Are you waiting on the CAT system or one like IFSkit.com?

Reviewing the CAT documentation I have located so far states that in North America Low Sulfur Diesel and Ultra Low Sulphur Diesel grades 1 and 2 meet CAT's specifications and to buy from reputable fuel suppliers. The operation manual for your engine has more specific information, (available for...

Slowly progressing. Painted the interior doors two tone: taupe and white. Hoping to start going back together next week—

I am no machinist, though it struck me the same way. The gouges are running perpendicular to the rotation, not with it. Those didn't happen inside a spinning PTO–

Check this thread before buying? Starting at fifth post by @MatthewWBailey—

No computer? Don't tell Rick =)

Our 3126b originally configured at 275hp does not have the barometric pressure sensor. My casual studies suggest a 330hp 3126b does. The code in our unit showed after flashing the ECM for 330hp. The pressure reading is unchanging. Perhaps we had the code before, though I am pretty sure not...

As I recall, if you don't have 15, ECM has a default static barometric pressure. If you recently reprogrammed ECM it is looking for sensor and not finding it, (error code), though still using statice default pressure— I believe the CAT part numbers are one number different—

Perhaps off topic: C40? Learn me up, please—

When I look at our ECM using Dearborn or CAT ET software our's shows how much fuel used and mileage all time. So, in Bluefire our Average Fuel Economy is only 4.6mpg. I don't wish the reset the lifetime numbers, though not entirely useful. In Bluefire I have tried using the trip distance...

Your Average Fuel Economy for the life of the truck is 7.5mpg!?

Most of us prefer a tight fit—

I did ignition, though as I am cleaning up the cab interior and adding another fuse block for power doors and windows on the driver's footkick, Bluefire will be constant, too—

I was looking for a photo with the drums off, before I pulled the wheel hub plates though no luck. I am certain when we did the rear axle seals we pulled wheels/tires, drums, then hubs. We didn't pull the EcoHub covers and plates before pulling the drums. Here is a detail of a rear hub off...

The challenge in a small space is that as the number of air changes increases the efficiency drops. Balancing the air exchange rate is important, though as long as you heater/cooler can maintain comfort the only 'problem' I see is a reduction in the energy savings—

As I recall 'A' is ground, 'B' is power. I clipped the red wire on one of the "Y" connectors and attached to 12v feed. The Bluefire adaptor hasn't burned yet—

1— I agree. As yet I have not taken the time to learn the backend of the Bluefire software; 2— We have a 3126b, no idea what Bluefire sees from the C7, @Third From Texas has a Bluefire adaptor The RV OEM apparently wired the oil pressure sensor to feed the J1939 system. According to the CAT...

We have a 9 pin adaptor. Our data port is 24v. We bought a splitter and replaced the 24v feed wire on one with a 12v feed. Now we have two 9-pin ports at our left knee, a 12v and 24v. I was hoping to use the bluefire to create a glass dash, though our ECU/ECM systems and the bluefire share...

Bluefire makes a 9 pin adaptor and app to read various systems from J1939, J1708 and CANBUS. We have one, though our military systems offer more a teaser of information than enough to build a glass dash. You have to convert or add a 12v connector to the connector at your left knee to use the...

I agree CAT's suggestion surprised me, too. Though that is a quote from their spec sheet for 'balanced performance and fuel efficiency'. Attached sheet to post #17. Our M1078A1 with the 330hp tuned 3126b doesn't like 7th gear at 60mph. We have to go faster than we wish to get into 7th, then...
