Let's build what the Trucker wants... W900 with DD15 @525

It’s been over 3 years and the people who have a whole business built around it haven’t cracked the code yet.

 

They need to start building their own dashes maybe? I don't know anything about it. It still baffles me that one wire can be used for numerous functions because of different frequencies - like being able to get internet, phone, and tv all on one wire, and they all work at the same time.

It will also be interesting if emission laws are relaxed in the near future. I think it is probably fair to say that enforcement will not be as stringent for the next few years.

 

It's not different frequencies, but each information packet has an ID attached to it. So everything on the canbus sees everything, they can just ignore what isn't for them (or read it, that's why your ELD can read fault codes) That's why when you change a part that's on the bus, you have to program the computer. It needs to know the ID of the new part so it can talk/listen to it.

 

I'm still in the dark ages! With 2 out of 3 of our trucks we still communicate with a steel rod between my and the engine!

To your point though, I still think that there will be a solution to communication issues between Cat engines and Paccar's digital dash - at some point - if there is enough demand for it.

 

Even before the digital dash there were certain functions that Elkhorn couldn’t access in some of the cab modules. They’d do the swap and have to get the trucks to Peterbilt and have them make changes. The big bosses that run the group of local Peterbilt dealers cut them off from doing that before the digital dashes.

As far as emissions, I could see things getting relaxed in the future but I don’t see things going backwards that manufacturers already have in the pipeline for meeting the 2027 standards.

 

I drove one just like that early in my career. It was a long legged old truck and rode really nice

 

It’s not really anything to do with manufacturers or the right to repair stuff. Part of the greenhouse gas rules was that they have to use technology to make the engines more difficult to tamper with.

 

The X15 for me has been a great fuel saver. At 110-129k gvw she’ll still average 4mpg’s a week. Some weeks better than others. But it has a lag that I can’t stand. Not sure if it’s the way the pedal communicates with the ecu or if it doesn’t eat the amount of fuel I’m thinking in my head she should be eating at full throttle. It’s got the 605 in it but doesn’t compare to the kind of throttle response/power on demand my 550 Cat had.
Haven’t ran into anyone using PDI or bullydog products yet to get any feedback on how good the tuners work.
