The pops and bangs is controlled through using about 5-10% of throttle above 2,500RPM doing high RPM overrun (So your using fuel, but not enough to for the required throttle applcation/fuel injected to match cars current RPM)
I have got this done to a T now
If you have Cruise Control console, it techincally means you have different ECU with more "memory".
So I can only have 1 map, if you have CC you can have 5 maps I believe, allowing you to swap between different map settings, 1 eco, 1 pops and bangs etc etc.
You would have to PM Mark@AbbeyMS (that's even if he would share that information.)
Cheers for the info will be looking into that
