Launch Control AFR's??
I was just testing the launch control / 2 step on my evo 8
it is from a tephra rom V7, (my car didn't came with a rev limit stationary), left it at 5k rpm
Works great, but my wideband goes lean (20 afr) when the launch control / 2 step is on
Shouldn't it go rich? since ignition is cut???
Is this ok, being lean during the 2 step?
Thanks

No Fuel gets cut not ignition,
You will need to fatten up the AFR Map in your Launch Control fuel map,
Set it for around low 9's and test it, then adjust from there
