Yea I see where no CC would be from having no CAN Communication to the TCM. But I actually haven't swapped the ECM to a manual one yet. I might need a new ECM here soon though... (Doing some Diag right now because my ECM fuse keeps blowing when the ignition is cycled on. and it only happens when the ECM is plugged in. I have some techs telling me its an internal short and I need a new one. So Saturday I'm getting my hands on a donor ECM to plug it in and see if it blows the fuse. If not then that's my answer. Already checked all the wires, all the grounds, tried replacing the IPDM. Nothing worked so ECM test is the next.) If the ECM is my problem, then I will be looking to get a Manual ECM and program a new key to it so I can drive my Z again. When the Z is moving again then I'll need to Re-Tune (With ECUTEK this time around. Previously was on UPREV) and try again with CC so I can get the features. I did see the BCM does take input from the CIS and CPPS. So Maybe I can wire that in accordingly and get it back. The ECM is what controls CC from what I seen. So it's just a matter of wiring I'm sure.
