Scott, I started reading that info from that web site and was saying, "shoot, is it time to buy a 3rd scanner!"

.
DON'T BUY IT! Although the feaures look great and the interface looks nice to use, it is dependant on the ELM hardware interface. I bought the Digimoto scanner which also uses the ELM hardware interface and it's terribly slow talking to the computer. It's SO BAD that it makes any real-time usage like tuning completely imposible! I thought it was just a problem with the unit I had until I started doing some investigation. It turns out it is a known limitation to that setup. My advice when selecting an OBD2 scanner is look at the requirements, if it uses a ELM hardware interface, FORGET IT!
To be more specific, I could only get data at about 1 parameter/second. Lets say you wanted to look at timing. You want to record RPM, Timing and Speed. 3 parameters means you would only get 5 timing samples on a 15 second run. 5 data points accross your 1/4 mile run is worthless! The Car Code scanner I use has a MUCH more cryptic interface. I've begrudgingly got accustomed to using it and still probably can't use it to its potential but it is MUCH faster! It records at like 5 samples per second (I think). I still don't get as many data points as I would like but it is usable. I tried to use the dyno feature on the Digimot - ELM based unit, imagine a dyno run - 1 gear (2nd) only lasts a few seconds so you only get like 3 data points on your dyno!
