Sorry for the confusion guys. When I say limiter, I refer to the one created by spark cut (-70 deg timing). To answer the question about my engine limiter (the factory fuel cut limiter) I have it set to 9000 so it’s not doing anything.
Roland is right, I have normal timing at 4800rpm and then spark cut at 5000rpm so it bounces around instead of holding itself.
Also, to elaborate… my setup is normal timing up until 4800rpm and then -70 degrees on all loads at 5000rpm. I then have very rich fuel at over aprox 80% load on 4800rpm and higher (to achieve the bigger flames) I did a very slight change on the exhaust cam timing just to help the spark cut but I don’t think it’s really needed.Before I go trying to figure this out aha, Could I set it to have normal timing at 5800 and then the -70 degrees at 6000? & would it keep relatively enough power in the motor to slide the car while shooting the big flames?

I read it as he has a spark n fuel hole just before shift points.
I think the only limiter situation that would work here would be a sparkcut only.
Super odd but posted my last comment twice lol

Possibly, Hopefully not aha. Wanting to get a limiter on my car that just shoots big fuck off flames aha while drifting on limi

I think hes not going to reach limiter at -70 spark.
He said he was at limiter in the video, What the limiter was set to is the question aha. Could be set to like 4k

This is -70 degrees and 0.65 lambda
What RPM is your limiter set at?

Yes. I’ve got it set at 4800rpm and I’ve got my shifts happening at 4900rpm. I get flames between each shift when I keep my foot flat. The same would happen if you had your car in 1st gear while doing a burnout.
Not the best idea for drifting since it’s such an aggressive limiter. It won’t be smooth like the oem one. I’m sure you can tweak it to be smoother though.
So I could set it up so that if I'm flat foot pinned in a corner no lifting and no clutch work, it will still continuously shoot big fuck off flames on limiter?

Hey, it’s definitely doable. I played around with the spark and fuel at the point I wanted limiter and this is what I ended up with so far. I didn’t need to do any changes to injectors. This was just open loop fueling and spark. Check out Roland’s post about 2step to get a starting point and go from there.
My next goal is to try and get a flame to linger after I release my foot from the pedal. I need to learn how to datalog properly to see though but I think the problem is something related to open/close loop fuel.
Could you have this effect or something close to it while drifting/skidding on limiter?

Has anyone tried messing around with shooting flames on limiter?

Could something like this work for shooting flames while feeding it on limiter? Definitely not good for the motor but would look cool

Hey guys,
Pretty new to PCM and the whole world of tuning. Bought the cable and the software to do some simple tunes on me and my mates falcons. Just a bit stumped atm with trying to tune for higher octane fuel i.e 98. I know its just messing around with timing, But i'm just curious what everyone has found to be effective/safe so i'm not getting detention or pinging in the motor. If you could point me in the right direction that would be very much appreciative ❤️

Tuning a mates car and when I set a fuel cut value it does nothing
For testing purposes i set the fuel cut at 3500, When i revved it up to that in neutral it got up near that value then slowly kept revving past it. Any ideas why this might happen?
