Ultragauge has 2 new versions.

1. EM Plus:

The UltraGauge EM Plus is identical to the UltraGauge EM v1.2 except for the following additions:

Readiness Monitors
Performance Measurements
Additional Wide O2 Sensor support to track Stoichiometric AFR via Lambda

In addition, when a trouble code alarm occurs, the first trouble code found is displayed during the alarm event. Previously, the menu system had to be used to view the trouble code.

2. MX:

The UltraGauge MX is identical to the UltraGauge EM v1.2 except that the MX has the ability to POTENTIALLY access manufacturer specific gauges. Primarily intended to access the transmission temperature parameter on Ford and GM trucks


I think I like the improvements on the EM plus over the standard version; MX is not an advantage to me, as we don't own Ford or GM vehicles...

If only the MX could read manufacturer oil temp for our e46s lol

That's Cool. I really like my UltraGauge.

I must be the worst procrastinator in the world, I was planning to get the UG a long time ago. But in this case, I guess it worked for my benefit:
I am gonna get the EM Plus: I like that it directly displays OBD ii code info instantly without having to fiddle with the buttons to see which code it is.
The Readiness Monitors and Performance Measurements are a nice bonus, too, if i ever need those.
