There wasn't a turbo added at the same time as the MS was there? A turbo getting too much oil or with a blown seal will smoke.

If there's nothing being left out of the story I'd take the radiator cap off, let the car idle a few minutes, watch for bubbles in the coolant and see if the smoke clears up. No bubbles and smoke clears up then it's fixed. Bubbles and it keeps smoking then I'd look toward the headgasket.

Sorry to disappoint many of you, the head gasket was not blown. After running it for a few minutes the smoke turned from thick white to water vapor and then to nothing. It looks like someone dumped a full Poland springs water bottle behind my tail pipe. The car seems to running decent for a few minutes then tacks up to around 3000 which I'm not comfortable with because of how its only on the basemap, so I kill it also my O2 sensor is giving bad readings because of how black its getting so the fuel maps need some work there. Also the map reads very low, around 30 kpa. Spark is as close as I could get to 10 degrees. I will attach a few data logs I took and maybe a picture later. Thanks to every one who helped

Yes my car is filthy and yes that is my noob sauce spilling out the tail pipe

30kpa seems about right at idle I think.

How high does it idle before it warms up? You may have a leak on the intake manifold, that'll give you a high and uncontrollable idle. Check around for an open vacuum line or port.

Awesome to hear that it's coming together, I certainly don't think anyone is routing for failure. I had a hell of a time getting my first car running right on megasquirt, there's a steep learning curve but you'll get there.

It idles fairly decent at about 1900 rpm when its cold. hits decent afrs. I know before I did the ecu there was a vacum leak coming from one of the injectors that I never really bothered to fix because I knew I would be in there soon enough but on the stock ecu it was a rising and falling idle not a constant rise. But I'll throw my new injectors in tomorrow. Check if they flow and put them in. I had an airfilter that was on there for a temporary thing that I found was actually hurting the airflow, pulled it off and it seemed like it ran better. Also my coolant was reading at about 230 degrees when it was warmed up, what should it be? I was thinking around 200-220 right?

Gasoline is a hydrocarbon, which means it's made up of C and H. When burning it, the Hs and Cs break apart and combine with Oxygen (O2) to make H2O and CO2. CO2 is a colorless, odorless gas, so it just vanishes out the tailpipe, but H2O is water or in this case steam.

So steam comes out of the exhaust valves and flows through the exhaust system. If the exhaust system is cold (as in, below 212F) the steam condenses against it, turning back to liquid and puddling in the exhaust. Gas pressure pushes it out.

That's why you get water coming out of the tailpipe. Any car will do it if you leave it idling for 15-20 minutes after starting it from cold.

Should be around 200 degrees warm with stock thermostat.
