Imaginary Rev Limiter Intermitantly? / oil temp?

[nickmerronesucks]

Hey Guys,

Have experienced this a few times at the track(Drifting).

I'll clutch kick the car and get right back into it and it seems to have almost like a clutch activated rev limiter(dont quote me on exact RPM).

The car was pretty stock when i bought it but who knows could of been tuned and returned back to stock half assidly?

Just wondering if anyone has any kind of outlook on this.

Car is being driven with ABS removed as well so its not a traction control related thing or anything, had a pro driver hop in for some fun runs and he noticed it too and then drove around the car avoiding clutch kicks.



Also after quite a few hot laps got a flickering oil light, oil level ok but also hard to judge since im sure it can read high on the stick from sloshing around.

Any kind of thing I should be aware of on that? Assuming I may of just gotten the oil really dang hot and she was low on pressure, I killed it and parked up after that. Car seems fine now. I plan on dropping the pan this week.

your profile says your car is turbo'd, which would mean the car has a tune. have you ran a logging session during one of these times?

i really suspect your tune, likely something about the shock load to the motor is hitting some sort of software 'switch' that is triggering to attempt to protect the engine.

I apologize, this is a new car.

Bone stock other than angle kit & coilovers

how is the ABS removed?

i'm wondering if the system is still trying to trigger..

I had a similar experience with a tune, "flat foot shifting" was enabled. Prior to shifting, a light touch on the clutch pedal dropped the spark advance to 0*. Hence: rev limiter.

I like to think this could be right but I’m unsure how to tell if this thing was tuned or not to be honest. It definitely doesn’t feel like it drivability wise lol.

Just removed fuses I think I had a brain fart typing and forgot a word Lol

It’s very inconsistent, for example I’m on the bank of English town and need a little UMPH So I give her a clutch kick and boom now I’m at 3500 rpm rev limiter aimed at the wall lol

i would try the pedal dance to remove the vehicle slip corrective actions from the equation.

if the vehicle detects a slip, it typically activates ABS for individual wheels, as well as cuts throttle.

i think you're getting the throttle cut where the car is trying to 'correct' the situation, and would be activating ABS, except the power to the module no longer exists.

When accelerating in 2nd or 3rd, 3/4 to full throttle, put your foot lightly on the clutch pedal. If the engine almost cuts off, FFS is working.

This is what I went through.

I run no ABS fuse all the time to avoid any of that

If car is ecutek tuned I'd say tuner has activated flat foot shift feature, whan you clutch kick it won't let the rpm increase of current rpm.


Fix will be to disable flat foot shift feature in tune or at least disable it on one or more of the map me des if you want to clutch kick to get wheel spin


FFS is engaged if throttle is over 85 percent and you press clutch


Flickering oil light is a worry it means oil pressure is dropping below about 3 psi.


It's just a simple pressure switch it doesn't go through ECU. So if that's real and pressure switch is not broken you oil pressure is dangerously low


I'd assume your running an oil cooler and at least 5w30 or 10 w40 oil and you oil temps are less than about 120C max if not I'd check that out asap before you need a new motor
