ARM1 Air/Fuel Ratio Monitor Kit

The ARM1 is a miniature air/fuel ratio meter that features an ultra-bright, easy to read, five-color display. It may be used with the stock oxygen sensor or a dedicated sensor such as RPW-9900 (see right). High precision circuitry is used to provide accurate readings and ensure that the ARM1 doesn't interfere with the operation of the oxygen sensor. The ARM1 has automatic night dimming to reduce the display brightness at night. It's available for both OBDII and non-OBDII applications.
