wreckers would charge for an old used chip :)

After reading that any 7.1 ecu is compatible with m box I went and pulled one out of an a6 and found the connectors don't work. So I got frustrated and ordered an m box off of ebay. It will be here on Thursday at which time I plan to flash a stage 1 bin ive been tinkering with on tunerpro. Ill try to attatch it and see if the higher ups approve? lol. I also ordered some high temp automotive paint and will include a photo of my plans. Well just discovered its not easy to upload things at a first glance. give me a minute.

ok 3rd try.

My paint design with wing and the tune with adjusted timing, air to fuel ratio and desired boost curve. and checked/corrected.

Trying to figure out visualme7logger.exe so I can fine tune my stage 1 set-up, but Im failing. Have ft232r cable. Connected to ecu through nefmoto easily. Cant seem to load any files other than examples that were included. Ive grouped the appropriate folders I believe. Maybe someone will give me the rundown? I'm running windows 10 if that matters...

Also,

It happens nomatter what I seem to do.

Try unplugging the cluster fuse or disconnecting the cluster.

Also, does it work on the bench?

I just have a cheap blue cable. No fancy bench flashers yet. Still cant get nefmoto to read the whole file.

honestly, you shouldn't be having that much trouble with a 2001.5 s4, the kline is generally rock solid.

Might be your cable.

Went backto old laptop. 100% first try. Now im wondering how to get my xdf to show properly in tunerpro. everything says 3 or 30 as a value. also i noticed a difference in component numbers and cant seem to find the difference between g0001 ("new" Unknown 8d0907551 box flashed to m-box) and s0002 (original m box). help plz?

A6 went 7.1.1 in 2003 (U.S.) with the BEL; different connector.  (Well, keyed differently.)

it was a 2002

Im wondering what i did wrong? everything looked and checked out right...to me at least. didnt even write 1% before it bricked. Anyone wanna check my files and tell me what im doing wrong now? Ive attached my original m box giac-socket bin. The M box bin from the current ecu. The modded flash bin that i used the giac bin to compare with, checksumed. And the .xdf file that I used. Ive spent so much time trying to make this work that it is negatively impacting my life. lol

Is there a write protection/encryption chip on the socket?

Dont ask me man... lol. Im just some stoner from Oregon who likes to work on his car and go fast. All of the sudden im the most talented computer guy in my family. ha. Not saying much obviously. If anyone knows How to fix it id sell/trade it. It's a sweet chip if you get it working. Should have left it alone. I'm in the middle of piecing together a benchflash setup to run galleto gellato, whetever, or kwp2000 for my current bricked 8d0907551?Box from ebay THIS IS THE RAM PROGRAM BIATCH. I know, im dumb. But ill make it work. To better answer you, I was able to read it. I think the values matched up with the bin and xdf through tunerpro. Use it as a compare bin for 8d0907551m 0002. Says the guy whos bricked 2 times so far this month.

Can you upload som pictures of the ECU PCB and the GIAC socket? :)

Yeah, it kinda sucks you in. I actually just started out wanting to get my ECU back to stock because of reliability and economy, and the "tune" that was on it when I bought it was laughably bad.
And now I have ended up using all my spare time reading anything I can about engine management.
And using my weekends tweaking and logging :P
I have always worked with car, but only the mechanical aspect. Now I'm messing with all the electronics too, and as always when you fiddle with stuff that's really not meant to be fiddled with, there will be some casualties along the way :)

Yeah i will tomorrow.

Im in the middle of trying to figure out the drivers for galleto. ft8u2xx?? i cant seem to find the rosstech vcp on my computer which is now a mess of folders.
ive got my ecu exposed. several failed attempts to bootmode. This is the final straw until i make a harness for bench flashing because the failure rate is ridiculous. And i hurt from sitting hunched over on my laptop in my car all day everyday for weeks now trying to piece this stuff together.

I read somewhere that too much voltage could be causing my issue. I fixed my ftdi ft232rl uart ebay cable (that read with nefmoto) serial number to the "public" gellato account using Mprog. Grounding pin 24 to the negative battery terminal (second one in from the back opposite of the dot on 800bb chip) for 3-5 seconds after connecting battery/charger then turning key to on. Then pressing read ecu on a plugged in laptop (windows 7) and getting an opening port impossible message. Any advice? I'm sorry but Im asking for some guidance. Im frustrated. and I need to be able to drive and pick up chicks..

