This cover is excellent quality, I am very impressed with it. It Keeps the Ford dealer from "re-programming to default" my set performance parameters on routine maintenance visits. Or at least it puts them on notice when they see their code reading machine will not plug in.... Then then the mechanic will check the work-order that they failed to read in the first place, and see I TOLD THEM TO NOT TOUCH MY PORT!this will change my parameters.They leave it alone and all is well with the world. :)

Lots of options

Reviewed By Kenneth F (HENDERSON, KY) Reviewed for a 2011 Ford Ranger —4/15/2015 4:25 PM

Really a nice device. I am amazed at all you can monitor with it. My main reason for purchase was to monitor the transmission temps when towing my 17 ft travel trailer. But I'm also monitoring fuel mileage and throttle position. I only gave 4 stars because the included velcro for mounting allows for too much vibration. Replaced it with a 3M Command strip refill.
