This kit utilizes a Haltech Elite 750 standalone ECU to control fuel and spark, replacing the factory Motronic system on the 3.2L Carrera Porsche 911s. It uses the factory 3.2L intake manifold and throttle body and fuel injector style, but adds a Clewett Engineering distributorless crank trigger ignition with coil-on-plug (COP) ignition coils.
Kits can be configured with various fuel injector sizes, upgraded to Haltech Nexus S3 ECUs, and crank & cam trigger kits. A hall effect throttle position sensor (TPS) for the factory throttle body provides a high resolution and reliable signal to the ECU.
They can include pulleys with or without provision for A/C compressors, or upgrade to a serpentine belt conversion.
We can also configure the kit with Bosch 3x2 style ignition coils and spark plug wires instead of coil-on-plug if desired. See: EFI Conversion with coil pack

Options and upgrades:
- Installing a Cylinder Head Temperature (CHT) sensor is recommended for better monitoring and compensation of ignition timing and fueling as the engine temperatures change. Kit 9191-98.
- Dual wideband sensor kit to allow an O2 sensor per cylinder bank is recommended for best performance and ease of tuning
- A more advanced Nexus S3 ECU and wiring harness upgrade allows for knock detection/control and advanced engine protection features
- Twin plug engines can add bottom coils (CNP kit 9107-99)
- Idle Air Control Valve kits are available (1001-76-STR)
Wiring:
This kit configured with the flying lead wiring harness will require professional installation with a familiarity with automotive electronics and creating wiring harnesses.
We can offer completed wiring harnesses made for your application and kit. Please contact us for pricing and lead time on completed wiring harness options.
Calibration (Tuning):
We can provide a basic starting file to load to the ECU that has inputs and outputs configured for the included wiring harness and kit components. This is just a starting point, and does not replace calibration/tuning as settings and ignition/fuel maps are different for every engine/car.
The calibration of the ECU settings (tuning) will require a professional. Our recommendation is to work with someone nearby who can dyno tune the car. Remote tuning options are available, but then troubleshooting the wiring and installation is up to the installer. Feel free to contact us for recommendations on installers and tuners.
