Does anyone use this ecometer device on their JK? I would be interested in the instant fuel economy, and the digital speedometer. My thought is though, if you have larger tires, would it read right if you have installed a Superchip or AEV Procal unit?

Quoted about the device: "The Auto Meter Ecometer digital gauges offer four different modes that can be easily selected by the driver at the touch of a button - instantaneous fuel economy, average fuel economy, digital tachometer with instantaneous fuel economy, and digital speedometer with instantaneous fuel economy"

The factory EVIC seems to do everything except for instantaneous fuel economy, seems like alot of money to pay out to find out what you already know, JKs get crappy fuel economy :P

 

I use the torque application on my Android phone if I want instant mpg but truth to be told, my GTO has the instant mpg display and I end up changing it to the average display as I consider it more useful.

The instant mpg jumps up and down too much and becomes useless after a while, road conditions vary too much to get anything out of it. Also constantly looking at the display will become dangerous, I think that's why manufacturers are getting rid of it.

PD. Who the hell needs instant mpg on a SRT8, although as per the reading, 0, seems accurate! It looks like crap too.
