Sounds pretty cool.

Now as long as everyone is using the same tool to measure their performance, then the data will be consistent. I can see some people questioning the accuracy of the HP / TQ numbers, compared to those recorded from a standard dyno. It's all perception though.

How accurate do they say the dyno numbers are compared to a real dyno?

I'm thinking the 1/4 mile will probably have faster recorded times then actual strip timers, since the driver reaction time is not factored into the ET.

Sounds great for tuning needs though.

wow it kind of requires that you know a bit about your car though. i.e. im not exactly informed on what the drag coefficient of my car is. sounds great for a real gadget junky though kind of want something like this.
