Okay this is for everyone running FI on a 3V:
YES!!! YOU HAVE TO LET THESE CARS WARM UP TO 180* (4-5min) BEFORE YOU DRIVE HARD OR IT WILL BUCK AND MISS BECAUSE YOUR ECU IS NOT ABLE TO SUPPLY THE PROPER FUELING DURING COLD START FOR DRIVING DUE TO YOUR WOT FUEL TRIM AND YOU ARE RUNNING LEAN!!!!!!!!
I had my tune tweaked at Stang-Hi, I think he adjusted the fans not to come on until the engine is 180* to aid in initial warm-up, since these cars make the best power between 180-210*, and it's cold here. I had some problems that were linked to the car never really reaching operating temp (could have been what kept killing of the HT0s, but never had that prob with the Brisks)...we swapped back to a stock 180* thermostat and tweaked the tune and the car has been great ever since. It did seem like my canned KB tune did pretty much keep the fans on all the time.
