Installed my FMIC, have some problems.
I just installed my greddy FMIC. Everything is in, and I went to give it a test run. I took it out on my road, got a little into boost, and noticed my gauges were messed up, so I got home, talked to a friend and found out I forgot to ground those front white grounds. Got those in, but now my car is running super rich, sounds like it's misfiring, and shakes weirdly. I took the UIM off, all the piping, and found out I accidently left the greddy plastic bag cover for the FMIC in one of the tubes, so it came up and hit the throttle body. 
None of the bag got torn off into the engine though, it was whole, just wedged up against the throttle plate.
I removed that, checked for any other debris, but it still runs like ****. Not sure what to do.

I had my Blitz FMIC installed just last week and had similar problems after starting the car up for the first time. Never had I seen my car idle so badly. It ran very rich and it too was misfiring heavily.
At this point I almost had a heart attack when I looked at my exhaust tip which was glowing very bright orange. I turned the car off and the bloke who installed my intercooler just said the car had to adjust to the new intake temp, and running the stock ecu, everything started to smooth out after the next few starts up. Thats my 2 cents.

Actually the stock ECU does make adjustments. That's why if you run a higher octane fuel (racing fuel) for higher boost levels you need to reset the ECU when returning to the normal street fuel as the computer will not adjust backwards.

Wrong they are capable of slight adjustments in timming. If you don't believe it run a high octane racing fuel in your tank and then run the next tank of fuel with your 93 octane fuel without resetting the ECU and see if you don't get some detonation.

It's normal for ECU's to self adjust (retard) timing on lower octane fuel.
However, very few cars advance timing with higher octane. To my knowledge, there is nothing in the FD which can sense octane to advance timing. The BMW later year M cars can advance timing based on octane (up to around 98).

certain "chips" that modify ECU settings for european cars tend to have capabilities to slightly advance/retard timing based on octane between 91 and 100...i dont know much about chips though, other than you solder them onto your turbocharged european car and they turn into a whole different car doubling your torque and other strange magical things...
