What ULTA GAUGE do you have ?

I'm looking to monitor auto trans temp , coolant temp and battery while towing my camper . Been to the products website , but no real answers can be found . 2008 V6, auto . Thanks

 

I have the blue and it doesn't tell trans temp.

 

I have a Scangauge II with a blendmount. It works really nice. I bought it primarily for trans temp. It's a little bit tricky entering the codes for trans temp from their website. The price is pretty much the same whereever you buy it so I bought mine at O'reilly. Here's a link to the Blendmount.

My Blue shows transmission temp.

 

my blue shows trans temp as well but it was a pita to get it to work. If I had to do over I would just get the other one with the cord (sorry I cant remember the model)

 

The Bluetooth model? How old is it ?

Maybe yours is newer because they added trans temp recently I think ?

 

I have the "basic" ultra gauge. It has coolant and battery. It does not have granny temps from what I could find after installing it.

 

MX 1.3 after entering configuration codes (found here on TW) it shows both trans temp readings.

 

My mx came out of the box reading trans temps on my 05

 

I didn't know there where two. where did you find the configuration codes?

I found mine in this thread 2012-2015. I see you are running an 08 I think the m-guage coding is different for those years or may be pre-loaded from factory. I purchased mine primarily to service my transmission however it is a nice out of the way display that gives you a ton of information. Mine is mounted top left of rear-view mirror that location works out perfect with the included wire length.

 

Ordered my Blue when it was first released October 2015. Originally the trans temp didn't work, fortunately they fixed it a short time later.
