so i was looking thru the old posts...

and to clarify
you CAN disable the rev limiter WITHOUT getting a new chip
stop saying you NEED to chip your ecu to have no rev limiter
you dont know what you are talking about

Knight Sports sells a Rev Limiter Cutter
Greddy's Rebic LC disables Rev Limiter

and that is just to name a few. I am SURE there are more electronics out made for FC to disable their rev limiter.

 

Just to clarify, isn't that rev-limiter either fuel cut, or spark break up due to the inadequacy(sp?) of the stock ECU to keep up, and the fact that without major porting you will not make much more power in higher than stock redline rpms?

I see no point.

 

I'm pretty sure the point of chips is not to *disable* the rev limiter, simply to raise it...

Rev limiter = good

 

Why would you take out the rev limiter? It goes up pretty damn high to me. I mean if your taking it out just for the hell of it you should be kicked. rev limiter are there for a reason. But a rev limiter in the new cars can go to hell.

 

Hes just making a statement guys hes not saying its going to make any difference.

 

USDM did not have rev limiter ( i thought i had one but turned out to be fuel cut) Japan DOES have limiters.

 

yea ive wrapped my t2 out 8200 and i didnt hit any limiter. and no i didnt do that on purpose

 

****, unless u are ported or a TII highly modded, why would u want to go OVER the rev limiter, im NA, have beaten cameros, and i never even hit the limiter, btw, what rpm is 90 na set at for the limiter?

 

^ read the post a few above you, and you'll see the US market RX-7s dont come with a limiter.

However, I've taken my S5 N/A to 9K on the stock ECU and hit some major spark breakup. Besides, the stock ECU really chokes the power up there.

Since I went MegaSquirt instead of the stock ECU, it climbs to 9K just fine The power keeps climbing but I'm not about to go over that on stock stat gears.

EDIT: I should also add that the stock tach is not exactly accurate, it's usually about 200RPM off from my observations.

 

thats pretty intresting, wow, i didnt know it was that much, well, i dont usually take it above the redline, hell ive only done it once and it was on acciedent, but regard less, i never plan on taing it above red or 8500 unless im ported, but i feel like ive said too much already already on someone elses post. btw i plan on upgraded 8.5 mm wires and ngk plugs w/ stock ecu, how far can i take the ecu w/ speeds under 130mph?

 

USDM has limiter.

 

here are pictures of such said unit.
The Knight Sports model works on S4, and only does rev limiter cut
The Rebic LC works on S5, does rev limiter cut, fuel cut defender, and speed limiter cut.


I am not saying there is much of a reason to disable the rev limiter... but such units EXISTS, and they are PIGGY-BACK... soooo... dont spread any misinformation... now that you know.



Also... the reason that the S4 guys doesnt think they have a rev limiter could be because...
1. their tach are off
2. their ecu makes their engine run way rich past 6k, and it feels like the engine makes no power up there - and you cant even "feel" the rev limiter. run a wideband on it and you will see what i mean.

 

So youre saying that you have proof of the rev limiter existing because two Japanese companies, who only make parts for Japanese cars, make these parts? Just because it has English on it does not mean it was designed around USDM cars. Show us where the rev limiter exists in the factory circuitry or engine maps.

 

so you are saying neither of these parts would work for our cars?
there isnt even a real diff between the USDM and the JDM cars.
the only FC that could possibly came WITHOUT rev limiters are the ones that came with a distributor.

what are YOU trying to prove?

 

What are you guys talking about? My S4 has a rev limiter at 7,800. The shift chime goes off at 7,200 and I can feel the fuel cut off at 7,800.

It's not that I race, but I like to know my car, and what it can do. I know that I can rev to 7,800 before shifting if I wanted to.

Would it damage the engine to go up to 9,000 like some people mentioned?

 

on my s5 n/a i had exhaust, intake, msd, and a few other bolt on mods and it would pull to ~8200rpm but after that it would just make noise up to fuel cut at 8600rpms. there is really no reason to rev much past the redline on a modded or stock car. like people say you really need alot to support that kind of rpms.

 

^^^ it is because your car runs VERY VERY rich before the rev limiter

 

USDM FC's DO NOT have rev limiters...period.....argue all you want.....we don't have them.

 

you are WRONG.
I don't know where you got the idea that USDM FC's dont have limiter, but I think you got a few things you need to learn before you pull off an attitude like reted - when you are wrong.

 

Every US FC I've worked on has had one. Occurs ~1000 rpm above redline.

I've proven to other that they exist by fooring it above neutral. Its always cuts in, though often the tach reads low (measured with external RPM pickup.)

It is not just ignition break-up.

 

I know for a fact that my TII has a rev limiter, it cuts in just below 8K rpms..

 

lol........ok guy, go buy your rev limiter remover....lol

 

do you have an FCD? I've recorded 8500 RPMS on my AVCR.....( i really had no power up there but I didn't realize it).........I have an NA with TII drivetrain,ECU and all the electrical (except for the body electrical....duh) AND the NA tachometer and theNA has a higher redline (by 1k) and I've shifted above that MANY TIMES (on accident.......more like carelessness)........but feel free to invest in your rev limiter thingy.....

 

Don't know what you're talking about, but yes the FC has a rev limiter...

 

if you really have "no rev limiter"
i dare you to pop open the ecu to show the stock chip...
no... i CHALLENGE you to pop open the ecu to reveal a stock chip

why does it make no power up there?
because your stock ecu prob made it run so rich that it wouldnt really rev higher.
