Does it run if you put in the right linear/offset for the 1-bar sensor?

I didn’t even attempt it I just went a got sensor. But everything seems to work well with a short run around the block.
i ran it and it seems to really thin out in power enrichmentOriginally Posted by SiriusC1024
Idk. It should be coming out of PE at 70kPa, 51% tps. It's staying on during decel.
Fuel matches commanded perfectly until the point where it should be coming out of PE.
Maybe try the SD12 file I made for you instead of the FlexFuel one that cobbled code from like 3 different tunes? Apply the 2bar OS to it and modify necessary tables.
same thing no change from what i can tell. you dont think we need to add more fuel to power enrichment?

No. Those areas were mapped out with LTFT+STFT. Need to figure out why it's not coming out of PE.
Disable Fuel>Temperature Control>COT.
thoughts?
That's more like it. First was taking care of PE. Now re-tune VE.
which table do i use to tune the ve? do i use the gen3 ve eq 2 bar table? add the red and minus the green numbers? also with these injectors it seems peppy or very responsive.

First make sure fuel data matches reg config. Vacuum referenced reg or not?
no vacuum constant 58 psi I switched all the fuel data over to sd12

Ok then make adjustments like you were saying. lmk if you need help.
will tuning the supercharger be same?
Yes, but you'll need to use a wideband for most of it. LTFT should be disabled and cleared when tuning the wideband portion NA or FI.
that maybe where i messed up i was about to ask if i should turn off LTFTs and clear when doing this tune
Fueling is looking pretty good. Keep at it. I enable LTFT for the narrowband portion. Disable for wideband because positive LTFT's carry over.
how do i know when it's good? because i don't think it going to be picture perfect.?

It's close enough. One thing as a final touch is to do a lot of varied driving and let the LTFT's populate. Don't have to be logging as they save on the ECU. Later you'll have to log to hit the cells and reveal them. %-half the LTFT to the VE table. Interpolate/extrapolate the trend.
