ok here is the story. The car is a 97 eclipse gst with following mods:
b16g
afc
550cc inj
exhaust
datalogger,egt

Tonight I when to the track to run it for the first time since i put the injectors. In I had tuned the lo thrl on the car, but not yet on the hi. I put 2 gallons of 110 octane mixed with a quarter tank of 93 octane with boost @13. Started my first run and after i shifted into second gear my car just died. I thought i blew a hose or something, but the car does not idle (have to hold gas to keep from dying). The car is getting way too much gas or something, my spark plugs keep on getting carbon on them. My first thoughts was that the gas had something to do with it so i put 5 gallons of 87 octane to bring the octane down and changed my plugs. Started it up ran better for about a minute then started to smoke black pretty bad and you the gas smell is very strong. I was getting the following check engine codes:

Engine temperature circuit
intake Air temp circuit
manifold absolute pressure/barometric circuit

the air temp won't even show up on the datalogger and the coolant temp is -40f.

I've tried everything that i know of and i need help before i become a nervous wreck. The car ran fine before i went out to the track. I didn't blow anything up did I?
 
when I took my car into the shop to get the timing belt replaced after I bent some valves, it started doing the same thing and showing the same codes as yours. It also ran rich as a black rap star. A new ECU fixed my problem, try swapping it with a friend's ECU and see if that fixes it.
 
That's alot of fuel for only 13psi. 93 octane is more then enough for that little amount of boost. Try resetting your ecu by unplugging the battery for a few minutes.
 
yes thast way toomuch fuel , get your Hi setting tuned please if you havent done any damage.....I just put most of the stuff you put in tuned low throttle and took it out, at 4000 if feels like i hit a brick wall , not fuel cut but becausei wasnt tuned in high....we just leaned outmy high to 9 straight across for the time being till we can get the loggeron it. good luck
 
well i took off my o2 sensor and it was covered with carbon, i cleaned it and put it back in. The codes are gone, but my datalogger is still showing that i'm getting a coolant and air intake temp of -40f could this be a problem with the mas?
