edc16u31 ecu dead after writting with galletto 1260 clone

[honingkoning]

Guys i had a transporter 2008 for tuning, i read ori file with galletto, modify and write back.
After writting ecu is dead.
I put bdm file from other ecu with same nr's but still ecu is dead.

I bought second hand ecu from yunkyard make immo off, put ecu in car all ok.

With my stupid head i was thinking first time was just bad luck and did the same thing with the second ecu and now second ecu is also dead.

I tried to connect to ecu on table (by connector) no connection possible i get error silentkey lectura (in ecu pin 3,5,6 and 18 pos/ pin is ground/pin 72 is kline/pin 89 is can high/pin 66 is can low)

On galletto obd connector i put on pin 1&2 gnd/pin 5 can low/pin 6 can high and pin 7 kline

With bdm i can connect and read flash,eep, and cpu.

What is going on and what is causing this problem, i want to solve this ecu is very expensive.

Did someone ever met up with such strange thing?

Did you checksum the file OK?
Who did the tuned file?
Do you have original read by OBD and the BDM backup from the second ECU at all?

[honingkoning]

Checksum is ok Checked by me and also galletto.

[motorsport]

1260 is galleto 1?

[honingkoning]

Yes it is galletto 1

[honingkoning]

Does someone know if its possible to write with xprog if yes what is pinout

[quattrotr]

Your tool is crap. Get some better ones.

[easytech]

EDC16U31 year 2008 is can-bus so reading is ok by K-line but not writing.
You can repair the BDM file with your Galeto reading.

[honingkoning]

File is good already Checked, also ori bdm file written back but Same result

[wiseman]

Galletto 1 is actually Good with VAG edc16 never had a prob, but there are a couple of sw versions about,

This version is good, You can tell the versions by the size of the EXE file.

[ominimicu]

all files are ok,it s not a file intergrity problem, he s got no comm via obd, nor directly to ecu connector.. but will read/write ok via bdm...

[wiseman]

211805This is the xprog to BDM Pinout for you

[bondiblu]

Is it even possible to program EDC16 via connector on the bench? I thought a can gateway is needed. However You should be able to ID it.

Maybe I'm wrong, but I've never been able to

[Faboka]

Same her mate. Can id and read on the bench via Obd but not write. But then I only have 11.8v powering the ecu. Not sure if more is needed.

[honingkoning]

I ended up with Other ecu.
Still qurius what causes this problem.

[miha99]

On the bench no chance without immo signal, you can try immo off eeprom and than bench flashing via K line.

[Faboka]

Thanks might it a go out of interest.

[honingkoning]

Ecu was immo off so should have worked.

I Will study this ecu and report for future refference maybe someone Will stuck with same problem.

Wbr.

[786mo]

But writing back with BDM didnt work?

[honingkoning]

No ecu still dead.

[morgano]

Maybe you select wrong ecu type, edc16U01 has 1Mb flash, and edc16U31 has 2Mb. meybe you read 1mb and try to write 1mb over a 2mb ecu thus corrupting it. Just a guess. ;)

[honingkoning]

I removed ecu and its written edc16 u31

[morgano]

Yes, and 16U31 is 2Mb flash. Are you sure you always choose in software EDC16U31 and not EDC16U1, and that the files you are working with are 2Mb?

[honingkoning]

Yes my friend i Checked and rechecked at least 10 times.

Wbr.

[Faboka]

I've been playing with a edc16u1.

Bdm read ok.
Galletto 1260 read fine on bench but unable to write. Same with mpps v12.

Carried out a immobiliser off and was able to write with both galletto and mpps. No issues with writing with the galletto. But this is a edc16u1 ecu.

[teapotsrus]

I think MPPS is a better tool for EDC16 than Galetto. I've written EDC16C9 and C39 hundreds of times and only bricked once. That was due to an error in the file rather than any real malfunction.

If you can upload the original partial read from Galetto or MPPS and the BDM read taken after the ECU corrupted, I should be able to splice them together in winOLS to restore the compelte original that you can write back with BDM. I've done this for a couple of EDC16C39s that fellow vectra-c owners have bricked and it worked well.

I've also had issues with some EDC16C9 and C39 refusing to write with MPPS and had to resort to BDM. Didn't realise it was an Immo problem. I have a previous customer who is coming back to me with hybrid turbo and will probably need to tweak and test the map a few times. Wasn't looking forward to the repetitive cycle of:
1. Remove bumper and ECU
2. Open ECU and BDM
3. Close ECU
4. Refit bumper and ECU
5. Test
6. Repeat from step 1...

I'd like to try clearing the immo on this ECU and see if it will write with MPPS. May I ask what software you use to disable immo and where I can get it?

Thanks!

[ominimicu]

its not immo mate...Its MPPS that sucks..read 2 checksum blocks out of 9. and deletes all 9 of them, but will only write 2...
Use BDM or another tool. FGtech 2 seems to work fine!

[teapotsrus]

Ah ok, i've got a g2 v52 on the way so hopefully that will solve my problem. thanks!
