    To my knowledge GM did not use the '0411 with a 4 cylinder, so it's unlikely a V6 or V8 operating system could be easily modified to run a 4 cylinder.

    GM used the E37 ECM on 2007 - 2011 GM 4 cylinder engines (2.2 / 2.4 liter),with coil on plug ignition. With some advanced fabrication, the E37 camshaft and crankshaft sensor inputs could be configured to the 22Re, allowing an E37 to run a 22RE with coil on plug ignition. Both EFI Live and HP Tuners support the E37 ECM.

    Attached is the '0411 CKP_CMP waveform relationship (V8 coil on plug ignition). I wonder what the E37 4 cylinder CKP_CMP waveform relationship is for coil on plug ignition?
