This Map is used to increase injector pulse width depending on the throttle acceleration. The
stock ECU may not compensate for quick changes in throttle position and may cause the motor
to run lean under heavy shifting or quick throttle movements. This Map will enable you to
add fuel under these conditions, for a limited amount of time. The Gain setting will control
how long the acceleration adjustment will be effective. Whatever number is set for the Gain
setting will determine the increments in which the additional fuel will decrease per injector
pulse.
For instance, if the gain is set at 1 and the acceleration map value is 40, the e-manage will add
40% injector pulse width and decrease it by 1% every time an injector fires. It will continue
decreasing by 1% until it reaches 0, which will take 40 injector pulses. If the gain is set at 0.5
percent, it will take 80 pulses for it to reach 0.
