Does anyone have any pointers on tuning transient fuel on Mustangs? I've got a serious lean tip-in issue when the engine is cold that I have been fighting with for a while. I have managed to tune out my lean tip-in when the engine is hot. Throttle is crisp and responsive only if the motor is hot. This goes hand-in-hand with rich tip-out. I've tried adding to the startup tables but it doesn't seem to help. I also can't figure out if all of the decel stuff needs to be increased or decreased to reduce tip-out fuel. I believe I have a grasp of x-tau transient fueling theory but I'm still scratching my head. All mods are in sig. Any pointers are appreciated.
