The thing is, the fuel DOESN'T burn at a constant rate. Changes in RPM, Boost, Ambient Temp, Fuel Temp, ICP, and others all change the burn rate of the fuel because the temperature of the compressed air and injected fuel all change. Even just a simple increase in ICP will change when and how rapidly the fuel will burn.

Sheesh, I was thinking that all along there was a 1 constant something in all this.. WAIT! I know it what it is. the one thing that is constant is that nothing is constant!!!!

well in any case it finally looks like my MPG mods are making some improvement if My lie-o-meter has anything to say about it....
I am using the 80HP to build some MPG tunes, would there be a better base map to build from. I made the changes u mentioned earlier in the thread... I am really concentrating on the low boost, low APP area for running on the freeway as I like the get up an go on the 80 off the line. it has not seemed to affect that part of it thus far which is good...
