Ross, the AIM dash is like the Motec ADL but much cheaper. We had ADL's in our Hayabusa clubman's a few years back, but the Motec gear is soooo exy!
The AIM unit does heaps of logging and is a great unit. If you are looking to log g forces, steering angles etc, then the AIM dash would be a good call.
Whilst on geeky things:
At wakefield the other week, Dave was racing the Elise with a small laptop strapped in. He has set up a remote log-in, and had his mate in england logged into the ECU looking at live fuel, lambda, oil etc while he was racing!! Amazing that this technology is available to us neville nobody's these days. Not so many years ago it was formula one stuff.
