gee youve got some knowledge mr sam!

i agree with your last statement there about the timing, tuning an N/A engine (or any engine for that matter) with only the fuel, is essntially a waste of time. or a means to an end.

this is why i dont understand how tuners can only take 1 or 2 hrs to tune engines, me and a mate have been fine tuning his megasquirt ecu (on a rotory) for months and months, getting every last bit of timing advance and getting the AFR's spot on. and it just keeps getting better and better....
