Guys,
I have s 2019 F150 using a Roush Supercharger Kit from a Mustang, LiTuning return style fuel system, 1000cc FIC injectors running E85. ECU forces a very low pulse width at all times, meaning, idle is perfect but as I start accelerating will go lean as even manifold press, fuel press both PI and DI are climbing a close to 1.0ms pulse is commanded.
Tune is on a Roush (Mustang) file that reads the 2 BAR MAP and Baro well, injector characterization is done with return style specs, fuel pump secondary monitor disabled.
If anyone would share some light, please!
Thanks!
