Finally got my UG yesterday and installed it in the car today. Apparently, the gauge does not support my my 2000 Suzuki Swift, or the Swift is not equipped with more than some Suzuki diagnostic ODB2 port layout.
A real bummer! Ironically this piece of equipment that was going to save me some money, actually ended up costing more than it can repay! Well, theres a new car arriving at the end of next week, hopefully that one will work!
