Overview

Summit Racing™ MAX-efi 500 Fuel Injection Systems

Summit Racing™ introduces its MAX-efi 500 Fuel Injector System, the most efficient way to convert your carbureted engine to premier EFI performance. These self-tuning throttle body units bolt directly to most 4-barrel manifolds; then, through their wideband oxygen sensor, the systems continually adjust fuel delivery to provide the optimum air/fuel ratio under all climate and altitude conditions. MAX-efi will support up to 500 hp, and the self-learning ECU allows for easy tuning.

With safety in mind, these systems are also designed with a self-adjusting "limp home" mode to protect your engine if a sensor fails. In addition, they include a data-logging feature to track the system while it's running to ensure optimal performance.

Other features of the Summit Racing™ MAX-efi 500 Fuel Injector Systems:

* Powered by the most advanced self-learning technology available
* 4-injector system is capable of supporting stock to 500 hp engines
* High-flow aluminum throttle body with four 45mm diameter throttle bores
* OE-quality wideband 02 sensor and TPS sensor included
* Color touch screen hand-held controller
* Billet aluminum anodized fuel rails
* Compact external ECU for easy mounting
* OE-style harness is clearly marked for easy installation and durability in extreme conditions
* All sensors except the wideband 02 sensor and coolant temp sensor are integrated on the unit
* Uses commonly available sensors for easy replacement if necessary
* System uses a Temperature Manifold Absolute Pressure (TMAP) sensor instead of a MAP sensor, reading both air pressure and temperature
* Fits square bore or spread bore intake manifolds. (Spread bore manifold requires an inexpensive plate to avoid leaks. See SUM-G1420)
* Works with original carb-type distributor, factory-style throttle linkage, and most 4-barrel intake manifolds
