have you adjusted fn1052 the VE correction table?

No, sorry, not familiar with that table. Does it go by another name or number by chance?

I got curious and downloaded your latest 2023 definition and sure enough the FN1052 table popped up. But that version also has the unscaled views of the fuel and MAF data, which didn't appear to be correct or even close. I prefer just leaving it scaled the way I'm used to seeing it over the years by using earlier definition FBGIO_200510. I tried changing the scaling percent to 1 as directed in the hi-slope comments, but that didn't work out right. So I took a random value from the MAF transfer FN036 and divided it by the previous value and then multiplied the scaling percentage value by that ratio and that got the MAF, injector slopes and breakpoint back to what I had previously using the 2020 version of the definition. Not sure the comments in the 2023 definition do a good job of explaining how to back out of the unscaled view. But I got the scaled view of injector data, MAF, manifold volume, SARCH correct again regardless. I haven't tried to load this into the QH yet to see if runs the same before I mess with FN1052.

why are you changing values?

the first thing you need to do is put in your actual injector high slope

then all else is fine and will display correctly.
