ThanksCan it self learn to the point of making a street friendly good gas mileage daily driver?

An external engine management system (Fast,BS3) is much better than running the stock abbaccus,even with all the add ons.Think of a 12" dia circle and points at every .5" distance around the circle.Now draw lines through every point tangent to the circle.This represents the control resolution of the stock computer.This also represents stock control resolution with respect to all six cylinders.Draw six circles just like the first and place points on all the circles .25" distance around each of the circles.The single circle represents "abbaccus control" using the stock computer (8 bit motorola 68000) for all 6 cylinder air/fuel control events.The 6 circles represent the air/fuel control events for six one cylinder engines operating in firing sequence from a Fast.This sequential individual control provides specific air fuel tables for each cylinder.Take the 6 circles and lay them all on top of each other and this illustrates the control resolution of the Fast compared to the stock computer.The Fast is much quicker than the stock computer.Just the fact that individual,sequential, greater resolution air fuel tables can be managed can keep a car further away from catastrophic destruction via detonation if crazy notions are avoided.Other benefits result from a fast once you get going with it.An external engine management system is expensive,but engine rebuilds are much more expensive.
Forgot to mention there are a few gutsy/crazy racers running stock short blocks (no forged crank,no caps,no girdle) and surviving in competition with external engine management systems.Contro l of firing parameters saves engines (asside from fatique).
