Hmmm, I never notice that until you pointed it out. Mine does the same thing.
I had be dividing by 150,000,000 to get AFR data that seemed to match what the dash gauge would display. The 2 billion seems to put out lambda, which is great... BUT, looking over one of my logs from the track.. If it is set at 150 million, my afr's show what should equate to .80 lambda based on the fuels stoich value. If I set it to 2 billion, it shows .82 lambda in that same area. SOOOOOOO, somethings not accurate, gonna have to put a separate wideband on this thing now and see what I can figure out.
My guess and hope is that this PID is trying to spit out the AFR data like the dash gauge displays. So it might take some backwards math to make it display lambda correctly.. Id rather work in lambda anyway.
For what its worth, during my track outing, we ran VP MS109 fuel. its Stoich is 13.41. When that was changed in the tune, the dash display matched the wideband log divided by 150 million almost spot on.
Gonna have to give the 150mil a shot. Seeing as I'm targeting .87, if I'm actually at .89...that could be bad news bears. I have logged w/ my sct and the data seems to coincide rather closely, I stretch out 3 sometimes 4 decimal points to verify the data. I have same tune on back to back runs sct @ .860-.865 and hpt showing .865-.875.
E85 btw and I've also got egt on cyl 8, highest I've seen is 1200 @ wot, I see higher egt's doing step logs than I do during a wot pull.
