370z "Detailed" Manual Swap.

TurboKing

This is a fantastic breakdown of how to manual swap your Z, im preparing to swap mine soon just waiting on a couple parts to come in. one thing i dont believe was touched upon here was the wiring for synchro match (s - mode) did you decide not to use S - mode? or if you did what was the wiring for that?

THE BULL

S mode is a challenge, You'd have to wire up the input shaft VSS sensor, Smode switch and possibly the rear diff since the auto will read a lower speed than what the input shaft sensor reads and even then there's no guarantee.

From speaking to ECUTEK they say they can utilize the CPP switch to enable rev match for base members. Many have agreed that S-mode for what it offers ends up being too much work.

THE BULL

For OP, being that the ECM is converted and TCM no longer communicates it leads me to believe that the BCM is the culprit for CC not to work on Auto/Manual Swaps.

Since the manual Z doesnt have a CAN branch for the TCM and a Manual ECM doesnt take care of this issue, there has to be something(possibly BCM) that expects the TCM input.

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.

THE BULL

Following the diagrams I saw that the CPP CIP go directly to the E3 connector and go directly into the ECM.
On Auto cars you have CAN bridges to incorporate paddle shifters so in theory the a Manual ECM might not do the job. You might have to go as far as the BCM to obtain your cruise.

I just bought a Non-Synchro Rev Match Transmission. For one, it was easier wiring wise. And second because it's not really needed. It seems like a cool feature to have, but I've seen a lot of people that turn it off because they don't use it much. I'm sure you can wire it in, I think it uses CAN info. I remember slightly looking into it thinking one could possibly wire it through the TCM connector. But again I didn't look much into it. You can still buy a Synchro Rev Transmission but not use the feature. All up to you though, for me I find more enjoyment Rev Matching myself.
