Rennen Throttle Position Sensor (TPS) for Rennen by JSR Individual Barrel Throttle Body Upgrades

The Rennen Throttle Position Sensor (TPS) is a critical engine management component designed specifically for use with Rennen by JSR Individual Barrel Throttle Body (ITB) upgrades. Mounted directly to the throttle assembly, the TPS continuously measures throttle opening angle and relays this information to the engine control unit (ECU), allowing precise fuel and ignition calculations throughout the engine's operating range.

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
  • Porsche 964 (911) C2 1989-93
  • Porsche 964 (911) C4 1989-93
  • Porsche 964 (911) RS 3.6L 1991-93
  • Porsche 964 (911) RS 3.8L 1991-93

When upgrading a Porsche engine to Individual Barrel Throttle Bodies, accurate throttle position data becomes even more important. The instantaneous airflow characteristics of ITBs demand rapid ECU response, and the TPS provides the critical information required to deliver smooth drivability, sharp throttle response and maximum performance.

Whether you're building a fast road Porsche, a track day machine or a dedicated motorsport engine, the TPS is an essential component in achieving a professional and properly calibrated ITB installation.

What Does a Throttle Position Sensor Do?

The Throttle Position Sensor measures the exact position of the throttle barrels and communicates this information directly to the ECU.

The ECU uses this data to determine:

  • Throttle opening percentage
  • Driver demand
  • Acceleration enrichment requirements
  • Ignition timing adjustments
  • Fuel delivery calculations
  • Deceleration fuel cut strategies
  • Idle and part-throttle control

A properly functioning TPS helps provide:

  • Instant throttle response
  • Accurate fuel mapping
  • Smooth acceleration
  • Stable idle quality
  • Improved drivability
  • Enhanced engine performance
  • Reliable ECU operation

Without accurate throttle position data, modern engine management systems cannot react correctly to driver inputs.

Why Is a TPS Essential for ITB Conversions?

Individual Barrel Throttle Bodies dramatically improve airflow and engine response, but they also require more precise engine management control.

Unlike traditional airflow-restricted intake systems, ITBs allow airflow to increase almost instantly as the throttle opens. The ECU therefore relies heavily on TPS input to determine fuel and ignition requirements during rapid throttle movements.

The TPS allows:

  • Accurate throttle-based load calculations
  • Faster ECU response times
  • Improved transient fueling
  • Smoother acceleration
  • Better throttle modulation
  • Enhanced drivability
  • More accurate engine calibration

Without a TPS, an ITB-equipped engine can suffer from hesitation, poor throttle transitions and inconsistent performance.

Why Are Barrel ITB Upgrades So Popular?

Rennen by JSR Barrel Throttle Bodies are engineered to maximise airflow while delivering a true motorsport-inspired driving experience.

Benefits include:

  • Instant throttle response
  • Increased airflow efficiency
  • Improved engine breathing
  • Enhanced power potential
  • Greater tuning flexibility
  • Exceptional induction sound
  • Improved driver engagement
  • Stunning engine bay appearance

When combined with a correctly calibrated ECU, MAP sensor and TPS, the result is an engine that delivers exceptional responsiveness and performance.

Why Choose the Rennen TPS?

Developed specifically for Rennen by JSR ITB applications, this sensor delivers the accuracy and reliability required for professional-level ECU calibration and performance tuning.

Benefits include:

  • Accurate throttle position measurement
  • Compatible with Rennen by JSR Barrel ITBs
  • Supports standalone ECU systems
  • Improves tuning precision
  • Enhances throttle response
  • Supports motorsport and fast road applications
  • Reliable long-term performance
  • Essential for modern EFI engine management
