C.2 The Injector Drivers
The ECU uses switched injector drivers that can control the current passing through an
injector by switching the low side of the injector between ground and 12V while the injector
is open. When it is required that the injector be turned off, the low side of the injector is left
floating which will prevent any current from flowing in the coil.
The E6GMX has two current settings 4A Peak and 8 Amp Peak. The 4A Peak can control up
to 4 low impedance injectors or 8 high impedance injectors, whereas the 8A Peak setting
enables the ECU to control 8 low impedance or 16 high impedance injectors. Should you need
to drive more than 8 low impedance injectors or more than 16 high impedance injectors,
please contact your Haltech Dealer.

WARNING:
UNDER NO CIRCUMSTANCES SHOULD YOU MIX SATURATION
AND PEAK-AND-HOLD INJECTORS ON THE ONE DRIVER. THIS
WILL LEAD TO ERRATIC INJECTOR OPERATION.
