Review
Original map with 2bular exhaust on 6/3/06. Extremely badly mapped, with severely retarded ignition causing very poor throttle response, and compensated for cold running up to 80 deg, so since the engine had a 74 deg stat, it ran permanently in cold enriched state - wonder what the numbers might have been had it been carefully mapped. Took this engine to rollers for power run 17/11/09, found just by adding 15[!] deg ignition advance between 1500-3000 rpm the engine gained fantastic throttle response. Engine not mapped at this time [see other graph] but consensus that careful map would see power well into 220s.
