Rennen Camshaft Position Sensor for Rennen by JSR Individual Barrel Throttle Body Upgrades

The Rennen Camshaft Position Sensor (CMP Sensor) is a critical engine management component designed specifically for use with Rennen by JSR Individual Barrel Throttle Body (ITB) upgrades. Working alongside the Crankshaft Position Sensor, the camshaft sensor provides the ECU with precise information regarding camshaft position and engine cycle synchronisation, allowing modern engine management systems to control fuel injection and ignition timing with maximum accuracy.

Fits:

• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50

When upgrading a Porsche engine to Rennen by JSR Barrel ITBs and standalone engine management, accurate engine position data becomes essential. While the crankshaft sensor identifies engine speed and crank position, the camshaft position sensor tells the ECU exactly which cylinder is on its firing cycle. This information allows advanced ECU strategies such as sequential fuel injection and cylinder-specific ignition mapping.

For high-performance road, track and motorsport Porsche engines, the camshaft position sensor is a key component in unlocking the full potential of an Individual Throttle Body conversion.

What Does a Camshaft Position Sensor Do?

The camshaft position sensor continuously monitors the position of the camshaft and transmits this information to the ECU.

The ECU uses this data to determine:

• Cylinder identification
• Camshaft position
• Engine cycle synchronisation
• Sequential fuel injection timing
• Ignition event timing
• Engine start-up strategy
• Advanced engine management functions

A properly functioning camshaft sensor helps provide:

• Accurate fuel delivery
• Improved ignition control
• Faster engine starting
• Enhanced throttle response
• Stable idle quality
• Improved drivability
• Greater tuning precision

The sensor enables the ECU to know exactly where the engine is within its operating cycle.

Why Is a Camshaft Position Sensor Essential for ITB Conversions?

Rennen by JSR Barrel Throttle Body systems are designed to maximise engine performance and responsiveness. To fully exploit these benefits, modern programmable engine management systems require highly accurate engine position information.

The camshaft position sensor allows:

• Sequential fuel injection operation
• Cylinder-specific ignition timing
• Improved cold-start performance
• Enhanced fuel economy
• Smoother idle characteristics
• More precise tuning control
• Improved emissions control where applicable

Without a camshaft position sensor, many ECUs are forced to operate in less sophisticated batch-fire fuel injection modes, reducing the overall refinement and efficiency of the engine.
