is it better to have the rpm match that of the spark or different to spark table ???

or dont it matter ??

i would have thought of tuneing side it would be easyer to match the rpm ??

It doesn't matter. You really just want to set your RPMs to where you need the greatest control or granularity fo that function. For fuel it may be different than spark, maybe not. Id depends on your setup.

When you first start tuning its best to have them match. Later when you are fine tuning your ve table you may find you need to move a few of the rpm and kpa bins around to get finer control at a particular load/RPM, usually around your torque peak.
