Ok, x=rpmm etc. I assume the green corner is origin, and right hand rule for coordinate sys applies ...rpm toward us, load to right, and ms up.
16x16 map
load axis would be normalized (amm meas'd flow)/(wot VE based max at rpm)?
so if boost is 50% over stock, then at ea rpm, the right side max load limit for ms is likely hit before peak boost occurs. This implies thru mid and upper rpm range, the ms map is just the max load profile at the right.
At the far right, ms drops a lot at the higher rpms. Logically, this would coinside with oem APC boost taper. This shows why tweaked apc boxes that hold high boost thru rpms would have progressive lean-out.
any comments Ragnar? thanks for the info.
