    hard to start when cold. 5.3l 4l80E E-85

    is there any areas I should be looking in the tune that would fix this problem.
    on the 1st start of the day it takes 3 or 4 attempts to start. the 1st attempt it wont even fire. the second attempt it will briefly start then die right away. the 3rd attempt it will usually start right up. after its warmed up theres no more issues starting. on really cold Michigan day say 15*F it takes 8 or 9 trys. weird thing is when its running it always smells rich but wide band is showing 14.7 im sure its still setup for gasoline.


    this is a 2 bar S.D. tune and i do have a 76mm turbo.

    i was getting help but went into the hospital and lost track of my help. cancer is a B.

    i will post a video tomorrow of what it dose also and log it at the same time. to add some visual.

    Sorry for video quality. the sound on it stinks. it makes my motor sound like a sewing machine even though it not. I think the exhaust makes the microphone clip.
