| - | In the direct access area of ECMLink, there is a table called InjBatteryAdj. This table is indexed by battery voltage and provides an appropriate deadtime adjustment at the corresponding voltage. As voltage drops, injector response changes. Less voltage almost results in a "slower" injector and the need for more deadtime. | + | In the direct access area of ECMLink, there is a table called InjBatteryAdj.
