LOL!!
DL are you saying you and JMC have discovered basic engine timing theory?
Timing is, has and always will be affected by RPM and load (typically by referencing manifold vacuum)
Ever heard of little thing called a
vacuum advance unit used on old distributors?
(vacuum=more advance, more load=less vacuum therefore more load= less advance)
and vice versa!
Engines havnt changed, but the tools used to control ignition timing have!!
Maybe try combining your MAF adjustments with some different MAP (or BARO?) clamp settings DL...
OR
Pay someone like TC to do it for you... lol/jk ...
well sorta j/k... not trying to be a dick but "trial and error" piggyback tuning without being well-versed in basic engine theory could spell a formula for disaster!
