Ugh, terrible experience.

Spent good chunk of the day figuring out why the engine wouldn't run... that was a simple connection problem.
Run the engine a little bit, runs rough. Start it again later, even more rough. Look at the battery voltage meter in megatune and its reading in the 9V range. The car doesn't have an alternator but that seems awfully low.
Also the engine doesn't want to turn over an more, also seems like battery may be dead.
Mess around with it some more... definite a burning electronics smell. Probing around shows that there is plenty of voltage. Appears to be the injector mosfets. I probe them when I turn the power on - they are definite turned on, and the gates are turned on... hrm. Go back to the injector driver, it's malfunctioning. So I read around on the internet, someone had this problem before, looks like its a power supply issue on the v2.2 boards. Then he mentions blowing 4 foot fireballs out the back because his injectors were full open. Hrmmm.....
Go out to the car, notice gasoline dripping out of my intake. Oh shoot. I was hydrolocking, engine is now full of gas.
Scarf down dinner as fast as I can, go outside, rip off some exhaust parts, pull the spark plugs, and turn the engine over by hand. Dump maybe half a gallon of gasoline all over the engine and the floor of the garage. Place smells like crap. It's 9PM. Running box fans at full blast - place smells like crap. Dunno how I am going to spend this night..... ugh.
