Did not work for my 1997 e350 v10, might work on newer things that already have all these gauges, so it's pointless, oh and it doesn't conform to killers, its flat pillars are round.

PROS: Provides the information I need. Allows adjustment for the speed a few percentage point above or below the speed it shows by default. Readout is a decent size for such a small device.CONS: I have 2 of these, and the maximum brightness is noticeably different between them. One is bright enough for a very sunny day, and the other is not. One of these shows the coolant temp jumping between 190 and 210 and back down to 190 each time it refreshes (every couple of seconds). I don't think the coolant can cool that quickly. Not likely correct, but if you average it out (in the middle), it's probably reasonably close. I guess if it shows 215 or higher consistently, then your car is in trouble.

Size, obd2 connection, and listed features look good on paper. Never worked right with Toyota 86 however.While the display looks good, the unit I got repeatedly reboots itself, lists boost pressure in kPa even though I changed it to PSI in settings, never accurately displayed boost pressure at all, and didn’t even display MPH during most of my tests … just sat at 0mph. In factThe only thing that appeared to work was battery gauge which fluctuated between 12-14v but at least it was reading something.Really wanted this device to work, and perhaps I got a lemon, but it’s going back.

Great for other important functions, but todo provide info on supercharger
