16.32ms injection time is diagnostic limit, it will not log higher, no matter what (:

Anyone can confirm factor for MLHFM?

M3.8.3 AGU - Factor 0,125000, offset -200 - Max  673kg/h

M3.8.1 ABV - Factor 0,125000 - Max 989kg/h

Yes 4.98---> 988.63kg/h

It's not diagnostic limit, it's scaling limit IIRC in ECU. Or the scaling limit is close to that.

Scaling limit?

i know load max at 12,75ms (8bit, 255*0,05 = 12,75), but not sure what you mean with scaling?

Just took it for diagnostic as it will max at 16.32 but it will inject more (:


Throttle angle?
I noticed that my AGU only goes to 82,9% WOT (Using pedal and manuel on the throttle)
-Original throttle axis goes from 77% to 94% so it will interpolate between those columns! (Example: going from 8ms in 77% to 10ms in 94% will land you just under 9ms at WOT - 82,9%)

anyone else notice that? or is it just my throttle that's worn? (Changed axis to 82% so I could use the whole map)

Another question. According to the wideband in which areas kflf map do I make changes? From where to where is the area for idle, part load and wot? The changes must be made in each area separately by% to the desired?

For example is this right?

Your X-axis is wrong. (Factor 0,050000)

You log RPM, load and AFR (This is tricky as you probably log RPM and Load on PC and AFR by the gauge)

then you look at RPM and Load at the AFR you want to correct

Looking at my map:
Let say 6000RPM and 10ms you want to lower AFR, then increase 1,359 (35,9%) so it correct for more fuel.

log Load at Idle to find idle area (Pretty sure it's up to 1,5ms, maybe even up to 2ms)
and so on.

Thank you.For example how much need to increase 1,359 value if afr is lean?

Right now it inject 10ms*1,359 = 13,59ms (so in 13,59ms it inject fuel)

If you want to go leaner (Rise AFR) you need to decrese the value.

10ms * 1,300 = 13ms. (you inject less time = less fuel)

Ofcause you have other correction maps, so the real output will be different.
