anyone know why when I'm not moving my rev limiter is set at 4k but while moving if I rev it in nuetral it seems to not have a limit?
thanks guys
Just out of curiosity, why are you wanting to rev so high in neautral? I hope your not wanting to just dump it into drive from high revs
Dont quote me on this but I think it is set like this to safe gaurd damage to the engine, desides you dont need to rev so high while not in gear any how. Hope this helps?
I'm not planning on doing anything like that and I don't want to change how it is, I'm just curious why it is like that
Thats how the PCM is set up, you actually have 2 rev limiters, moving and not moving as its listed in HP tuners
Its so idiots dont rev it to 6500 at idle, at least Gm did something right

thanks rodimus, yeah it's a good idea on GM's part, but does it damage anything if u bounce off the "not-moving" rev limiter? not that I plan on doing that but have so in the past, just wondering?
nope its a fuel cut rev limiter, doing it a few times wont hurt anything but I wouldnt make a habit of it, it works the same as the moving one

im sure they made this not only for idiots that want to rev it up in park but also lets say there is a situation where the car is in park and something falls or somehow something lands on the gas pedal or throttle and it would rev up but would have the protection of the limiter to keep the engine from going ka-BOOM
I wasnt trying to be an a@#, some ppl have asked that same question so they could do neautral drops at higher revs. Sorry if it came off the wrong way.
not much of a mystery since it gets asked alot , a quick search woulda told you the info you needed
it was done to help save the trans missions from droping into gear at high rpm and causing failure , is the biggest reason

Kinda hard to do neutral drops from 4000rpm in most cars that way. I'm sure there's some that can. My GTP probably can, but i've never tried it.

That can't be 100% so. My 96 z24 auto will not rev over 4k in park or N, but if I put it just between N and D or Nand R, or P and R it will rev to normal rev limiter. It is in gear but not in gear sort of. Maybe it has something to do with it being a 96.

Did anyone else notice the "performance chip" part?
I did but ignored it since the question was of the dumb newb style anyways. LOL.
