So I was bored at work last night and I was looking at "pen computing magazine". There was an article in there about the AutoEnginuity scantool. This program can be installed on a laptop, pocket pc, or palm devices. It attaches to your ODB-II and acts as a code scanner but it also has a program with it called speedtracer wich acts as a dyno, tells you your 1/4 mile time/MPH, 1/8 mile time, ETC. They also have a website that tells all about it HERE . Anyone ever use this stuff or know anything more about it? It looks like it could be more accurate that the G-tech because it plugs into the ODB-II port.. What do you guys think???
