Title: moates roadrunner on me7.1 no connection in vcds Post by: pizzaschnitzer on June 07, 2017, 09:09:06 AM Dear Guys
i bought a roadrunner guts kit and after a first defective unit and exchange from moates, ive a working unit. the unit works and verifies in tuner pro and emutility both. the file is changed if i change any part in the file with hex editor, it will be changed thrugh the emutility. BUT: the roadrunner is connected to an me7.1 from AJK engine (4b0907551F, 1024kb) and with his file in the emulator, the vcds does not answers (no connection to control unit-error after some attempts) if i change the ecu to a different one. 4z7907551S, N or some from an RS6, the connections works. i checked the soldering from the mount hub many times, every pin seems correct, the byteswap-board is mounted, no shorts are viewable on every connection pin. pin1 from roadrunner is on pin1 from the byteswap, pin1 from byteswap is on pin1 from the ecu 29f800FF slot. the error is the same with and without byteswap board. even with ecu on or of flashed emulator, the error is the same. the ecu worked before i unsoldered the flash memory. does anybody has still an idea? logically it must be on the connection, but... i bricked an ecu before on desoldering the wrong way, learned from it and made it precicely on any pin. can i test my connection port on the ecu in any way? mabe i solder the flashmemory back to the ecu. best regards with hearts for your help!!!

On my Roadrunner/ecu I run a wire from the ecu directly to a separate obd plug which I use soley for kline logging..

i now connected the roadrunner directly on the port, pushed the file through the winendian byteswapper and the VCDS connects properly and all functions ar working. can anybody tell me know how i can byteswap the xdf file for correct modification in the tuner pro. thank you very much!!!!

Title: Re: moates roadrunner on me7.1 no connection in vcds Post by: pizzaschnitzer on August 15, 2018, 01:33:48 PM today i got the rr working.
the me7.1.1 is 4z7907551S with 551N Data on it so far. the eeprom data is 95p08, not 95040, there was an death code in it. i managed it and the file needs to be endianed. actual 551s ecu roadrunner direct on it tuner pro (normal) file save checksum.bat (i made myself) winendian swap emutility for checking the file and uploading. the car runs on the modified ecu with or without usb connection like normal. last problem is: how to change the coding from allroad automatic (the regular 551s coding) to a6 mt6. Login? that i will try next. i changed krkte while running and view the lambdaregulation in vcds working. now i can change the parameter i want to. me7 logger needs to run at next, until now it doest love me ;-) |
