I guess what Im looking for is more information on the engine... misfires, historical information (which is a big one), ignition timing advance, the chrysler entended codes (which they are going to release soon).
Example of why I decided against the scangauge II. Driving down the highway the other day at 70MPH, had a loss of engine power, just for a brief moment. I didn't catch to see if my RPMs went down, or it was an issue with the fuel system, or anything. It didn't throw any engine codes, and has not happened since. But once was enough for me to raise my eyebrows and wonder what happened.
Since I always travel with my laptop, i figured, why not plug it in and let it monitor everything it can and if something happens like that, i can always go back and see what happened in the historical info.
I might get the ultragauge since its under 60.00 to supplement the ScanXL.
Does this make sense or am I just being paranoid about my Jeep?
