    Basically the car will start when it is cold fine, but once it heats up it wont start unless I give it some extra gas.

    I am using the SCT pro racer software to tune.

    I am looking for the area that will best fix this issue.

    Not sure if it is a hot start fuel issue, or hot start air issue.

    Any advice would be helpful!

    So i tried increasing the Crank fuel pulse width. from .00199 to .00450 which was the value for 70deg temp.
    Drove till it was warm and.... shut the car off, would not start.

    Figured that I should be lowering the number instead of raising it.

    Default was .00169 (I took 10% out) 210 deg

    Car started, still had get give it a little gas. I belive the more I lower this the better the car will start.

    I will post my progress next weekend.
