You're right. I have not held a long sweeping drift. I drive an fb with a na 13b.
I have driven many events and heard rotary, sr's, rb, v8, jz both pros and local drivers hold big 3rd/4th gear drifts without having to bounce the limiter. Bouncing off the limiter isn't going make you go any faster. Why not just have some throttle control?

That being said i realize there is no point in arguing over a forum about someones opinions. Especially when it comes to drifting. Personal style being the basis of it.

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 used a rtek 1.8 with ID 725cc and 850cc injectors and a bnr stage 4. It blew my motor by leaning out way to bad on cruise. I got off the highway after 2 miles and boosted once, bye bye coolant seals. You have to use outdated tech when running rtek i.e. bosch style fuel injectors. If you want to modernize your engine I will always suggest Piezoelectric injectors and standalone ecu for maximum tune-ability. Rtek is not able to adjust for, injector dead time, fuel pressure, fuel temperature and battery voltage, all variables that can change the actual amount of fuel injected vs the projected amount.

The Ignition timing rev limiter is the best way to go and if you are not sold on a Haltech, MSD ignition controllers have rev limiters built in that will fit your application. MSD 6al box @ $250 + Rteck 2.x @250 = One Haltech.

ignition cut always better than fuel cut. always.

the chicago drift scene is permanently stuck in 2nd gear, so maybe get a taller final drive?

Holy fuck i just spit up laughing!!

If you can't afford a decent ECU then stop modifying your car right now because you clearly cannot afford it. Why the fuck people cheap out on such an important part of the car is beyond me

I bought a turbo engine setup from a friend who ran an Rtek 2.0 on an s5 turbo for two years and haven't had an issue. I have had the setup for two years and had no problems. 4 years of drifting and the Rtek kept the same engine alive the whole time and still going making ~250whp. The rev limiter is definitely something to stay away from though, otherwise I think its a good upgrade until you can afford a Haltech or something
