Electronic Ratio Adapter (ERA), For Recalibrating Electronic Speedometers

Correct Your Speedometer With the ERA

Changing your tire size or rear gear ratio will make your speedometer inaccurate. The Electronic Ratio Adapter (ERA) can take care of this problem for you. The ERA receives the current speedometer signal from the speed sensor and will output the correct speedometer signal to your speedometer. The ERA four step wiring is a snap. The ERA is compatible for most cars and trucks.
