Battery Voltage
The Haltech ECU uses intelligent fuel injection driver circuitry that compensates for changes in battery
voltage. As the battery voltage falls, the injectors will take longer to turn on and so reduce the effective
open time. To compensate, the ECU applies the Battery Voltage Map to increase the injector ‘on’ time as
the voltage drops. This map can also be considered as an injector dead time map.

This map should not be used to compensate for a deficient electrical charging system on a vehicle.
