I’m looking for barometric pressure sensor.

I unplugged what I believed to be the barometric pressure sensor and the I got another trouble code that was boost related and had the same description “ voltage above normal or shorted to high” So it definitely sounds like a bad or disconnected barometric pressure sensor. But where the heck is...

I’m getting a fault code 108 3 Barometric pressure. Voltage above normal or shorted to high source. I was planning on replacing the sensor but cannot verify the location of this sensor any know where it is? I believe the boost pressure sensor is the same part and I don’t want to replace the...

That’s an interesting thought about using the trip to get averages. Thanks, Still working on the cluster colors. The green numbers have been changed to white and enlarged. About 5 hours into programming also changed engine torque to barometric pressure.

Not sure how accurate that 7.5 average mpg is. It was there when I first plugged the blue fire up. Not sure if that’s over the life of the ECM or what. It hasn’t changed and I can’t figure out how to reset it. I put a new ECM in it 6-7 years ago.

Just returned home after a 120 round trip to Caterpillar where they programmed the ECM Speedometer parameters. Here in Florida driving long flat straight roads with no wind adjusting the cruise control speed every ten miles or so and watching the Bluefire instant fuel consumption. It looks like...

Maybe I’m the unlucky one.

Machining them with a matching radius would be difficult.

Hike, did you run constant 12v or ignition 12v for the BlueFire port?

I don’t know if this is the best thread to post this on, thought it might not be seen. Eco Hub arning! You cannot remove or install your brake drums after you finish the eco hub installation. To do so you must modify the aluminum D shaped plugs by grinding the high points off. My 5” right...

Go back to the incandescent lights. They are 12 volt and can purchase bulbs anywhere.

I thought maybe the cab tilt?

Simple enough! Thanks for all the input.

I finished the eco hubs install. Everyone talks about doing a transmission relearn. After an hour searching the closest thing I can find on that is in an Allison manual that briefly says to just drive it through the gears. Please, Can anyone give a better more complete description of the relearn...

What do you guys think of TES 668?

By the way what is recommended fluid fiter ad change recommend using synthetic DEX?

Thanks for that great information. Fortunately after I removed my drive shaft and gave it a closer inspection it wasn’t the seal leaking it’s was coming from behind the nut. Yesterday I addressed that. removed the nut and washer and discovered NO silicone and a steady drip seeping out between...

Filling my new eco hubs with gear oil I noticed it was pressurizing. Lead me to check for proper ventilation. While trying to find where it vents to is a lot more complicated than it should be. After figuring it all out I figured I should share this information for everyone. A quick drawing...

Easy enough! Thanks for all the help. I’m currently working on changing all sorts of stuff on my truck.
