What we do

TechnoVersions LLC designs and builds products for the automotive industry. These include products for testing, as well as converting gauge signals to make things work. With rare exception, all products are kept in stock and ship within one working day from receipt of order. All of the products are designed and manufactured in the USA.

We will be closed beginning on Monday May 11, and ending Tuesday May 26 (Memorial Day). Orders received during that time-frame will ship out on Wednesday May 27.

Analog Gauge Converter: MeterMatchTM

MeterMatch is used to allow analog gauges (such as fuel, temperature and oil-pressure) to use senders that were not originally designed for that gauge, and provides for an alarm indicator if normal readings are exceeded.

Tachometer Converter: TachMatchTM

TachMatch is used to convert ignition RPM signals from the engine to the tachometer. It is used if the two are electrically incompatible, or if the tachometer expects a different number of cylinders than the engine, such as after an engine or tachometer swap.

Z-Car Diff Mount

The Diff Mount is an extra strong front differential mount for Z-cars that have more power than that supplied by the factory.

Tach Tester

Tachometer Tester

The TechnoVersions Model TT-01 Tachometer Tester is designed to test almost all types of automotive tachometers, either on the bench or in the vehicle.

Thanks again for solving a year’s long problem for me.

You helped me solve our 280z tach issues and I've used your TachMatches in every car that needed it since then. We really love your product!

Very satisfied with the end result. This thing is great and you have been excellent on providing customer service for a local product that is every bit as good as anything you can buy from the big-name brands.

Got it working. Thanks so much for the help. The up down buttons were just a bit non-linear and it didn’t look like it was working but it was. Works perfect.

I got the box on Saturday, that was an insanely fast turnaround time. THANK YOU!!! I just finished the install and I didn’t realize just how clunky the rear was until the test drive!!! One of the best mods for sure!

I sent you an older tach a couple of years ago and it still works great. I hope you can do the same for these two tachs.

I unsoldered the original electronics in my Sun EB-9A transmitter and placed my TachMatch inside. Installed in my car, the original transmitter looks original and, thanks to your electronics, actually does drive my restored Sun RC tachometer. Thanks for a great product.
