Runnin rich when cold outside
I HAVE A 355 TPI THAT I JUST BUILT AND IM TRYING TO TUNE OPEN LOOP VE TABLES. THE PROBLEM IS THAT IN THE MORNING WHEN ITS LIKE 40 DEGREES MY CAR RUNS REALLY RICH AND IN THE AFTERNOON WHEN ITS 70 ITS NOT RICH. WHAT DO I NEED TO CHANGE? I DIDNT RELOCATE MY MAT SENSOR AND IM RUNNING 730 ECM WITH MODDED AUJP BIN AND 8D XDF. ANY HELP WOULD BE GREAT.

Most likely want to adjust the open loop AFR vs CTS table:
; OPEN LOOP AIR/FUEL PCT CHANGE vs COOLANT
At: $45E
Remember that the values are a change in percentage.

Re: Runnin rich when cold outside
WHAT ABOUT THE MAT TABLES SHOULD I DO ANYTHING WITH THOSE? i FORGOT TO MENTION THAT I HAVE DONE THE COOLANT BYPASS ON THE THROTTLE BODY. I HAVE MESSED WITH THAT TABLE BUT EVEN AFTER THE CAR HAS WARMED UP ITS STILL RUNNING RICH WHEN ITS COLD OUTSIDE. THEN WHEN THE TEMP WARMS UP OUTSIDE IT LEANS OUT SOME.
