I bought the Ultra-Gauge EM which is the newest model, the only difference between the EM and the original is the number of gauges and the EM also does metric.
If you have the original you can have it upgraded.
I installed it last night and set it up, it has 8 different screens that you can set up and scroll through either manually or you can program it to scroll automatically.
So far I really like it and I highly recommend it, I paid $82 with shipping and there is a $9 mail in rebate.

 

very slick - how does it calc mpg on a D1?

 

It uses the MAF sensor and road speed to calculate MPG.
As you can see it says I averaged 1333.6mpg which is obviously wrong, move the decimal 2 spaces to the left and now you have my actual MPG for the 32.7 miles that I drove today.
I need to read the instructions more to figure out how to move the decimal.
I REALLY like it.

 

Explain how it gets the data? Dose it plug in to the rovers computer?
Thanks.

 

Yes, it plugs into the OBDII port under the dash, the same port that is used for checking trouble codes when the check engine light comes on.

 

Can it read and clear codes, including 3 Amigos?

 

Yes it can read and clear trouble codes, no it cannot read ABS codes.

 

Dang, you've got a light by your shade tree...

 

Buzz: You just need to wire your tree for 110...

 

Thats not my tree, thats the neighbors.
I dont leave my lights on 24/7/365 like they do, I only turn mine on when needed.
It actually pisses me off to see their porch lights on at 1:00 in the afternoon in July when its 100*F out and they dont believe in global climate change.
They dont recycle, they leave lights on 24/7/365 yet they are hard core Christians who think God will just take care of everything.
Do whatever you want, God's got it under control.
Sorry, rant over.
