Has anybody tried to install and program a used ECM in a Mercedes of this vintage? I know that Maxisys will program a new ECM but is it capable of downloading the info from the original ECM and loading the info in to a used ECM from a junkyard?
I believe I'm going to need an ECM for this Mercedes. I lost the ground output from the ECM to the bank 1 tumble flap position sensor. The 5v supply and position circuits are fine, it is just that I have no ground on pin 3 of the sensor circuit and that ground comes right from the ECM.
