I'm working on swapping an E39 LAF/LEA 2.4l direct injection ecotec into a standalone project w/ a t56 manual. The problem I've ran into is that there are no manually equipped cals to use. Is it possible to convert an auto file to manual. The camaros with the LFX sidi v6 use the same E39 ecm but with a manual cal the vss inputs directly into the ecm. I'm positive I'll run into lots of issues trying to run this motor on an auto cal without a tcm and no vss signal.
Any ideas or tricks to get this to work? Possible to take a manual 2.0l LHU cal and change enough stuff to get it to run the NA 2.4 LAF?
