Well done, I know from experience that its no fun trying to show that table on a web forum.

Well if that is the ignition map, then I would say its actually safely conservative, especially as the revs climb and the ignition doesn't, a bit lazy and ignoring VE and piston speed, but certainly safe from a det point of view, if perhaps not EGT, but suitable fueling will combat EGT so that is irrelevent.

How come Tony worked it out to be so different on his screen?
I am a little lost now... Maybe you have been sent a different map Mike?
