One thing that would be really nice if we can choose something for our Register members, so we can share files across the board. I am not sure there is an ideal setup that will please everyone, but at least for DE purposes, we would need something reliable with support and easy to use.
Frankly, the RacePak unit I have, has been very reliable, almost fire-and-forget type if you don't worry about the TPS, RPM and other electrical connections as options, and their support has been superb. When I have an issue with the software, they remotely connect to my laptop and do things for me
What is not so nice is the Datalink software, cumbersome and complex at best.
So now I am looking at this:

The software seems to be very good as I hear, the new version, cheap, auto video/data integration and reliable ODBII connection via ODBII cable, so single cable, you get all. It is still lacking yaw readings, but for the price, I can live with it.
