1. Was a successful calibration completed as per the installation manual (no blinking lights at the end)? This is critical, and without it, Auto-Blip will not work as designed. It may be necessary to repeat the process more than once to achieve the desired result. Please review the calibration instructions, special attention to the section right below step 10. AB is self diagnostic, any blinking light(s) after calibration  is completed need to be addressed.

2. Tapping into the wrong vehicle wire will definitely result in a failed installation.  Vehicle manufacturers aren’t always consistent about wiring colors, so it helps to be able to recognize/test the various wires in order to determine you are tapping the correct one. When available, prioritize wire position on the diagram, before wire color. Access to your vehicle wiring diagram may be helpful in some cases.

3. When identifying the wires to be tapped, prioritize the written instructions vs. pictures, as manufactures may change a wire color but not likely a wire position. In some vehicles, identifying the clutch safety interlock switch could be a challenge. This is so because some vehicles have 2 switches at the clutch. You want the one at the bottom of the pedal travel (see manual for more details).

4. Incorrectly tapping a vehicle wire is the most common installation fail. The connectors we provide (Posi-taps) are best in industry, but can be finicky to install. Instructions for the proper use of Posi-taps can be found above on the file: Posi-tap connectors user guide. Please read these instructions carefully as they may help you identify a possible installation error. It is very important that the pin inside the Posi-taps connector goes through the center of the wire you are tapping into. The smaller the wire gage you are tapping, the higher the chance of a fail.

5. ECU error codes/faults – Once present, must be erased prior to performing the required calibration.

APPS SIGNALS

The accelerator pedal position sensor (APPS) indicates the position of the accelerator pedal. On sensors that use 2 potentiometers (some use 3), when the accelerator pedal is pressed, the signal voltage value of one potentiometer increases while the other decreases. These values, which typically range from 0.5 V to 4.0 V, are fed to the ECU, and if there is a discrepancy, the throttle goes into ‘limp’ mode (poor/noisy ground can cause this). Signal values may vary with different engines and APPS. AB is designed to work with 0-5 volt throttle position sensors.

BRAKE / CLUTCH SWITCH

Auto-Blip requires signals from both the brake and the clutch (in that order) to release the ‘blip’ signal. The desired signal value:

• Brake signal  +/- 12v to 0 Attention! You want the wire that carries the signal to turn the break light on when the break pedal is engaged
• Clutch signal  +/- 12v to 0  Attention! Most clutch pedals have two switches. You want the Safety interlock switch located at the end of the clutch pedal travel, specifically the wire that carries the signal  that tells the ECU that the clutch is engaged to allow the engine to start
