i am using it on a z6. from what i understand, the stock rev limit is 6800, but mine sometimes kicks in early(6500), but even still, the rev limit, if i remember correctly, on a z6 is 7200. so is there any cheap way to increase the rev limit on the ecu?if not, would the msd 6al box work? also what is a good crossover point for vtec on a z6 in an all motor application, i am using 4800 right now, nice smooth transition.

 

chip the ecu w/ turbo edit.

 

ok well the pm6 rev limit is supposed to be 7200. mine kicks in earlier than 6800.WHY! might it have something to do with why my fan wont cut on?

 

do you have any check engine lights? that will do it for you. or if you are revving the ---- out of your car when it's cold, there's a cold rev limiter.

 

What kind of tach do you have. I have seen like three autometer's read lower rev's then what it really was and even stock ones get off a litte. And if its a NA d-series 400 rpms isnt going to do a dam thing boost that thing.

Sounds like cold rev limit to me. I've noticed my that my new ---- box Civic hits it even when its warm sometimes. No problem though, its already chipped and running a NA TE program. :P

Steves right though, A6's take a big dump at 6k anyways.

 

i do have a CEL, i keep breaking speedometer cables for some reason. it hits it whne its warmed up, i dont like to run it unless it is. o and its a z6 using a pm6.
