you can get the gtech from tesla the basic one runs/4 g's and 0-60nd 60-0 for around $140
the new version does all that with better accuracy torque and hp, inteligent shift light and some other cool stuff i cant remember
check them out here http://www.nipponpower.com/electronic/meter/gtech.html
how on earth can thise device work ? just hooked though the cig lighter ? i can possibly understand how it might be able to determine rev's by perhaps some interference in the power signal form the alternator going around but other than that how on earth can it work out power outputs.
