Electronic Individual Throttle Body Kit. Porsche 964 / 993  ❭  AMS9050292-

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.

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
