The Powerjection III is an amazing accomplishment in engineering. It is by far the simplest and cleanest aftermarket EFI system available. Which also means it is the easiest to install and tune. The "Adaptive Learning" feature eliminates the necessity for laptop programming and tuning, except on the most radical engines. By "cleanest," we mean it has minimal wiring showing, so for those street rod, street machine, and custom car enthusiasts who object to other EFI systems because of all the engine clutter with wires running everywhere, this is the system they have been waiting for. And just because this is the simplest...as well as one of the least expensive aftermarket EFI systems...don't consider it a cut-rate design with important features left out. First it utilizes a wideband O2 sensor, a feature missing from many competitive units. It also has a 2.5 BAR MAP sensor which means you can run up to 25 PSI of boost if you have a supercharger or turbocharger. The fuel pump comes with a combination heat sink and mounting bracket. The EMS (engine management system) mounts directly on the throttle body eliminating a major portion of the wiring required. This means you do not have to cut a hole in the firewall. 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 mounted sensor to the manifold. Professional Products pioneered the "Adaptive Learning" feature which has been marketed now for over two years and our competitors are just now attempting to catch up. The "Adaptive Learning" feature basically does your tuning for you. At initial setup you enter a few basic simple inputs into the system with a laptop and the computer creates your own custom MAP for your vehicle. Then you take the car out for a short spin with some normal driving coupled to a few full throttle bursts and the EMS literally rewrites the program specifically for your car. As you continue to drive the car, the EMS is constantly adjusting the air/fuel ratio to match the conditions such as temperature, altitude, and any other driving situation you might encounter. This is by far the most technologically advanced EFI system available.
Key Features:• Most compact full featured aftermarket EFI available. • EMS (computer) mounts directly on the throttle body eliminating most of the wiring found on other systems. • No need to find a mounting spot for the computer. No hole through firewall for harness. • Utilizes wideband O2 sensor which provides far better performance and tuning than found with narrow band sensor used on many competitive EFI systems. • Idle Air Control, Fuel Pressure Sensor (when utilized), throttle position sensor and MAP sensor all contained in throttle body assembly which eliminates mounting hassles and additional wiring.
Complete Returnless Style Kit Includes:• 750 CFM Throttle Body Assembly (Dimensionally an exact swap for a 4150 Holley with identical linkage) • Throttle Body and Air Cleaner Gaskets • (4) 62 lb./hr. port style injectors • Built in EMS (Engine Management System) Incorporated on the throttle body • Dashboard Software CD with comprehensive Instruction Manual • All harnesses and connectors (Much less harnessing than competitive systems which means less installation time and hassle) • Idle Air Control - Built in to the throttle body • 2.5 BAR MAP Sensor - Built in to the throttle body • Coolant Temperature Sensor - 3/8-NPT threads for most manifolds • Throttle Position Sensor • Wideband O2 Sensor and cable (Many competitive units only have narrowband sensors which do not provide adequate tuning parameters) • O2 Sensor Bung and Clamps - No welding necessary for mounting • 10409 Fuel Inlet Kit • 70151 EFI 220 L/H Fuel Pump • 70160 EFI Fuel Filter • 11113 EFI Fuel Pressure Gauge - 0-100 PSI • 70035 FuelOnDemand Module • 71235 Fuel Pressure Sensor
