Adapt Motorsport electronic individual throttle body (eITB) kit for the Porsche 964 and 993. Six individual throttles are operated as two independently controlled cylinder banks by a modern drive-by-wire engine-management system.
Fits
What This Product Does
The eITB assembly replaces conventional pedal cables and cross-bank throttle linkages with direct electronic actuation. A compatible aftermarket ECU can regulate each bank, control idle through the throttle motors and tailor throttle opening to pedal position and operating conditions.
Functions
- Controls six individual throttles using two independent drive-by-wire motors
- Permits ECU calibration of pedal response and throttle sensitivity
- Manages idle airflow without requiring a separate idle-control valve
- Provides individual bypass adjustment for balancing cylinder airflow
- Supports suitable ECU strategies including torque control, launch functions and automatic rev matching
- Removes mechanical cables and cross-bank linkages that can develop friction, flex or free play
Technical Details
- Six pre-assembled individual throttle bodies with two electronic motors and integrated position sensing
- Independent motors and dual-channel throttle-position sensing for the left and right cylinder banks
- Two fuel rails designed for short EV14 fuel injectors
- Six intake adapters and two throttle-driver connector kits supplied according to the selected configuration
- High-stiffness throttle couplings, sealed roller bearings and thermal-barrier cylinder-head spacers
- Vacuum connections for balancing instruments, brake servos and other vacuum-operated equipment
Installation and ECU Requirements
Installation, synchronisation and calibration should be handled by a specialist experienced with individual throttles and dual-motor DBW systems. The ECU must control two independent throttle motors and provide six analogue sensor inputs plus two complete four-pin half-bridge motor-driver outputs. Appropriate DBW fail-safe operation and engine limp modes are required. Adapt Motorsport identifies the MoTeC M150, Emtron KV8 and ECUmaster Pro 8 as suitable examples, although compatibility must be checked for each installation. Dual wideband oxygen sensors are recommended for closed-loop calibration of both cylinder banks, particularly at idle.
Configuration Notes
- Three-bolt versions can accommodate air conditioning
- A 993 retaining power steering and air conditioning requires short injectors and a low-profile fuel fitting
- This electronic ITB system is specified by Adapt Motorsport for off-road and racing applications only

- Porsche 970.1 Panamera S Hybrid V6 3.0L 2011-13
Diagram Ref No 9
Working in conjunction with the engine control module (ECU), accelerator pedal position sensor and throttle body, the throttle valve control unit continuously adjusts the throttle opening based on driver input and engine operating parameters. This precise electronic control helps optimise engine power delivery, fuel efficiency, emissions and overall drivability.
What This Product Does:
- Controls the operation of the electronic throttle valve.
- Regulates airflow entering the engine.
- Communicates with the engine management system.
- Provides accurate throttle response to driver input.
- Supports efficient fuel combustion and engine performance.
- Helps optimise fuel economy and emissions.
- Maintains stable idle speed.
- Contributes to smooth acceleration and overall drivability.
Symptoms Of Wear Or Failure:
- Delayed or unresponsive throttle response.
- Engine warning light illumination.
- Reduced engine power or limp-home mode.
- Rough or unstable idle.
- Hesitation during acceleration.
- Irregular engine performance.
- Throttle-related fault codes stored in the ECU.
- Unexpected fluctuations in engine speed.
- Difficulty maintaining consistent acceleration.
- Increased fuel consumption.
Why Replacement Matters:
- The throttle valve control unit is a critical part of the electronic engine management system, continuously processing signals and controlling throttle operation throughout every drive. Over time, electronic components can deteriorate due to heat, vibration, moisture or age, leading to unreliable throttle control and reduced engine performance.
- A malfunctioning control unit can cause poor throttle response, inconsistent acceleration and activation of the vehicle's fail-safe operating mode, significantly affecting drivability. Continued operation with a faulty throttle control system may also reduce fuel efficiency, increase emissions and place additional stress on related engine management components.
- Replacing a faulty throttle valve control unit restores precise throttle operation, reliable engine performance and smooth power delivery. A genuine Porsche replacement ensures factory-correct compatibility, dependable electronic performance and long-term reliability, helping maintain the performance, efficiency and driving experience expected from your Porsche.
