Made in USA. Sealed in epoxy, works well in harsh environments. Water resistant, temperature resistant, and looks neat. For more info, go to our website.

Three color, and the air/fuel ratio is indicated right on the face (6 LEDs).

Excellent for motorcycles, off-road and other harsh environments. Also a great choice if you plan to tune a carburetor with your AFM (see our dual-quad 'Cuda project car).

Chapter Features

Construction:
Constructed from carbon-fiber, epoxy, and housed in aluminum. Validated the design by alternating between 50ºF water, then in 212ºF water for 30 minutes.

Function
Usable during closed loop (off WOT). Buffer slows the speed of the signal reactions, so you can see the mix signal move rich to lean. 6 LEDS because we believe that's usable accuracy of the oxygen sensor.

Practical
2"x1"x3/8". Great start for cycle bar-mount. Using Velcro (we can supply) makes it simple to remove the AFM and install it in other vehicles.
