The second generation of Pro-Flo has full-sequential fuel injection and new powerful electronics with all you need to convert a carbureted engine to FI.
For non-emissions applications, each system includes:
Intake manifold with fuel injectors, fuel rails, and throttle body
Wiring harness
Engine control unit (ECU)
Narrowband O2 sensor
Handheld calibration module
Installation hardware
Pro-FloČ software
Flash-Programmable ECU
Engineered by EFI Technology, a world leader in advanced electronic engine management, this control unit features flash-programmable memory and full-sequential injection (individual injector firing). Flash memory allows multiple tuning options, including Map-N (Speed Density) and Alpha-N (Speed Throttle). Map-N references RPM (engine speed) against MAP (manifold absolute pressure) to determine fuel and spark requirements; Alpha-N references RPM against throttle position. A base calibration is preloaded, and base calibrations for common performance engines are on the included CD. Use Pro-FloČ software to create custom calibrations. Closed loop fuel targets with included narrowband or optional wideband O2 controller are also supported.
Handheld Calibration Module
Edelbrock pioneered tuning on-the-fly FI with the original Pro-Flo that featured an exclusive handheld calibration module. Also included with Pro-FloČ, this unique module plugs into the ECU for fast access anytime. Save up to three calibrations. An easy-to-read display allows real-time adjustments without a computer. Initial calibration, however, must be loaded with Pro-FloČ software on a laptop or PC.
Pro-FloČ Software
If laptop tuning is preferred, use Pro-FloČ software to tune, save, and restore unlimited custom calibrations. Use "I-link" to connect online to Edelbrock Tech Support.
