Tachometer High RPM Recall Kit, Intellitronix, 4/6/8-Cylinder

Now you can have high RPM memory recall on your factory or aftermarket tachometer. Designed to work with any electric tachometer and also on your factory electronic tachometer. Simply connect the little black box in between your existing tachometer and the tachometer signal from your ignition. The microprocessor monitors each incoming tachometer signal and saves the highest reading. In normal mode, the microprocessor simply sends the incoming tachometer signal straight to your tachometer, but when you press the button, the microprocessor recalls and sends the highest signal to your tachometer instead of the one coming from the ignition. This product includes a lifetime warranty, and this product is made in the USA!
