Title: Bosch ME 7.5.10 - Memory 29F400BB doubled and writing through OBD Post by: petrzmax on June 15, 2020, 11:20:27 AM Hello my friends!
I want to remove the EGR valve from the Golf 4 1.4 16V. Using the USB VAG KKL interface and the nefmoto ecu flasher program, I succesfully read ECU memory. The problem is that the program allowed me to read ecu only using the 29F800 memory layout. Similiar problem which I have found here: http://nefariousmotorsports.com/forum/index.php?topic=711.0 My ecu code: 036906032G Readed file had 1 MB, but it could not be edited. The ECU has for sure 29F400BB so according to the information I found in the topic above, I divided file in half and the two created files are identical. They can be edited correctly and the checksum is ok. I don't have problem with editing the file, but as it's my first chiptuning job and as you saw there was something strange problem about reading I would like to make sure before I will brick my ecu. I will point out that I would like to avoid taking ecu out from the car. Here are my questions: 1. If I was able to read the ecu via nefmoto without any problems, can I also write modified file through obd without problems? 2. Should I try to force nefmoto to use 29F400BB memory layout when writing, or should I double the modified file and write it with the same memory layout I was able to read it? If you have any tips for these operations let me know;) Thank you in advance for any help!

I was sure that I have 29F400BB inside, so I ignored the warning and read the ecu successfully. I'm going to try writing soon, and I hope it will be fine :D |
