BEE R Rev Limiter for 370Z?

AstatenateZ

He said he isn't comfortable installing the BEE R even with the FSM as reference for the pin and wiring diagram help. He would rather just have the car retuned in Dallas where it was originally tuned. He just didn't know if UpRev allowed for ignition timing. I told him it was. You can have ignition advanced or retarded correct? So couldn't he just have his tuner. Retard/slow the ignition timing at higher revs say from the 7,400 rpm and up and run rich from 7,300-7,700 rpms. That would be a richer mixture in the upper rpm curve ONLY correct?

Cause that would mean more fuel from 7,300-7,700 rpm AND ignition slowed from 7,300/7,400rpm-7,700 and then fuel cut being at 7,700. Wouldn't that be the correct way to cause a rich mixture in the upper rpm range via UpRev instead of using a piggyback ECU. Or having to worry about all that.

Excellent idea.

I'm in the same boat as you - I don't fully understand how to tune a modern, computer-controlled engine. What you outline makes sense but I'd take it to a real tuner instead of trying to DIY.

Yeah he is. He's going to take it to get tuned in Dallas where it was originally tuned. And he's going to have the ignition delayed/slowed/retarded. Whatever you want to call it. And have it run rich from 6,500- until his rev limit (fuel cut) which is at 7,500 or 7,700 I can't remember off hand. And that'll cause a rich mixture.
