I have TBI. My warm VE / accel enrich values are pretty dead on. When the motor is cold, it tends to go very lean and spit back up through the intake when I try to slowly take off from a stop. As it gets closer to operating temp, the issue goes away. I don't want to richen the WUE values too much because it already runs rich at cruise when warming up and would foul the plugs. Will retarding the timing when cold help the issue? By default, MegaTune advances the timing when cold.

Thanks!

ffb,

You probably want to increase the cold accel multiplier in the Accel Wizard. There is more on this here: http://www.megamanual.com/mt28.htm#tl
