no maybe I should clarify a little. My friend who is a seasoned tuner (has tuned many cars for many years and has used A LOT of stand alone units) who prefers AEM management, he tunes with TPS as the main load (regardless of ITB, single TB, etc.) and on boosted cars he uses the MAP sensor as boost comp.
And I'm not too worried about ignition correction as much as if I were to use TPS as the mian load (according to the WIKI I need to scale the load points differently. But at what point and how do I make the MAP sensor add fueling to the TPS scaled VE table?
I'm not sure if using boost comp would be blending, I'm guessing it would be at a point where we start getting into positive pressure (boost).
I'm asking all this because it seems like an interesting way to tune a car, and would seem that in boosted applications would also mean that once the map is somewhat tuned, it wouldn't matter if the person ran 10, 20 or 30 psi, you would only need minor tweeks to the map.
