During the FIA Malaysian GP on the Speed channel, I saw a commerical for this Nology - PDA Dyno. It's suppose to connect to your ECU and give up (among other things) dyno data for your vehicle. How can this in anyway be accurate? Has anyone had any experience w/ this device? It makes a lot of claims that seem too good to be true.

I checked out the website and it looks like it's not avalible for the 350Z.

So this makes me think... is there anything equivalent to this device that is avaliable for the 350Z?
