On the ProEFI website it says it works for 03-06 G35 and 350z. Doesn't say if it's 03-06 manuals and/or automatics. I'm guessing it's only for auto cars that are Non-Revup. SP lists ProEFI 48 as non-Revup only.

Is there any ProEFI 128 users here who are using it with a Revup or know if the 128 works with a RevUp? Haltech seems to be the only option now.

 

Yes the ProEFI 128 works with RevUp motors. There are a couple of guys running the ProEFI 128 in there RevUp Z's.

 

I know Glex used to have the ProEFI for a short time and he has a Revup G35.

 

Yep, the ProEFI will work with the REV UP
