Tune-Up - 4 CYL: Distributor

All models are equipped with a breakerless electronic ignition system. On 924 models, Bosch Hall Effect distributor is used with an electronic idle stabilizer. 924 Turbo models have an electronic digital ignition timing control (DITC) system, using a flywheel sensor and a timing control unit.

944 models use a digital engine electronics (DME) system to control ignition and AFC fuel injection. DME system uses flywheel speed and reference sensors. Distributors on 924 Turbo and 944 models are used only to distribute the spark to the proper spark plug.
