Edelbrock 35070 - Edelbrock Pro-Flo 2 EFI Systems Details
Small Block Chevy
These Pro-Flo 2 systems are designed for 1986 and earlier small-block Chevy engines with standard or Vortec-style heads like the Edelbrock E-Tec aluminum heads, and unique 4V air valve for even greater performance potential.
The Edelbrock Pro-Flo² EFI System is the second generation version of Pro-Flo electronic fuel injection systems. This system has been upgraded with new powerful electronics featuring full-sequential injection and all the components you need to convert a carbureted engine to EFI.
For non-emissions applications, each system includes:
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-Flo² 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-Flo², 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-Flo² software on a laptop or PC.
If laptop tuning is preferred, use Pro-Flo² software to tune, save, and restore unlimited custom calibrations. Use ''I-link'' to connect online to Edelbrock Tech Support.
