i remember meeting a guy that had this thing in his car which stuck to the windshield, and clocked his 0-60, quarter mile times etc. i tried looking for it online, but cant find it, what are those things called, if so which brands are best, ???

And not many people like them, but I can't recommend either way as I have never used one.

They're not always 100%

If you buy one, get one used on ebay. That way a month later you can sell it for the same amount. I hear they are neat, but you get bored with it quick

Yeah, not worth the $$$.

i'll sell you mine, i only used it once. paid $200.00 for it, i still got reciepts and handbook.

Hardest thing about using one is having to make sure it was level and having to reach the windshield to push the button. Like tdogg31, used once and sold to a co-worker. If you have a Palm Pilot, you can get a pda-dyno & obd scan tool from NOLOGY. Plugs into the Palm and haves alot of tools and functions w/ a multi-gauge function. Takes a little getting used to but works well.

lol./...i bought one on ebay....for 15 bucks....it came with in .2 seconds on my SATURN (that ended up being totaled) and it cam with in .1 on the mustang......the only thing is, you have to have them set PERFECTLY...or the reading is off
