If possible due to your home location, a reprogram of the ECM would be a big help with glowing pipes and performance.
Unfortunately the ECU is locked so although you can use the S&S ProTune software to look at what's going on you can't save any changes.
I was told yesterday by Marcassus Sport that you cannot have the new factory firmware flashed onto the ECU unless you have a cooling fan fitted, which I don't. To try and reduce the pinking. I have therefore ordered 3 x 500ml bottles of Millers CVL Turbo octane booster as an experiment.
When I was running a Ralt RT40 F2 car in the European Hill Climb with a very high compression Hart engine, I used to order 130/145 octane "Purple" Avgas in 205L drums from Sweden and then add Toluene, Aniline and Furfuran to that but that is not a cheap fuel. 16 years ago it was working out at around £2.50 per litre. You were supposed to run pump fuel from 1994 onwards but none of the F2 cars with either BMW M10/12 or Hart engines were doing that. Nobody ever asked me for a fuel sample in 10 years but when I stopped in 2000, apparently the authorities were muttering about getting stricter.
