I sent this question to the UG folks, "I have an EM plus V1.2 dated Mar 4,2014 in our 2006 Jaguar Super V8 and would like to know if this car, built while Ford owned Jaguar, would benefit from the MX 1.3 version Ultra-gauge. It is not on the list for MX preprogrammed cars, but there are several Fords listed there. The engine is a 4.2 liter supercharged V8 and the protocol (as listed on the EM Plus setup) is 11-Bit CAN. Are there any useful gauges available on the MX 1.3 for this vehicle? I'd especially like to know if there are any air suspension codes or information on this same system as that used by Ford in the Lincoln LS. I need another Ultra-gauge for another car and would buy the MX and swap it with the EM Plus if there are advantages for the Jaguar; otherwise I'll just buy another EM Plus."

Their answer was to read the FAQs for the Ultra-gauge MX, which I had already done, and the only Jaguar listed in the UG gauge availability estimator is an XK8 convertible with a 9141 protocol and not CAN 11 bit. Here's what they show for "pre-programmed" vehicles. http://ultra-gauge.com/ultragauge/TEN/compatibility.htm


The UG MX FAQs say "...It takes automotive enthusiast to reverse engineer and make codes available. The best source for codes is an automotive forum specific to your vehicle." The UG tech folks just refer me back to their FAQs page, so I am asking this group if anyone has tried a UG MX on an X350 and if any of the "Pre-programmed" Ford choices offer any advantaged for a UG MX over the UG EM Plus.
