This is at least how I understood a while back.

anyway STFT is what I look at and care about since like you said it pretty much sums up whether we are ok or not fueling wise and also how far of not being OK
Gotcha, makes sense.

So clearly my LPFP is getting its ass kicked, my question is, how much? The rest of the log (AFRs, timing corr., timing, boost) look pretty damn good IMO, so is my low pressure pump getting beat on to a point where this map cannot be run safely? If so I need a walbro asap, because this map blows Stg2+ out of the water.
