From vapid 350s to killer major-blocks, Edelbrock can handle them all with its many EFI program offerings. When ACCEL replaced its venerable Gen VI DFI program with the new Gen VII, critics balked that its computer software was too cumbersome to navigate. Some of the additional well known aftermarket systems are ACCEL’s DFI technique, Electromotive’s TEC system, or a Motec program. From there, some programmers enable additional alteration of the fuel and ignition curves. An EFI technique consists of a fuel pump, fuel injectors, sensors and an Engine Control Unit (ECU).

Edelbrock’s new Pro-Tuner EFI technique, created in conjunction with MotoTron, boasts severe hardware for extreme competitors motors producing up to 1,500 hp. Kits are based on either a Victor or Super Victor single-plane manifold converted for EFI use and contain fuel rails and injectors. A clogged or improperly adjusted injector will produce an uneven distribution of fuel mixture amongst the cylinders. Things like air temperature, manifold pressure, throttle position, RPM are all collected and analyzed by the ECU in order to establish how significantly fuel to provide to the engine.

Carputing revolutionized late-model GM EFI tuning with the introduction of LT1-Edit in 1999, which permitted levels of tunability generally connected with aftermarket computers at a fraction of the price. Immediately after you enter bore and stroke dimensions, compression ratio, cam specs, fuel stress, injector size, and cylinder head specs, CalMap automatically generates a custom baseline program to get you up and running. The nucleus of every EFI program is the Powertrain Control Module (PCM), which interprets inputs from the sensors and relays guidelines to a variety of engine components. For alternative fuel applications fuel rail stress and temperature sensors are also utilized.

The EMS is comprised of sensors for intake air and coolant temperature, turbo boost and intake manifold absolute pressure (MAP), throttle position (TPS), engine rpm and position, and exhaust oxygen sensors (UEGO or HEGO). When just about every EFI setup is various, a fundamental upgrade entails replacing the carburetor with a throttle body and installing injectors in the intake manifold.

The patented Direct Fire ignition system capabilities a separate coil pack for every pair of companion cylinders, which according to Electromotive, gives additional power and 10 instances additional spark duration than competing capacitive-discharge systems. A couple of drawbacks to a mass flow technique consist of its cost and all round design, which can restrict airflow in high-horsepower engines.
