The problem is, the Predator adjusts spark and PE
but has no ability to address airflow calibrations. If
you (say) are a bit lean on the speed density side or
you could stand to have the PE MAP threshold a little
bit lower, so sorry, too bad.
It also wants to adjust spark by a single scaling, while
you might be able to stand more WOT spark but not
so much in the lower RPM, mid-MAP range, or whatever.
One size fits all. As long as you like a muu-muu type fit.
You can have things tuned well for steady state based
on MAF, PE and dialed-in spark but still have annoying
things go on during transient operation. I know this.
It's one of the things that made me give up on the
Predator and get the more broadly capable tool.
