What the bloody hell is this, and how does it do what it does?! I was thinking GPS but that doesn't make sense for horsepower and RPM...

Very confused <---

Uses an accelerometer plus some basic facts about your car (mass etc...) to calculate power, then torque.

Simple maths for those that know.

Nowhere near as cool as I was hoping then! Damn glorified calculators

Have you considered the Veypor VR2?

It has a similar range of functions.

I hadn't really thought about it yet, haven't even been out in my indy yet (still tidying bits up), and saw what I posted for sale on another forum.

The VR2 certainly looks nicer
