When changing gears from 1st to 2nd on my mr in manual mode using s-sport i always hit the rev limiter i change gears when the rpms are about 7200-7300rpms it seems the car doesnt shift that fast at all i need to change before the 7200rpm mark,so is this normal this delay in shifiting?
i ask cause when changing from 2nd to 3erd gear i can change closely to the 7500rpm mark and it shifts great but yes the rpms dont climb as fast as in 1st gear.
also using ecuflash i see 2 rev limiters which one do i change?
i want to raise it a bit and is it ok to do this on the stock flash?

thanks friends.

Are you stock? If so..why the heck are you running out to 7500? You've got no guts up there anymore... you're out of the useful powerband by far on the stock turbo/tune.

yeah iam stock just a works drop in.
i go up to 7500rpms cause when you change gears revs fall to 6000rpms if you change at 7000rpms revs fall to 5500rpms believe me the car is faster changing at 7500rpms ive tried again and again against friends ectt....

your risking your engine. With stock tune its too dangerous revving that high. Your car do what you want but most will agree with me.

^^^i have logged my car several times and i have 0 knock going all the way to redline 7531rpms to be exact.
try this use s-sport auto do a run time it a drag strip then change it to manual mode shift all the way to redline without hitting the rev limiter and compare times youll see the car makes a faster time

Yes, that's normal. You need to give the shift command earlier to get the RPM exact where the shift actually occurs. The engine RPMs climb very fast at full throttle in first gear.

The computer does a very good job of reaching redline and shifting when in auto mode.

^^thanks for answering
now would it be ok to raise the revlimiter on the stock tune and if yes how do i do it using ecuflash i see 2 tables which one do i manipulate?
thanks

Just because you see no knock does not mean your not running into trouble.. some others have run into issues running up to 8k on stock springs/valves..

And for the record, my fastest times were in Sport mode with Snow mode.. S-Sport gave me second slowest.. but hey, if it's faster for you, congrats.

thanks OK? Questionable without upgrading internals like valve springs, for example. I'd estimate that the stock valve springs are good for maybe 2 hours at 8000 RPM, maybe 30 minutes at 8500, and maybe 10 minutes or less at 9K. Naturally there will be more valve train wear with stronger springs. If you want 10K RPM, get an RX-8.

I seriously doubt there would be any performance benefit to going beyond the stock 7500 RPM in any case without lots of supporting mods. IMHO. The main advantage to turbo engines is their mid-range torque - compared to their NA brethren.

Iirc ECUFlash has the upper cut limit and the lower recover limit. So it cuts, for example at 7500, then comes back on at say 7300. That gives it a short moment of "engine off" and is smoother. Too wide a range is annoying while too narrow is very jerky. Feel free to experiment but remember a failure at very high RPMs is always very expensive.

BTW - I almost never take my X over 7K. There is sooo much mid-range torque (3-7K) with a little tuning that >7K it isn't needed at all - especially on a road course.

Had one, fuel cut-off is at 9.5k RPMs. However, power started to drop off after 8.5k because the engine couldn't get enough air into it.

To the OP: What exactly are you trying to do? Go faster? If so, I'm certain there are better and safer ways, rather than raising the rev limiter. Engineers put that thing there for a reason.

thanks for answering

what iam trying to do is just not hit the rev limiter in 1st gear
before this car i had an evo8 with 365whp the rev limiter was set by my tuner at 8000rpms it had all the head stock and never had a single problem with it and i made numerous runs with that car and now with the evo x that has a more square engine it should be fine to rev to 8000rpms without any problems but iam asking for experts opinions on the matter,thanks

Had one, fuel cut-off is at 9.5k RPMs. My bad - you are correct. I re-read the 2010 RX-8 brochure and it states that redline is at 9000 (7500 for automatics). I must have been drinking when I first read it and thought 10K.

what iam trying to do is just not hit the rev limiter in 1st gear Then just shift earlier. Remember in the 8 you had to lift off the throttle to shift - and that is not necessary with the SST.

As the car (gearbox) ages, it will learn. But the RPMs change so very fast in first gear that you will need to anticipate and give the shift command earlier.

I don't mean this is a "You're dumb" kind of way but I'd like to suggest you learn to drive the car the way it was designed first - in other words modify your driving styles and desires to work with the car as it is - then take to modifying the car later.

First gear is launching gear and doesn't get used much after that except perhaps at an auto-x (where, curiously, you generally can't launch).

the car was design to go all the way to 7500rpms yes thats the limit but many pro like ams bushur racing raise the rpms to 8,000rpms with a tune of course but what i was asking is how to raise it and if its ok to do it on the stock tune thats all!
