Well i've had my x-cal2 for several months now and i have been running my 87 perf tune cuz of gas prices. I filled up on 91 and came home to load the 91 tune. I plugged in the x-cal, and nothing. no screen lightup, no text, nothing.
any idea??

 

From what I've read, it's your fuse for the cigar lighter......

good luck

going out to check it. this is GAY

 

I heard one other poster having that same problem and it was indeed the cig lighter fuse? Whats up with that, I would think that would be a one in a million unless people are using a ton of accessories powered by their lighter ports? Go figure!

 

maybe they are just really serious smokers and have modded their lighters?

 

cancer merchant, cancer merchant!!!

 

well the cig lighter fuse was burnt so i replaced it and i loaded the tune. I never use the cig lighter though. weird

 

This is very typical, and is just because the cigarette lighter fuse was blown - and that happens because people plug things into them that take more power than this circuit can handle - like call phone chargers, GPS units, radar detectors, etc., or simply don't use proper procedure when connecting or disconnecting such devices & cause a mini-spark that they can't see but that blows the fuse.

So there's nothing wrong with the XCalibrator whatsoever - it was simply a blown fuse on the vehicle.

The cigarette lighter fuse covers the OBD-II port as well, so if it's blown, you can't get any power thru the OBD-II port, either - thus anything you plug into the OBD-II port cannot work. Sometimes technicians cause this by how they handle their diagnostic gear, too - thought that's pretty rare, it's usually the vehicle owner who has plugged something in that required too much power, or did it in an improper sequence, had a key on when they plugged the unit in etc., something that caused the cigarette lighter fuse to blow.
