DiabloSport OBD-II Port Cover Reviews


Purchased The Diablo I-1000- for my 2010 Mercury Grand Marquis

Reviewed By Marcel M (PHOENIX, AZ) Reviewed for a 2010 Mercury Grand Marquis —4/5/2014 12:49 PM

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. :)

The Diablo has several options to choose from. I like the option the most that i could deactivate the active fuel management on my automatic Camaro SS.
