    Is this even possible?

    I have a guy who brought me an E38 and a T42 ECM/TCM combo and wanted a harness built for a gen 4 6.0L that has been built to a 7.0L or close to it. So I built the harness and now I'm going to start programming it. When I bench flashed the ECM/TCM with the harness, its telling me that the E38 is from an 2011 5.3L with a 6L80E. Now will that ECM work with a gen 4, 4L60E and T42? Or am I just going to be chasing my tail trying to program is combo?
    Any help or advise will be great.

    What about using an E38 LS3 program and the T42? Shouldn't the E38 just run the engine and the T42 the trans, then change the REPTOS signal from the TCM to the ECM that of what a normal 4L60e is?
