123TUNE-4-A-V-FIAT-TC


The USB programmable 123\TUNE-4-A-V-FIAT-TC is designed to replace the mechanical distributor (mounted on top of the cylinder-head) in the popular Fiat twin-cam engines.
If you want to tune your engine, or you have an engine for which there is no standard distributor available….. And you are a Windows PC user, the 123\TUNE is the answer! By connecting it to a computer, you can easily adapt the 123\TUNE to fulfill even the most demanding requirements. The unit offers two sets of curves that can be selected by placing 12 Volt on a wire from the 123\TUNE. Handy, if you’re driving on two different fuels, like regular fuel with LPG or with Ethanol

123ignition has been active in the field of classic cars for more than 15 years and through this became a respected brand. The company started in 1992 and from 2001 fully focused on electronic ignition systems. The first prototype ignition was born out of passion a couple of years before. A project was started to provide an electronic ignition for a Citroen 2CV. This turned out to be such a great success that the project was turned into a product. Meanwhile, the assortment expanded more and more, and we can now offer a suitable product for many classic cars.
