Mychron 3 660 drag racing data analizer. Will record head temp, exhaust gas temperature, jackshaft rpm engine rpm mph etc all the way down track. Retails for around $500, Probably not something you want on a fun kart...
It will give you lap times, RPMs, and a temperature of your choice (cylinder head, water, or exhaust gas). Plus, you can add eBox or GPS down the road.
Its Josh from AIM sports. I be believe he is the one who repaired our Mychron 3 660. I think ours is 2 years old? We have been having a problem with it recording runs. Payed to send it to Mychron came back doing the same thing it was when we sent it in.
This winter we will probably be shipping our Mychron out to you guys for repair. Worst thing is it cost us like $70 shipping and like 3 weeks downtime to you guys and back for it not to work the first time it was shipped.
