Wide Band Air/Fuel Ratio Meter (Out of Stock / Discontinued Product)
No matter if you have a stand alone engine management system or a piggy back fuel control, the Wide Band Air Fuel Ratio Meter is a must for a serious tuner! The slightest adjustment of the Air/Fuel mixture is being shown on the Wide Band display. Finally you can tune for more power, closer to the edge, precisely monitoring Air/Fuel ratio through the entire RPM and throttle position ranges.
The Wide Band Controller and Display is so small, it fits on a palm of your hand. It's a size of a deck of cards!
Quick summary of the Wide Band Air Fuel Ratio Meter::
The display contains 20 multi color LEDs and back lighted AFR ratio numbers. There is 15 LEDs for the rich side (performance tuning) and 5 for the lean side. Stoich 14.7:1 air/fuel ratiois back lighted by a cool blue LED which you see at the closed loop ECU operation (most of the time). Also, for a quick identification, there are different colors dedicated to different AFR ranges. These are extra bright LEDs very well visible in a daylight.
During many tuning sessions we found out that fast changing numbers are relatively hard to read comparing to the high resolution bar display. This is not typical .90 to .94 narrow band O2 read out and the AFR numbers are changing very rapidly. Fast response time of the bar display allows you to notice even the shortest rich on lean mixture spikes practically invisible on a numeric display.
