I saw a guy on here a number of months ago with a device hooked up to his xj that showed everything from his speedo, water temps, oil temps etc. But for the life of me I can not remember what the product was called. I think they ran fairly cheap too maybe $70 or somewhere in the neighborhood. Does anyone have a clue what i am talking about? Haha, thanks and sorry for my short term memory!

 

I think a lot of guys use the scan gauge, but I never have.

If you have a decent smart phone you can buy a bluetooth obd2 reader and get a free app called torque that lets you read quite a bit of stuff.. you can also pay $5 and buy the torque app that's even better..

Heres the link to the one I bought..
