Had anyone ever thought or already implemented a closed loop mivec patch? Using backpressure ratio.

Emap map

20:20
22:21.5
24:23
26:24. 1.04: 12*
28:25 1.12: 5*
30:26 1.15: 0*

Something like that.. Would that make a whole lot more sense and ease of tuning ?

MIVEC is already closed loop. I dont understand the question unless you mean rather than have it target a crank degree value you want backpressure? Tuning it vs the crank degree values to keep backpressure low is the whole goal anyway but doesnt need to be done vs an EMAP.

I was just thinking instead of rpms and load : back pressure, would be more suitable in the calculation since that's what people try to eliminate .
(Edit; that doesn't sound 100% right but I was just thinkin aloud )


I thought it was open loop for some reason.


Basically whatever scale of back pressure was prevalent , a given mivec value would be associated.
