For those who are using dataloggers, just wanted to find out your feelings are on them? Are the programs easy to run, did it significantly help out in tuning and viewing data on your cars??
After reading the overview of it on obd2.com, it looks pretty tight. If not for the fact I can concentrate on the road during tuning sessions. Kinda dangerous and impractical to be looking at and processing the info from 4-5 different gauges while running down the road at 90mph+ during road-tunes, ya know....
