Does the g/s need to be tuned to one hundredth of a gram? I find that I pick the nearest tenth of a gram on the curve. How much ram is used to to the interpellation with the larger values?

The curve lookup isn't the problem. The MS3 implementation calculates an internal lookup table that is used in the interrupt code on each sample - that is simply not possible on MS2.

How often is the MAF sample? Is it tied to crank angle or something? When I get more time at work I'd like to run a single on MAF and sampling at the same phase of the engine every cycle should give good results. It works quite well for the MAP values.
