Designed for enthusiasts seeking improved drivability, performance, engine protection and tuning flexibility, this distributor delivers fully programmable ignition control via Bluetooth smartphone connectivity while retaining the iconic appearance of a classic Bosch motorsport distributor.
Specifically configured as a left-rotating distributor and designed for use with two 3-pin CDI (Capacitive Discharge Ignition) units, this system is ideally suited to twin-plug Porsche engines requiring precise ignition control under both naturally aspirated and turbocharged operating conditions.
What Does the Distributor Do?
The distributor is responsible for accurately delivering ignition signals to the spark plugs at precisely the correct moment throughout the engine's operating range.
In a twin-plug Porsche engine, the distributor controls:
- Spark timing
- Ignition advance curves
- Cylinder firing sequence
- Twin-plug ignition operation
- Engine starting performance
- Engine efficiency
- Throttle response
- Combustion quality
Accurate ignition timing is essential for extracting maximum performance while maintaining reliability and engine safety.
Why Upgrade to a Programmable Distributor?
Traditional mechanical distributors rely on fixed advance mechanisms that offer limited adjustment and tuning flexibility.
This modern programmable distributor provides:
- Fully programmable ignition maps
- Smartphone Bluetooth connectivity
- Boost-sensitive ignition control
- Vacuum advance functionality
- Rev limiter programming
- Integrated immobiliser system
- Improved engine protection
- Greater tuning precision
The result is significantly greater control over engine performance across all operating conditions.