Now it wont respond in either mode

Are you reading/writing on a bench setup or through the OBD port?

obd in car

If you're having so much trouble reading and writing, take the ECU out of the car and use a bench setup.
They're not that difficult to make and cost nearly nothing.
You just need a 12v power supply(an old PC power supply is more than enough), some wire and some terminators :)

Or, take the ecu out, and snap a picture of the board like you said you would. This thread is a waste without knowing what's on the board. If there's anything other than the stock ic in there, you won't get anywhere. Ever.

I'm working on it today. I'll report back if i have issues, thanks

Look bud, not trying to be a dick or cause an issue but ive got enough problems right now And not being able to take a photo of something i accurately described is at the bottom of my list of things to do. I apologize if that causes you frustration. The Giac socket chipped ecu is old news anyways. Im either trying to bench flash my 8d0907551?(Had M flashed over whatever was in it before) me7.1 0001 0-261-207-004 or I'm buying a new ecu to try again but directly from the bench as in car seems impossible for me to accomplish right now. We will see. and i will accurately and thoroughly explain it in proper english for all to see and use as a guide because ive hit just about every road block and difficulty trying to make this all come together. I'll do a full write up when finished.

Nobody needs a writeup. Here are some facts to hopefully help you.

1. If you can't comm with the ecu, flashing a stock file in bootmode is your only solution.
2. If you're trying to flash what you read from the old GIAC ecu, it will never boot, or start. Maybe both. Don't bother trying.
3. All B5 S4 ecu's are the same hardware-wise, so you can flash whatever file fits your year/MAF/trans type.
4. There are lots of people on this board that can help you get this ecu up. Maybe sending it to someone is a good solution at this point. Think of all the time you're spending.
5. Your verbal description of "giac socketed" is nowhere near accurate enough. Kasper asked you a few times to post a pic of the board, and at no point did you answer him by saying you're not working with that ecu anymore.

Goodluck.

I posted that earlier in the thread. Ive not used my giac bin for anything but a reference on tunerpro. Im assuming a socket chip is an extra board/chips soldered where the original 800 chip was. Its not just a flashed chip.

Bottom line is for some reason, you're able to post pics of an S4 with graphics and a huge wing, but not remove 4 screws and take a picture to satisfy the people in this thread that are trying to help.

is There a clear picture as to building a bench setup for kkl cable?

I have wires, a fresh ebay kkl and a 12 volt 3 amp power supply and a bricked 8d0907551(?box)-0261207004-0001.

I dont know why i cant post the photo man. chill out about it. Ill try again

here we go

Holy shit that looks old. Has multi-map as well. Haven't seen one with a buzzer yet, either. Thanks.

I take that back. The black wire looks like an ant. Does GIAC have wireless map switching?

http://www.giacusa.com/news_and_media/display_news.php?id=140

I vaguely remember coming across that and wondering as well. Just wishing po had told me about the chip...

So about that bench flash setup, anyone got a link as to how to setup my bench kit using KKL? I have wires and power supply.

You want it?

Yes.

Also, why not just use the harness that's in the car? You don't need to build a bench flash harness. Put the battery on a charger, and bootmode it in the car.

Ive tried many ways. I want to try bench but cant seem to find schematics now.

First page :)

So bench harness seems to work. everything lights up and nothing catches fire. still no response from ecu. wondering if my problem is galletto... The cable serial number should be entered as 47514789 with mprog on my cable correct? And if so, why cant i seem to get it to stick? always goes back to original numbers in serial number slot... Ive triedconnecting in bootmode to ecu on nefmoto flasher as well. no sign of life.

Nefmoto software isn't ready for bootmode yet. As for the serial number, you'll need to save/burn that to the cable through mprog.  There was a thread made by Daz on doing exactly this, walks you through the whole process. Very easy.

I have no idea why nobody seems to want to read what I wrote:

Alternately, you can hex edit the galletto executable

So, I can read and write the giac m box ecu but no starting the car. Gonna see what i can do. Probably nothing. The other newer ecu will not connect at all. Bench read on the giac only took 4 minutes. So my bench setup is working. I dont know if im getting the other ecu into boot mode. It seems unresponsive. Thinking im gonna get yet another ecu and try benching it from now on. In car was impossible for me for some reason. It reads the giac everytime as well so im thinking i wont have the writing failure that bricked me as long as im on the bench.

I do!

Ive been through all of that. Wasnt trying to use it for that either. Clearly stated itried using mprog to alter the cable sn already. It doesnt seem to change like i said.
