I guys,
I have a question about tuning a stock FN2 with flashpro. Im running the Group N map, & I have started by calibrating the AFM, and the fuel trims are nice and flat, close to +/-1% almost all through the range at closed loop. So that part has been sorted.
My problem is that, when I go WOT, and it goes into open loop status, my car runs very rich, it goes from 12.8:1 corr. @ 4300 steadily down to 11.3:1 corr. @ 8200rpm. How can I change the fueling without causing the closed loop status when you change the fueling tables? I'm looking for 12.8-13:1 AF ratio.
I know the fueling depends heavily upon the MAF being calibrated, so that open loop fuel is calculated correctly, and it has been done. So what gives, why so rich?
Thanks in advance
