Has anyone got one of these ??
 

Road Dyno - Low cost engine tuning & diagnostic tool

Its a handheld dyno tester which has a internal memory which allowsyou to print off your cars performance - you need a 1/4 of a mile to test it on .


I've never seen them before but if anyone has one i would love to know if they are any good - it would be great for testing out my pulleys etc,

a guy sold one on here middle of last year, looked interesting, he said it was accurate.

I borrowed one and couldn't get it to work - partly because of the coilpacks (it needs an HT circuit fo RPM I believe) and partly because I think my suspension is too hard for it to generate a smooth curve. It's a great idea though, and in all fairness I really didn't give it enough of a fair test. My brother uses it regularly with consistent results.....

cool ,

just emailed the guy to get a bit more info
