Knowing your engine's air/fuel ratio is critical to maximizing its performance. Knowing the RPM that air/fuel ratio is occurring gives you the data needed to make precise adjustments to address specific tuning problems. The FAST Air/Fuel Meter RPM Module is an upgrade kit that lets you monitor and record your engine's RPM and is fully compatible with any FAST Air/Fuel Meter. It installs with a quick firmware update to your meter, and the RPM module plugs in-line with your existing O2 sensor harness. The RPM pickup is a unique inductive design that eliminates any wire cutting to get your RPM signal.
The FAST Air/Fuel Meter RPM Module comes with everything you need, including the installation CD, communications cable, USB cable adapter, power source, RPM module, clip-on inductive pickup, and instructions. Best of all, you'll never have to guess what your air/fuel ratio is or what RPM it occurs at ever again.Features:
