Tricky-Ricky Posted August 21, 2013 Share Posted August 21, 2013 Depends on ambient temps, could be anything from 10 on a frosty morning to 13-14 on a hot day, there is a sensor in the coolant system that tells the ECU what fuel trim to apply when cold and it will stay in the cold start map until a certain temp is achieved, hope your not giving it WOT when cold?
