cold starts

i checked the last two pages for a thread on this and couldnt find one. its been getting chilly out and the truck is starting to act a little different on start-up. basically cranks longer (expected), then it pours white smoke at idle. you would think its a cammed out, non-street legal pullin truck it smokes so much. it smokes for a few minutes then it just hazes white smoke till it fully warmed up. that paticular morning was our first frost.

is this normal? and when should i start plugging my truck in?

Start pluggin it in whenever you want that instant heater.
I think the smoke is normal till warm up on some trucks...seems like alot of em do it but mine doesn't. Do you have the latest reflash to your PCM? theres a cold start fix version 2 that the dealer can do for it if it hasn't been done.

Your tuned up so that white smoke till warmup is just extra fuel that is unburnt Like CHenry said when it gets cold at night plug her in will only help on startups and the truck will warm up faster.

Your tuner can give you a cold start tune, but it will be less powerful. I don't like the way mine is starting even at 45-50 degrees. I will most likely go for the cold fix and sacrifice power for smooth starts during the winter months.

thanks for that info guys i will most likley start pluggin her in soon. i have a sct tuned by dj's, my daily driver tune is a street smoke tune. it may have a cold fix on it because when i first start it up it will idle slowly with only a little smoke then the rpm's will increase every few minutes and the smoke starts pourin.?

i have recently started plugging the truck in. the starts are much easier, but theres still a good amount of white smoke, not as much as these pics though. here are some pictures of a recent cold start when the truck was not plugged in. heres the white smoke i was talkin about. look normal, lol? i'm pretty sure i have the cold fix on this tune. it starts out at normal idle then picks up after a few minutes and doesnt go back to normal untill i press the brake.

initial start-up

high idle picking up
