Are you referring to my issue? I haven't been reading this whole thread - only issues that pertain to me.

With a little R&D, absolutely.

^^^ tricking the BSM is pita, I'm sure tricking the ECU is no easier... I wonder if it would be less hassle getting an ECU from an MT?

I'm sure a programmer could re-write and not have ECU expecting signal from TCM, but getting one to have the time (and willingness) might be impossible.

Contact UpRev and see if they can dig into the code and change things?

I already spoke with uprev,

Since my cruise control stopped working( i have no rear end swap)

in the email back to me, they mentioned that if you swap the rear end that the CC will stop working, and they have no work around for it.

^^^ we've already established that switching rear fd doesn't mean you'll lose cc.

But expecting them to find a fix isnt going to happen - they are a small team of good people (with basically one programmer) that can barely keep up with the demand for existing ECU needs. There is no way they will take the time for something like this.

It's just a hall effect sensor. Falsifying that should be pretty easy.

yea I know we already know that, im just saying what they sent to me, and what I should have said what you said very nicely for me about them not being able to take the time to work on something like this

I'm pretty sure he was talking to someone else unles you used similar stub axles?

You try the neutral brake switch thing yet? That would seem to be the easiest one try first. If you still think that might be one of the causes.

Time to get an ECU pinout for a 6mt and auto and start comparing them?

NO, i was referring to the 2 people with the G37 pumpkin swaps.

The downside to tricking the ECU by doing this would be that in the event you need traction control to respond the computer won't realize there is a problem and therefore will not adjust as is designed.

^Not necessarily.
If the stub axles have the wrong number of teeth on the wss, and you correct for that, you're actually helping correct the traction control that might otherwise not work.

No, haven't tried it yet. Won't be able to for a couple of weeks, I don't have my car right now.

I'll do what I can with the shop once I get it back. I can't switch to a 6MT ECU because the 6MT ECU for my year is for a revup.

If I bought an older ECU it won't work properly because I have wideband o2 sensors and older years require narrowband sensors, from what I understand anyway.

oh boy, ur in a pickle... how often do you use cc anyway? You might have to just pretend you have a Z with no cc...

Yeah, so thats why I stayed with my stock ECU. I don't use CC that much, but I want it for map switching with uprev.
