123ignition Fully Mappable Distributor Triumph TR5 to TR6

Fully mappable 123ignition Distributor suitable for 6 cylinder engines as fitted to Triumph TR5, TR250, TR6, GT6, Vitesse, 2000, 2500 & 2.5Pi . 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).

The original Triumph mechanical Tachometer will need to be converted to electronic when fitting this distributor, see ELC201

For 6 cylinder engines we advise to change your coil to a high performance coil because of the short load time in the higher rpm range. Make sure you use coils with a primary resistance of at least 1.0 Ohm. ( 1,0 Ohm or more ) For standard street engines we advise a “Bosch Blue” or “Beru ZS106” coil. For high rpm engines a “Bosch red (0 221 119 030)” or “Beru ZS109” is much better.
