Got it to gargle and pop really nice when warm engine.. But one thing I dont understand is why the idle got really poor when warm engine and STFT seems to work only at low throttle and under 2300rpm?

Here's my attempt,

Managed to get it flaming really well on over run. Less bangs but I prefer it that way, track noise limits don't like bangs haha.

Yeah when I get a chance tonight I'll post settings - it works really well. I'm trying to tune out the bangs and just have the flames Tongue

KFZWMN to -30 on the first 3 columns only between (4500 rpm and 6500rpm)
CWSAWE to 01
KFZWOP subtracted 20 from 1st column and 10 from 2nd column
KFNWEGM to max rpm
KFTVSA 2.5 for last two columns (I think this is delay time in seconds before fuel cut) I figured longer meant more chance of flames

I then added some fuel with lamfa between 4500-6500 rpm going for something like 12.4AFR (for the 50%) row as I figured I'm never cruising at part throttle doing above 4500rpm so the only time my car should see that area of lamfa would be when I lift off the gas at high rpm.

Not so much banging but lots more flames. Banging seems to happen when fuelling ends up at stoich below 4500rpm.

Does anyone know how I cut the fuel below 4500rpm as I don't really want the pops and bangs so much?

there is no reason to use KFWEGM then (btw there is skyhigh egts when using it even at cruise)
keep it stock and use only KFTVSA - its delay in seconds before fuel cut kicks in (try to play with KFTVSAKAT if KFTVSA wont work alone)
manage pop rpms by KFZWMN & KFZWOP

Thanks, have now set wegm back to stock. kftvsakat to zero below 4k rpm as I don't want any fuel below those rpm's. KFSTVA set to 2.5 for last two columns. WOP and WMN same as i stated in my last comment.

What are your settings? If you set KFTVSAKAT to say 10200 i think that should allow over run fuel all through the revs. Then make sure KFZWMN is lowered sufficiently all the way down from redline rpm to say 2.5k for the low load columns. Also edit KFZWOP for low load (first and second lowest load columns is what i changed) it should then pop all the way down the revs.

The problem is the lack of CWSAWE if I'm correct. It will only go into overrun when the clutch pedal is pressed... Unless you find CWSAWE and enable the overrun bit...

Maxing (or raising above you rev limiter) KFNWEGM will disable fuel cut entirely and (so long as KFZWMN, KFZWOP and KFZW(?) are set correctly) it'll pop/bang all the way down overrun.
