I have an engine swapped Triumph that currently has a second gen L61 with the E37 ECU from an '07 G5. Fun combo in a 2000# RWD car; dyno'd 145HP at the wheels.
I have acquired an LSJ from an '07 Cobalt, complete with everything except the MAF and a working intercooler pump. I do have the P12 ECU, minus the blue J1 connector.
Due to space constraints, I would like to delete the LSJ cam sensor; I believe that would require swapping to the L61 head, coils & reluctor wheel (anything else?) to run the E37 ECU. I'm not sure how the E37 would feel about the LSJ throttle, either.
My question is whether there is any benefit in keeping the P12 ECU to justify "making room" for the LSJ cam sensor, or would the E37 be better for any other reason? I do have an HPT license for the E37, so there's that...
Thanks for any thoughts!
