Speaking of smartphone apps ( I love the Tracks walking/running app for android, btw), has anyone tried the smartphone-based data-logging, quarter-mile and dyno apps?

There was a write up on one of them in one of the tuner mags floating around out there (my friend had one lying around) that determined that it was a fairly plausible concept if done correctly and could yield numbers for HP and Torque within the same 10% margin-of-error range as a real dyno.

One of the paid-for Iphone apps even had functions for datalogging through an OBDIII port on your vehicle. You would, of course, need to buy/supply a cable.
