Title: ECU swap to wideband 018H Post by: djholtz on June 25, 2016, 05:25:07 PM Hello to all,
i have an Audi TT 225 with APX engine. This engine uses a narrowband O2 sensor for lambda regulation and an Ecu 018AE. I bought a wideband Ecu 018H and wideband O2 sensor with the purpose of continue improving my car, in combination with some modifications on motor and its components. For change Ecus i did a properly modifications on wiring. My car's motor doesn't have VVT, rear O2 sensor and EGT sensor, so i disabled them. I also deleted SAI fisically and on ecu's file, and N249 since i use my dump valve connected to inlet manifold. I also changed a few things like TABGSS and KATOFF, copied MAF correction and linearity maps from original ecu. After all this, everything looks good but i have the DTC P1650 - Powertrain Data Bus: Missing Message from Instrument Cluster. I have searched around and i can't find what causes this DTC and how can i solve it. I would like to have some help please, i would like to continue my work with this swap finished without DTC's and everything working good! BTW, i attached the original file and the modified file. The modified file has all modifications for my motor like i described before. If anyone can have a look i will appreciate! Thanks for help, Best regards!
