I put a supercharger on a 2008 hhr 2.2 l61. Installed bosch 42lb injectors. Adjusted injector flow rate from tested pressure of 43.5. Calculated to what it should be at 58psi. 43.5/58, square root * tested flow of 42. Commanded eq ratio to be 11.5 afr power enrichment.
Normal driving the car hesitates and leans out past 17:1. Injector duty was showing 0 at those points. Only got a log at idle, touching the throttle a little. Didn't save the driving log. I'm pretty frustrated with it. I've had enough fun trying to get the virtual ve tuning started with the blue cat tool. If anyone could help it would be greatly appreciated.
