Launch Control Backfire

Recommended Posts

Currently trying to setup my LC, but I have backfire that are quite noisy while holding the RPM stage. There are rules with sound limitation, with backfire I won't be able to use it.

Any idea how I could set it up to avoid this issue?

Attach are the current setting and a log I did.

You will most likely have to change to fuel cut if you dont want back fires at all.  Often with ignition cut you can reduce the backfire effect by adding fuel (I know this defies logic), so if you really want to stick with ign cut, then turn on fuel trim, add about 15-20%.  Also, take your limit range up to about 300 and lower your start cut will make it a more gentle limit.
