Edelbrock 3532 - Edelbrock Air/Fuel Ratio Monitor Details

Air/Fuel Ratio Monitor

This Edelbrock Wide Band Air/Fuel Ratio interface unit will not only work with all current Edelbrock EFI systems, but with any aftermarket EFI system that can accept a 0-5 volt input for monitoring Air Fuel Ratios. Features two independent 0-5V analog outputs that are linearly scaled with 0V=10.0 AFR and 5V=20.0 AFR. Includes interface unit, sensor, weld-in bungs and all necessary wiring. Does not have internal data logging capability and only includes a single oxygen sensor. For data acquisition applications requiring two oxygen sensors, use Dual Channel Wide Band kit #91170.

Allows improved Closed Loop control of the current Pro-Flo EFI systems

Suitable for automotive, motorcycle, and other 4-Stroke engine applications

Highly accurate with less than +/- 0.10 AFR error over 10.3 - 19.5 AFR range

Easy free-air calibration procedure corrects for sensor aging effects

0-5V analog AFR output for interface to EFI, Data or Dyno instrumentation.

Wide supply voltage range from 11-18V allows operation from battery on small engines or race vehicles with out an alternator

Current draw is approx. 1 amp

Features compact 4" x 2" x 0.5" water-proof enclosure

This air/fuel monitor consists of an O2 sensor and a calibrated electronic display. Simply install the O2 sensor in the exhaust pipe, and then connect the display. When the engine is running, the actual air/fuel ratio is continuously displayed. The monitor indicates air/fuel ratios from approximately 12 to 15. Use it to guide carburetor adjustment and jetting or to improve ignition spark advance curves. Not recommended for use with leaded fuels.
