Fast / slow rev limiter??? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Mike86 · 08-13-2013, 10:03 AM

I noticed that sometimes when im stopped and hit redline (i know not good i noticed by accident) my rev limiter is sometimes slow like a honda and sometimes almost double speed like a speed bike almost and i can never replicate it im guessing its normal but i was wondering if anyone has had this happen and why it happens!

Thanks mike

Maybe you don't have the pedal all the way to the floor when it does the slow rev?

Mike86 · 08-13-2013, 12:29 PM

Im sure its 100% i can see it on my data log!!

Youve never seen it fast ever? Cause me its about 7-8 times slow for 1 time fast i just hope it doesnt pull timing or something when it rwv limits slow as if atmospheric conditions werent good enough or something

Peculiar. Mine is always slow, I've never gotten the fast bounce. A lot of tunes can change it so it doesn't bounce at all, just sits and holds. That seems more optimal, though the fast-bounce sounds sexy with decent exhaust haha.

ive only ever hit mine in gear, and it is definitely slow.

Mike86 · 08-13-2013, 10:39 PM

When im rolling slowly like between 3 and 30 km/h it holds at 7000 i never understood why guess i still dont haha but when i hit it in gear its slow kinda weird

I wish mine bounced like that when I'm actually moving--it just goes into a
'suspended animation' when I hit the limiter.

Fuel cut is fastest, throttle closing is slowest, and spark retard is in the middle.

I noticed this too with my car, itll bounce slow sometimes and fast sometimes.....ive been meaning to check and see whether having it in gear with clutch in makes a difference compared to just having the trans in neutral.

Ive actually been meaning to ask, but never go around to actually contacting anybody who tunes, with an aftermarket tune(like ecutek) can you change the style of rev limiting?(fuel cut, ignition cut, etc etc)
