FP Performance Electronics- SEFI8LO Engine Management System

FP Performance Electronics^tm introduces the SEFI8LO Engine Management System. This state-of-the-art system allows the engine tuner to take precise control of an EFI engine's operating parameters. The base SEFI8LO unit is a bank-to-bank fuel injection system that's fully upgradeable. A sequential fuel injection upgrade is available that allows the sequential firing of each injector once per combustion cycle. Another SEFI8LO option allows the system to run "closed loop" with feedback from a wide-band oxygen sensor. For the ultimate in engine power and efficiency, an optional upgrade kit for sequential units delivers individual cylinder timing and fuel control.

The SEFI8LO ECU (Engine Control Unit) has a waterproof case and circuitry that's hardened to prevent EMI (Electromagnetic Interference). In bank-to-bank mode the unit has the capability to drive up to 8 high or low impedance injectors (4/1 amp driver per injector). The bank-to-bank unit fires, at most, two injectors per side and delivers more stable fuel preasure than batch fire systems. In "closed loop" operation the system runs with a wide band oxygen sensor, allowing the system to adjust injector pulse width to match user programmed air/fuel ratios. Each SEFI8LO system includes PC compatible CalCom^tm an easy to use, icon driven software program. The software offers 32 bit compatibility for a complete memory map of system calibrations.

SEFI8LO™ is a new engine management system from FP Performance, a Fel-Pro® company, that elevates automotive and morine performance to a new level by taking precise control of an engine's operating parameters.

The SEFI8LO is a true Speed-Density system that is offered as a base unit with several upgrade options and is engineered for maximun performance in a variety of engine management applications.

Included in the system is CalCom™, an easy-to-use software program that runs on virtually any PC and allows the precise calibration of all engine management functions.

Standard Features

Base Unit will drive up to 8 high or low impedance injectors in bank-to-bank fuel injection mode. This mode fires at most, 2 injectors per side at any one time and will reduce fuel pressure fluctuations over batch fire mode resulting in better fuel distribution to all cylinders. Each injector is controlled by its own peak/hold driver.

Base Unit has 16 x 17 spark and fuel matrices for ultra-control of the engine spark and fuel events.

Base unit is fully upgradable. Systems can be later updated for sequential fuel injection, closed loop - wide band O2 sensor fuel conttrol and individual cylinder fuel and spark trim.

Waterproof enclosure allows for under-hood mounting.

EMI Hardened Design. This system was designed to be immune to the eloctromagnetic interference common to hi-energy ignition systems.

True Speed-Density algorithm greatly reduces calibration time and improves idle characteristics with big injectors.

Compatible with all crank triggers and ignition systems.

2 stage wet or dry flow nitrous control

Hi-speed communication from the ECU to host PC
