Haltech E11/E8 Instruction Manual
Direct Fire Multi-Coil Ignition (1 coil per cylinder)
Wire each ignition output to its corresponding coil with IGN1 output wired to cylinder 1’s coil/Ignitor, IGN2
output wired to cylinder 2’s coil/Ignitor etc. The firing order for ignition will be taken from the firing order
that is specified in the Main Setup in the programming software. Its important to note the difference in
wiring order between direct fire and wasted spark – in direct fire mode the ECU will fire the ignition outputs
according to the firing order entered into the software where as in wasted spark mode the ECU will
disregard what is in the software and fire the ignition outputs in the order of the Haltech ignition output (ie
IGN 1, IGN2, IGN3 etc.) Note: E8 ECU is only capable of driving 4 individual coil channels, and can
therefore only do direct fire on a 4 (or less) cylinder engine.
