I just bought my RX-8, used of course. And It revs to 9500 RPMs and doesnt have the redline indicator noise. Is there any ways to tell if racing beat has flashed it or not? The Dealership wont disclose the previous owners contact information to me.

 

Why do you think it has the Racing beat flash?

 

"We raised the rev limit from 9000 RPM to 9300 RPM to take advantage of the increased power available at that RPM once the mixture is changed. Testing has shown that 9300 is an acceptable RPM for the engine. Mazda chose 9000 in part because power was dropping so fast at 9000 there was no point to revving further. Now, that is not true" - Racing beat REN v1. tune.

Thats why, i was considering getting it, but since it revs above 9k already, and doesnt have the redline indicator noise anymore, i figured the previous owner might have already had it done. Thats why i was asking if there is anyway to test it without having racing beat check it.

 

No, don't waste your money. Read the FAQ and look for the "New Owners" thread. There is no power to be had above 9,000RPM.

 

Thats great and all, but i was asking if there is a way to test if there already is a flash on the ECU.

 

thats not true 9k, the RB flash does indeed provide more power above the original redline. instead of dropping off it keeps building past 9k

There are several reason you may not hear the beep- its very soft for one and it may be that the intake noise is to loud. secondly it sometimes can get turned off. there's another recent thread about the fix ill go look for it for you.

The tach runs a little high and the engine revs fast. by the time you see its showing 9500 on your tach its probably only 9-9300. If you had the RB flash it would run all the way to 10k before the cut off.

 

here https://www.rx8club.com/showthread.p...highlight=beep read this thread about the beep

 

Reading through all the dyno talk that meyer and other Koni teams have done it seems there is not really any power above 9,000RPM. Let me look Either way I have not seen many positives results of the RB flash and it is a PIA and expensive.

OP, if you want to know just call Racing Beat. It seem dumb to me that you think it does. Oh, and you are not actually revving to 9500 because the factory tach runs about 500RPM high.

 

I dont have an aftermarket intake =(

 

sorry wrong link read this one https://www.rx8club.com/showthread.p...highlight=beep post 6

 

There is a reason why people 'dynamically balance their rebuilds' beyond what the factory originally put out from Japan, and that is to address the wobble of the rotors at that high RPM. Even with mine balanced, I still shift around 8K. My next build I will be even more **** and lighten the rotors as well...

 

OP, I hope you are premixing

 

What actual results have you 'seen'? I've tracked w/RB ECU many times. Definite and noteable 'under the curve' response improvement... that's the real meat of the mod. And high end is actually there...rather than missing...so it regains some omph up there totally lost to emissions/egt control.

Rather a useful pnp power mod that is what? - couple hundred $$? You think that's expensive? Ask some race team what they spend tuning a car.

PITA? You take out and put back your ECU - omg I need a rest. Downsides - loose your cat or toast it within minutes, literally; also wo street rev limits on a street engine bad things 'can' happen to a rotary.

To the OP call RB they should have the ecu serial# records I would guess. Or you can take the ecu apart and see their taps to do the tune if they're there.

 

9500rpm on your tach is really only 9300rpm roughly

 

The point of the RB flash wasn't to necessarily add more oomph beyond redline, but to more so add a bit more power under the curve as well as drop the activation temp for the fans. I'd rather spend $300 on the Race Flash than $700 on ap via mazdamaniac. AP via Cobb was an even worse joke IMHO.

 

Ah, $300.00? I thought it was way more for some reason. Either way the process is a PIA to get the tune and I have never seen any real dyno results of the RB tune. I can say I have seen the results real time on the dyno with MM's tune. But I have yet to seek MM's services, I am giving the tuning a crack myself

But I guess for $300.00 the RB might be a good idea if there are real gains. Hmmm. Either way, I don't see why this dude thinks he has it

 

I was wondering if i had it because i thought the rev limiter was set to 9,000, instead of 9.3-9.5k and racing beat flash said they reset it to 9.5k and remove the buzzer, and i bought my car used, so i wasnt sure what all the previous owner had done considering it already had some upgrades on it.

 

Is the gain in power really worth revving to 9.5k and wears the engine down faster?

 

As was said before, the meat of the flash is with far better midrange response (power under the curve) in the useable RPM range (5-8+). The higher rpm limit just adds a bit to the already track-usefull wide-rpm range of the engine in each gear.

As to wearing the engine down, I'm not sure that's relevant, as whether it's 8k-8.5k-9k or 9.5k it's not meant for you to stay there and drive at the limit constantly, but as an upper limit to use when applicable and needed in certain situations.
