doesnt sound like it would work to good.

 

Sounds fishy. I wonder if youre at a standstill, if the tach function would work. I dont know of anyway, rpms can be deduced from voltage or amps, post voltage regulator( such as a cigg lighter). Its posible to get rpms from the a/c side of the alternator, but not the d/c side of the system.

 

i was wondering the same thing. all i know is that in a car the 1/4 mile is =/- .2 ths of a sec. my friend has one and when he ran at the track it was on average like .2 off. the hp and torqe was kinda good tho cause i tryed it in my truck and it was within 3 hp and 7torque of the stock specs. wire a cig lighter onto your bike and try it out.
