The 123 Ignition System is a complete replacement distributor, incorporating a sophisticated solid-state microprocessor housed within a polished aluminium body.
This user programmable, dual polarity 123 distributor allows users to map their own ignition curves; making them ideally suited to MG owners looking to switch between road and track settings with the minimum of fuss! (Laptop required, minimum system requirements apply. Contact our sales team for more information).
Delivery of the timing through a microprocessor provides superior accuracy, reliability and responsiveness over standard ignition systems.
If you want to tune your engine or have an engine for which there is no standard distributor available, by connecting it to a Windows computer, you can easily adapt the 123 TUNE to fulfil 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.
A proven and simple to install performance ignition system, 123s are now fitted to thousands of MGs.
Available for all classic MG models from MGA onwards, offered for positive or negative earth, with or without vacuum advance, Side or Top Entry cap. T/E (top entry), S/E (Side entry).
