    I love these units. You can put a tachometer on literally anything. Canโ€™t go wrong with them. Our aircraft the Hummel UltraCruisers are equipped with a high performance and highly modified engines similar to the Harbor Freight Preditor 670 v-twin called a Clarus. Between 45-50hp and around 100ft lbs at the prop. They come with a wire wrap inductive tach pickup. Set switch 7 and connect according to the instructions. Simple. Works flawlessly at 7 wraps. And accurate as well. 5-stars.

    Fantastic little device - Very versatile and adaptable

    I've been using a Racepak data logger for years with my Formula Vee race car which has a distributor and external ignition coil. The tach signal has been problematic using a GMR sensor which had to be placed at a precise distance from the coil to work and with vibration and movement would invariably lose a signal at the most inconvenient time. This Tach adapter changed all that allowing me to get a signal directly from the noisy negative post of the coil and convert it into a signal that the data logger can read directly. I was supplied a 230K resistor to use on the input signal to help filter the signal and it works beautifully. The unit is tiny (matchbox or smaller) and easy to connect. The dip switches allow the signal to be filtered further if needed and the ratio of pulses can be ...

    Easy to fit converter

    The tach converter comes with good clear instructions and is easy to fit. It is a shame that it doesn't come with a few extra resistors (which only cost a few pence) as in my case they were required to get the rev counter to read smoothly. The hefty charges made by electrical suppliers to send out a very cheap part outweighs the component price 10 times over. Also consider the import charges when buying from America as this is half as much again over the purchase price. My 4 cylinder tachometer is now reading an 8 cylinder engine. At lower engine speeds it seems quite accurate but at higher rpm the tachometer does become more of an aesthetic feature than an accurate instrument. Nevertheless it retains the originality of the dashboard rather than needing an aftermarket gauge bolted on. I ...

    Surprise noncompatable fine print

    Not what I thought I was getting, after reading all instructions 3 times it makes a general statement that this UTA will not work on ''newer'' tachs. Just a general statement, nothing that tells me how to determine the compatibility short of trying. Guessing that trying this unit and if it doesn't work I'll have a part that will sit on my work bench and collect dust. I've checked the listing for more information and still feel more product info is necessary. Would not recommend because ''What is a NEWER tachometer'' as described in instruction.

    Great little box! big time saver.

    I was trying to retrofit a modern arduino based tach to an 20yr old motorcycle and the waveform is all wrong for that. This little box fixed me right up! If you need a good output signal from a spiked pulse on a coil. This will work for you. It was a lot smaller than I expected which was great. I would also love a non-mounted version that I could solder into a loom or somewhere completely out of the way but this will work for just about anyone.

    Tach adapter

    Used this on a 1983 Toyota Supra along with the tach amplifier, also supplied by this Ebay seller, after installing an LS3 6.2L chevy engine in. Works amazing!
