Hey All,
I just finished tuning a C7Z A8 with an F1X. I feel the cam was not optimal, but we made about 1000whp through the auto. The vehicle is using a supplemental fuel system through 8 port injectors in the procharger intake manifold. The supplemental is done through it's own computer, and here is the problem :
When the vehicle rev limits, OR changes gears during WOT, it turns off the fuel injectors. The port injectors at wot will still be flowing and this will cause a terribly lean condition. How can I make sure that the torque management event for the shift, or limiter will only use spark, and not fuel cut? Any help is much appreciated.
I have not tried to drive the car yet during these conditions as I'm worried that even one event can cause damage.
