Designed for a single RPM related function, such as rev control or shift lite activator. Works with the Stinger electronic ignition and GB 622 distributor. When used as rev control it allows the engine to run with 100% power to the set point and then interrupts (shuts off) the power to the ignition. When the engine drops below the set RPM it is restored to full power. This function is NOT to be used for shift points. It is to protect the engine in the event of a missed shift or trans failure. When used for a shift light, it lights the light at the set point to notify you that it is time to shift. Note: Both Stinger and Bosch 009 are wired by the standard ignition diagram. Warning: Do not have an engine failure due to a poor quality tachometer. Just because it may have a famous brand name does not assure you that it is accurate or fast enough for the VW like these are. Remember, if others were as good I would be selling them. |
