Engine/Transmission (1998.5 - 2002) CTD fuel map

[Hohn]

Just something I was thinking about.



I know that the CTD determines fuel injection load based on RPM and boost and stuff like that. But if you could build max boost @ 2100RPM, would you be using less, more, or the same amount of fuel (per injection event) at 2800 rpm?



When the CPC boxes say they are injecting 100% @3psi-- 100% of what?? Is that out of the max through the WHOLE rpm range, or just at that RPM?



How does a wire tap box alter the map??





Can anyone explain to me more about the injection map and how it is set up??

I guess what I am asking is if someone can explain exactly how the VP44 calculates how much fuel to inject? How does the APPS input affect this?



I ask because with the EZ on most aggressive, there is a HUGE difference in response vs one of the lower settings. This is with stock injectors (for now-- B-day is coming up)
