In the never ending quest for the perfect map for my CBR I'm now on map #5 and still no end to this journey in sight. No two of the maps appear to be the same, most are not even close to each other. Which one is right and which ones are wrong? Or are they all right or all wrong? Does it even make any difference?
If you are happy with the way your bike is running, if it doesn't foul plugs or shoot 3 foot flames out the arse end or run so hot it seizes up is all well? Some of my maps are obvious DJ autotune specials with injector duty cycles all over the grid from negative to positive values. No human mind could make sense out of the data, they look random and chaotic. Other maps are obviously put together with some kind of "formula" the tuner has developed and have a geometric neatness to the way the cells are mapped. Which method is best? Does the A/F ratio in an engine follow an orderly geometric or linear progression as rpm and throttle positions change or is it indeed random and chaotic as resonance in the intake and exhaust tuning dictate changes in volumetric efficiency and thus A/F? One school of thought says one thing and believes they're right, another insists it's another way. Dyno Jet says the holy grail is an AFR between 12.7 and 13.2 and their auto tune software relentlessly chases that parameter. I still hold to the opinion that the best way is a combination of baseline mapping under load on a dyno and then real world adjustments made out on the road to smooth things out and optimize the mapping.
