    Smoke on Immediate Hot Start

    My situation is this, if I am driving, especially driving hard, then I come to a stop and idle, the car will create a nice cloud of white smoke and then it will go away. It also does it if the car dies and I restart it, smoke. I am pretty sure it is loading up with fuel. I am running a vacuum pump, no PCV system. I am confident there is no oil issue so let's just attack fuel issues. Ford Green Tops.

    I am not sure what I have wrong so I am posting my tune. I have edited the Injector timing as well, which seemed to help. I am also idling in open loop at stoich.... I have not touched most of the idle tables (only RAF, RPM, obvious/popular ones).

    Any ideas? This is an embarrasing issue more than anything else. How great is it to be cruising around in a Z06 with a 408ci motor and then everyone gets to see it smoking like a clapped out 70's El Camino.

    mine was doing this and it was my idle airflow. If your loading up with that much fuel then something is set up wrong. I can't look at your tune on this computer but I'll take a look later and see if I can find anything. Maybe someone with more experiance will help.

    I hope so, lol. My plugs might even be too cold for all I know. I have Dart heads, which take a gasket seated plug so NGKs are out. no cats.

    I can't open your files. You must be using the new beta version or it's a corrupt file
