| I bought a Mychron 4 which is a small self-contained system that is maily used with karts, but will work on anything.
It's an LCD display with adjustable everything. It includes a lap timer but you need to add the trigger, either optical or magnetic pickup. You can add extra sensors like temperature, speed, gearing, etc. It just needs a wire wrapped around the HT lead to work on revs, and is very easy to setup.
Worth a look as I paid about £45 off ebay for it! |
