How to read a Chevrolet SIM2K-D160 ecu with pcmtuner?
Use this in Module 30, 1,3,5 – ECU ground (just connect one of the contacts)
77 – CAN-High
78 – CAN-Low
76 – K-Line
2 – +12V (ignition on)
4 – +12V (power supply of the main relay)
6 – +12V (non-switchable power supply)
You may not be able to do this ECU in BSL 53 as main processor is MPC756MXP56 Second Processor TC1738.
You could try OBD Module 30
2.0L, 2.5L (SIM2K-D160) But failing that, you would have to do this in BSL mode 53
