123 Ignition Fully Mappable Distributor – TR2-TR4A

Fully mappable 123Ignition distributor suitable for TR2-4A & Morgan +4 engines. Adjustments can be made by connecting the distributor to a computer running the 123 software, this allows the end-user to easily tune to match their requirements. The unit offers two sets of curves that can be selected by placing 12 Volt on a wire from the 123TUNE. (Handy, if you're driving on two different fuels, like regular fuel with LPG or with Ethanol). Two centrifugal advance curves (500 to 8000 rpm), two vacuum-advance and boost-retard curves (0 to 200 kPa or -30 inHg to +15 psi), two MAP-start fields, two rev. limiters (advanced random spark stealing).

The software includes; real-time tuning under keyboard-control (ideal for working on a rolling road), rpm-stopwatch (ideal for tuning using the road itself as a rolling road), luxurious import-from-file and export-to-file (curves can easily be exchanged over the internet), electronic "dashboard" with temperature gauge (selectable in degrees Celsius or Fahrenheit), manifold pressure (selectable in Bar or inches Hg / Psi), rev. counter (0 to 8000 rpm crankshaft), spark-energy gauge (primary coil current) & total-advance gauge (in degrees crankshaft).
