Title: ME7.5 output via CAN Post by: geos3 on July 12, 2020, 01:25:30 PM Hello,
can you tell me or give me a hint, how to find adresses where ECU sends or can send data via CAN - Mini CAN protocol. In Audi S3 I know it sends calculated torque, but i would like to send some important values like EGT, req lamdba, actual lambda, retarding angle etc. Thanks in advance EDIT: I did some search and it looks like ECU needs to be reprogrammed. Not flash. If so, then it is mission impossible. I will attach adresses that I am told needed to be changed/added Title: Re: ME7.5 output via CAN Post by: geos3 on July 12, 2020, 01:49:38 PM Mini CAN protocol priority: not used
