Auto VE from scan on normal tune

[Behold]

Is there a way to do a VE alteration from a scan with LTFT on and DFCO on. It saves switching between tunes when I get a long journey last min......

I know that someone altered a tune o here for me when I had Them on but would like to know what I should filter on.... Do I need some extra PIDS?????

Thanks

Hi Antony,

Either way, DFCO can be left enabled if you filter out on EQIVRATIO going lean (leaner than 0.95 say).

When correcting the VE, the MAF must be disabled (to avoid contributing air from the wrong source), and vice-versa.
