[QUOTE="C5Howie, post: 8549, member: 389"] Adaptive strategy systems can actually learn from past experience,it can adjust based on driving habits ambient conditions and for fatigue of vehicle components. When a computer has been disconnected removed or replaced there will be a short re learn period approx 5 miles of driving,during this time you may notice a surge or a high idle,loss of power. Most strategies have two parts long and short term fuel trim. Short term is the one more affected by this interruption of power and the long term is based on input from the short term. On older vehicle systems OBD1 you had to follow various re learn procedures that usually involved the checking or adjustment of various sensors. On later model vehicles the procedure is simply drive cycles,ie the first 5 mile trip is usually enough time to make any noticeable adjustments unless major changes have been made to the engine,then you better go see Manny@ECP [/QUOTE]
