Sorry I am a beginner and I'm using a language translator and I don't understand what you write. I also dont have the instrument to read this ecu ECM-6BT8591A 00 or 6BG8591A 00.
Can you help me with a sugestion regarding other module or programme witch can modify ECM-6BT8591A 00 with a procesor M32176F2VFP and external eeprom 95040.
Does Ecu have k-line in 18 pin or is RX TX? At diagnostication we use a cable with interface VAG 409, and the data ar read/written through 7 pin from OBD port.
