My FAST XFI 2.0
My A/F target ratio is set to 15.86, and the actual A/F ratio is 15.86 at idle. How do I change this?
I looked into the online manual; and found the table I need to adjust; TARGET AIR/FUEL RATIO vs RPM and MAP. I can't find this table, on the C-COM software. BTW I am set to SPEED DENSITY.
So how do I find this table, are how do I reset the A/F ratio to idle the car richer.

I have briefly seen the fast tables I believe it was based off the gen 7 dfi which I have. can you post photos of the table options you have? are you tning with a wideband? (assuming yes). On the Gen 7 dfi there is a table showing map vs VE, this is the fueling table. If I can see what youre looking at Id be happy to try and help if I can

I bought mine from Dan White Racing, with his adapter that allowed me to plug into the stock harness.
Again a little dusty, showing the FAST XFI with the Dan White adaptor, and the Holly HSR.
