Symptoms of Fault

Distributor-related faults can present as difficult starting, uneven idling, intermittent misfiring, hesitation or stalling. Unsteady timing readings, excessive shaft movement, internal moisture or damaged cap contacts warrant inspection. These signs do not establish that the complete distributor needs replacement.

Why Replacement Matters

Mechanical wear or electrical deterioration can disrupt spark distribution and timing consistency. Inspect the cap, rotor, leads, plugs, wiring and associated ignition equipment before deciding which components need renewal. For a rebuild or ignition conversion, verify the clockwise drive requirement, HKZ arrangement and intended ignition settings before installation.

FAQs

Is this suitable for the 911 SC 3.0?
No. The supplied application specifically excludes that engine.

What ignition equipment does it require?
This version needs two three-pin HKZ units; check the existing installation before selecting it.

Can the ignition settings be changed by smartphone?
Yes. Bluetooth app access provides ignition-map programming, rev-limit adjustment and PIN-based immobiliser control.
