You mean between shifts and when deaccelerating? I don't get bangs there because it cuts fuel immediately when lifting throttle. Rev limiter is ignition + fuel cut strategy and it's like AK47 gunshots when spinning 2nd and 3rd to 8200rpm's. :mrgreen:

Try to look into fueling -> fuel cut tab and see what happens when you change overrun fuel cut decay rate and resume enrichments. I really have no other clue other than just bump up fueling in the vacuum cells also. Maybe injection angle might have a desired effect if you try to inject "too late" in the low vacuum cells when lifting throttle.

the folowing wil only make flames and minor bangs:
- go to your fuel cut tab
- make sure it wont cut fuel under deaccel
- bump up either condition under which it wont cut the fuel (fuel cut underpressure/tps limit/rpm limit)
- check the box with (dissable spark when overrun....)
- make make the low map cell's in your VEtable lower than lambda 1 (you need a lean mixture for it to self
combust) experiment with the exact lambda value you need for your pops.

you are now obligated to post a movie of your result here :mrgreen:

Lower than 1?? Then it would be rich?

For those of you out there running the Eurocompulsion Pops and Bangs update is it worth it? I am tempted to get it however I am concerned it might be a little too obnoxious for daily driving? Is there a way to have it only on in sport mode perhaps? How does it effect fuel economy? Let me know your thoughts Thanks

It depends on how aggressive you set it. I personally like it and it only works under certain conditions. Driving normal should not do it. You can activate it with switch
