Most advance the injection timing slightly by altering the boost pressure signal to the computer through the MAP sensor. Or so I've been told.

All Quad chips do timing. They can be modded for pressure only or with X2, a pressure only tune can be downloaded.

MAP signal cannot affect timing...

i had them all but the PowerPuck. Had 3 MP8's with problems. The EZ was the only one i found to be pleasing on a rail gauge and was stone reliable. The Quad XZT pressure only is good, but not adjustable. Dr P was good bit of pressure on the top end. The MP8 pressure ramp was pretty aggressive.

On the the thoroughbreddiesel site under MP-8 FAQ's it reads "since the map sensor thinks it is at different boost level it will add injection timing accordingly".

I think that is referring in a very confusing manner to the boost fooling of the MP8, the boost fooler makes the engine think it is as a higher(or lower, I honestly forget which one:thud:) boost level then it really is causing the motor to fuel harder down low. I have stacked my edge juice with my ramifier and I have heard no timing knock so I am fairly sure it does not advance timing.

When you add rail pressure it increases timming slightly, so any rail psi box increases timming just not enough that it should be a problem.
