Ls1 ecu ???
I just recently purchased a LS1/4L60E combo for my project. I already have a LT1 T56 that I would like to run, and from reading other posts on this forum I should be able to do so with some modifications. My question is, will I need to get an ECU from a T56 car, or will the one I have for the 4L60E work.

Not sure about the LT1 T56 fitting on the LS1, but as for the PCM, you could have it programmed for a manual car.

If you want to use the LS computer to control the reverse lockout, speedometer output, etc., you will need to integrate the T56 wiring into the ECM harness.
