There is no denying that fuel injection is an efficient and reliable way to run your engine. Using an electronic control unit (ECU), fuel injection can provide stable drivability without the constant tuning often needed with a carburetor. Professional Products has brought electronic fuel injection to a new level with their new Powerjection III.

The Powerjection III is an affordable and compact EFI system that offers easy installation and stealth looks. Powerjection III packages the ECU directly onto the throttle body, thereby eliminating nearly 80% of the necessary wiring harness of comparable systems. For street rod, muscle car, and custom car enthusiasts who are put off by EFI systems because of wiring cluttering up an engine compartment, or simply want the look of a carb with the drivability of EFI, this is the system you have been waiting for.

Powerjection III’s “adaptive learning” feature eliminates the necessity for laptop programming and tuning, except on the most radical engines. Simply install the EFI, fire it up, and drive it around for 30 minutes or so while the system dials itself in. It continues to fine-tune itself as it adjusts to your driving habits and various atmospheric conditions.

Powerjection III utilizes a wideband O2 sensor for the most precise engine tuning. It also has a 2.5 BAR MAP sensor, which means you can run up to 20 PSI of boost if you have a supercharger or turbocharger. Additionally the MAP Sensor is packaged into the throttle body, which means one less component cluttering up your firewall and no vacuum hose needed to run from the firewall to the manifold.
