Ignition Timing

Print

GENERAL INFORMATION



There is no conventional distributor for the DIS system. Instead, timing is controlled by the Powertrain Control Module (PCM) and/or the DIS ignition module. The PCM has the ability to advance or retard ignition timing for optimal engine performance. No timing adjustments are necessary or possible.
