How safe is the rtek rev limiter in drifting?
I don't know anything about this so I figured I'd ask the kind dudes of rx7club. I've always had this perception that the rtek limiter is not safe to bang off of because it is a fuel cut and can cause dangerous lean conditions, so I've always tried really hard to stay off the limiter to save my motor and such.
That's sort of a pain in the *** because if you have to extend a long straight or something it's nice to be able to just sit the car at the limiter. Driving while staring at your tach and keeping it from touching limiter is a pain and annoying.
My question is, am I right to think that bouncing off of an rtek limiter is unsafe? Is there anything I can do to make a safe rev limiter?
Thanks bros

RTEK is garbage. dude trust me - you're WAY better off having stock ECU, SAFC, wideband, gauges, FCD, tons of fuel, and close to stock timing. **** that RTEK crap.
RTEK still utilizes fuel cut rev limit. something really strange, but both JTP's S5 ecu'd turbo car, and my S4/N332 ecu'd turbo car both railed rev limiter a bunch and (mine) never suffered any damage from it even with the wastegate unhooked 15-18psi.
stay stock ecu with the above precautionary items, or bump up to an E6k. I love my E6k. ryan got me hooked on it. ecu was like $500, but with tuning (twice), wiring harness setup, and clips/random bullshit i think i'm in like $2,000. definitely money well spent though. my car just burns tires and loves it. you need that too dude.

I have a stock ECU laying around that came with my imported motor, I could switch to it, but SAFC seems scary to me! The car seems to run at the AFRs I want and stuff (10~11:1 under boost, 14 when cruising), and I had a local dude that is pretty clever (shook motorsports) make an ignition map that he says is very conservative, so I always figured I was pretty safe but maybe there's something I don't know?
To be honest I've never fully trusted my setup so I've always just run wastegate pressure. I'm still at like 7psi peak boost in 2nd and 3rd.
But if I do end us staying with the RTEK, is there a way to make a safe rev limiter?

I had an rtek. Blew my engine. Ill never run rtek again. It's just not for drifting. You would have the best chance with a stage 2 rtek. But for that money you could prolly find a e6k. Great for daily driving though.

Yea I have the 2.0 thing on a kouki ECU. I am using last season's motor and it seems to be running well, I put about 15,000 miles on it last year including 5-6 events and a bunch of street drifting?
I had an engine fail the year before, but I am pretty sure it was my fault. I was banging it off the limiter a bit, and I had no gas gauge so I ran the motor completely dry of fuel 4-5 times doing highway runs in 5th gear at full load and like 12psi of boost. Basically I was an idiot haha.

Been running Rtek 1.7 for 4 or 5 years.
I've hit rev limiter only a few times but live in that 6-8k range when drifting.
My motor is doing fine.
I completely disagree with the stock ecu plus piggy back crap is better than an Rtek.
Haltech is always hands down better.

just putting a down pipe on your car requires bigger fuel injectors which requires a bigger pump which requires new engine management of some type.. sure plenty of people get by with rtek but i mean.. if youre going through all that work to modify your car, you might as well do it right and save some money. an extra 200$ on your initial investment is a lot cheaper than a 900$ rebuild kit + a housing, rotor, possible e shaft, time, patience.. etc
its not my car or my call though. i just try to share what ive learned with others and try to help them avoid spending untold thousands on trying to do it the 'economical' way.

I tried calling that guy every other day for like a week.. i emailed him, left messages, everything. not one returned call or e-mail. I had planty of money to give him for a E6k install and tune. I guess he's prolly rich and didnt want anymore...

^ he emailed me back a few hours ago.. Now I feel like a huge dick for that post. Seems like a super nice guy, I look forward to actually doing some business with him in the future.
Thanks Ilia.

My friends drift car ran the 1.7 for 5 YEARS with NO PROBLEMS and my same setup but with a front mount. 3 years ago he upgraded to a 2.1 and made 260WHP on a street tune he did himself a few weeks before a dyno day. He's still drifting on this tune, motor and ecu with NO problems AT ALL.
I'd never use a fuel cut of any kind for a limiter but I stand behind my Rtek 100%, a system is only as good as it's programmer/user. It's proven itself over and over and for less then $500. Plug it in, set your parameters and go drive. Done and done. Yes, there are better out there but unless your going for bigger numbers like 300+ at the wheels the Rtek is fine.

First off I had/have an rtek 1.5 and safc on my 6port turbo and drifted it hit 8k rpm at least once a night for about 2 years. Mever had a problem.
Bouncing off the rev limiter is not the best thing for the motor whether it's fuel or ignition cut. A limiter is a safety device. When I hear drifters bouncing off the limiter constantly I think SHIFT!!!

You have never held a long drift have you? Letting off to shift to the next gear while holding a drift is extremely difficult, and practically futile. It upsets the car really badly, especially in a turbo rotary with a dynamic power band.
