My son has a 2009 HHR with a 2.2 Ecotec motor and Automatic trans. I bought a Supercharger kit from ZZPerformance and also had the PCM Flashed by them. Well from day 1 the car runs great until you punch it because this sends the motor into "reduced engine power" and also illuminating "service ECS" and "service traction control" lights. I sent the PCM back to ZZPerformance and they changed the tune but it still goes into REP whenever I accelerate aggressively.
The motor:
2.2 Ecotec
M62 Supercharger boosting around 8 lbs
new LSJ throttle body
60# EV6 Siemens injectors
4 bar MAP sensor
cool air intake
This is when I purchased HP Tuners Pro to see if I could avoid shipping the PCM back and forth. I've attached the latest tune file and two scanner files where the car goes into REP> And I thank you in advance for whatever help can be offered.
