That looks like nice stuff. Not cheap. Have you thought about the Racelogic Performance Box?
Do you do alot of track days?
Haven't done any lately as I'm waiting to get my car back (this week
) from VW Racing after a strip out.
The Race Technology DL1 logger & Dash3 is probably a bit OTT for the odd track day, the Performance box would give all the info you'll need really, but you can have input sensors, Trackmaps with satellite overlay and software that shows all sorts of stuff, you could bore your mates stupid
Not quite the same, but have you seen this? Harry's Laptimer. Loads of data aquisition and some other neat features too.
I've heard about these 'mobile telephones' I'm really not sure they're going to catch on
