ECMlink Airflow help, log attached

Here is a log of a 3rd gear pull. My boostest is not matching my map sensor and can't really figure out why because i'm also logging my lc1 and it is matching the wbfactor and i'm getting a very close to 12.0 afr that i am commanding. Maybe someone can shed some light on what may be going on.

At 5500 RPMs you are ~11psi yet the ECU thinks you are ~23.5psi. Looking at your MAFRaw(2400Hz) you are at +29.7. I understand you are trying to match your true AFRs to your AFRatioEST but you also need to match your injectors in as well.

IMO, I would zero out your MAFComp anything over idle and richen up your Global Fuel. You wanna get your Boost/BoostEst lined up near 5500 RPMs(MAFComp table) while making sure your true AFRs stay near AFRatioEST(Global fuel).

How much change you think it's gonna take on global fuel as a start? I'm trying to learn, i posted in more detail on link forums. I guess i wasn't thinking about inj cause v3 calculates 2150's at -79.3. I thought i was getting very close because my direct access openloopmaxoct table i'm asking for 12.0 and that's very close to what i am getting. Now it seems i'm no where in the ballpark of close as changing that global will affect everything from startup, part throttle all the way to wot. Also when i start to change my global wouldn't the curve of the mafcomp stay the same just at a lower place on the graph? Seems like it might not be wise to 0 but to maybe just shift down in scale?

Im sorry I dont. Just off the top of my head Im thinking if you are taking away 30% in the airflow you should add it right back with fuel. 2150-30% = 1505. Maybe to be safe enter the value for 1450cc(-69.1)?

Honestly I would turn the boost way down and try that. Hopefully someone else may chime in and give you something better than what I just rambled on about .

I have done similar to this in that my 1150s are dialed in near 950s to get my BoostEst and AFRatioEST lined up with minimal work.
