![]() "Refurbished module for ACDelco", part: 19209822. It turns out my PCM was swapped by the previous owner (by a repair shop, for unrelated reasons), and what was installed is a generic GM PCM, not the native LSJ PCM: I figured out my issue regarding no voltage on the bypass solenoid. We've replaced the pump (I can see the intercooler fluid burbling), and now IAT2 is at the levels of 140-150F. I've recently started to monitor my air intake temp after the supercharger (IAT 2, sensor PID: 222006),Īnd after reading over 170-180F IAT2 I realized that my intercooler pump is not working. My intercooler pump is working, so IAT2 temps shouldn't be the reason ECM would limit the boost. Let me know if anyone knows the correct PID to monitor wastegate solenoid duty cycle on Cobalt SS lsj (or even LNF, it could be the same). ![]() That allows to enter custom sensor PIDs to monitor. I don't own the HPTuners setup, but have a ODB reader and Torque app, I would like to monitor my wastegate solenoid duty cycle. This leaves me wondering whether it's the ECM that does not command 100% duty cycle at WOT for some reason.Ĭommanding 100% duty cycle shuts off that valve (allowing full boost).īy bypassing it I disable ECM control over the supercharger (I get full boost in this case). Whenever I bypass the wastegate solenoid, the car boost to 12 psi at WOT without any problems. The car is supposed to boost up to 80 kpa (12 psi) stock, but for some reason my boost is limited to 20 kpa (3 psi) at WOT.
