Re: Pop n Bang on aspirated engine
Just set the timing to -10 degrees on overrun and keep fuel turned on
Makes no difference if its nasp or turbo

Re: Pop n Bang on aspirated engine
you can only do negative ignition on MAP2, which you don't get on an S40. You could fudge the crank pick up point to fool the ecu, but why bother. Try a few 0's in the first ignition column and it might pop a bit.

Re: Pop n Bang on aspirated engine
You can put negative timing in the main ignition map of s60 as thats what i run in the low kpa loads just above idle

Re: Pop n Bang on aspirated engine
Ok, yes but not unless you have map sensor, you can't do it on the main tps vs rpm

Re: Pop n Bang on aspirated engine
I'm wrong, (again) just tried it and you can go to -10 in the main tps vs rpm map. That has been changed sometime.

Re: Pop n Bang on aspirated engine
Yesterday , I tried with -10Deg but nothing and -10 is the max value so .....
May be it needs more fuel

Re: Pop n Bang on aspirated engine
No to pop and bang it needs to be lean
The flame front is slower mine pops iro afr 16.5 to 17.0
Even at 0 deg timing mine will pop it does your head in sometimes so my fuel has been turned off on overrun
To test this you can just lightly touch the throttle on overrun which will re introduce the fuel
