02 Saturn 1.9L DOHC Turbo MS2 v3.57, GM OBD2 success

Post by TruboSC2 »

It took the guy I bought this from 2 years of trial and error but finally all the bugs are worked out even the stock tach works. OBD2 Saturn's can be Megasquirted and actually quite easily. Tuning was the hardest to figure out but wiring was a breeze. I have the diagram that should be simplified for anyone to use with some minor corrections. Pin 36 is called Spark A and you can split the signal from the crankshaft position sensor (VR) to the PCM. That's it, $570.00 later and 4 hours you have a Standalone ECU and full fuel and spark control.

Where can I purchase the simplified wiring diagram & Megasquirt for my 2002 Saturn SL2?

Are you willing to share your MSQ file? We have a 92 SC2 (obd I) that we road race and are considering converting to an MS2.
