^ Fuel trim | Fuel trim is an adaptive strategy that adjusts fuel injector pulse width (open time) to adapt to wear, defects, or changes in the system. There is a short term fuel trim STFT and a long term fuel trim LTFT strategy. | ^ Fuel trim | Fuel trim is an adaptive strategy that adjusts fuel injector pulse width (open time) to adapt to wear, defects, or changes in the system.
