Cummin Diesel Engine Exhaust Brakes auto on with ignition

[Atty]

Does anyone know of a way to set the engine brakes to default on when starting the truck?

Whether it be using a standard menu through EVIC, radio unit or using AlfaOBD?

Would love to not have to remember to turn this on all the time.. I never drive on icy roads so I don't have any concerns about forgetting it's on and if there's a time when I need it off I'd rather select it off then have to constantly select it on.

Cheers!

Nope.

Most have reported if you have it on and a trailer plugged in, it will retain the selection. Sans trailer, cannot be set to stay on.

 

[Atty]

Yeah from what I read in the manuals I couldn't see anything. Was more hopeful that ALFAOBD would come to the rescue.. I've already looked through the options and couldn't see anything mentioned..

I wonder if the NAVIKS unit could be programmed with this feature as well... I'll mention it to RBarrett to see if he would be willing to ask about it

Wondering out loud if a truck/trailer receptacle tester would fool the computer?

Wow. I was thinking that same thing 40 minutes ago as I left to go pick up the GS from school and had to hit the button.

Probably my #1 most wanted improvement. If they are worried about ice braking, they could unlock it based on temperature at startup. At least some part of the year it would work great.

a tune would remedy that as well, if you were so inclined.

A tune is something that we definitely have considered doing.. what sort of tune would give this option? I've done a little research into it and seen multiple ways that I can achieve a tune. I was thinking about something along lines of an ezlink tuner and say duramax (or similar). Will have to search the forum for any threads on tuners. I notice that lots of the powerchips are for RAMs only up to 2018. I like the idea of plug and play devices versus having to take it to somewhere..

 

[elephantrider]

any tuner can modify the eb to stay on.

And your thoughts on the duramax /ez zink tune? From my searching through the forum for available tuners, I see you have a tune of some sort.

Both the CTT and Duramax are similarly priced. Are there any others you know of that you'd recommend?

 

[elephantrider]

I use efi live exclusively. is that what you're asking?

 

[Atty]

OK yeah I was asking what tuner you have/use and also whether you knew much about either of the above.
Do you tune it yourself or do you have a tuner company that you use and you flash it yourself? I'm not up for doing my own tuning.. That's a rabbit hole I don't go down..

 

[elephantrider]

I use a well known cummins tuner that sends files to me, then I flash it on my local efi live. haven't ever used anything else besides a smarty way back in the day.

 

[Atty]

Ok great to know, thanks for the info

I wired a 7 pin trailer plug with a 12 ohm-10 watt resister, wired to brake and ground and keep it plugged in. Truck thinks a trailer is connected and keeps the EB on all the time. You can still adjust between auto and full. My brother used an 8 ohm-10 watt resistor and gets the same results.

Good to know you can fool the computer to keep it on, does it default to the Full or Auto or what you last had selected?

 

[elephantrider]

what you last selected.

Well, there you have it. Proof positive.

Cool trick.
The question now is why doesn't the transmission stay in tow mode when trailer is plugged in?
My #2 most wanted improvement

My 2013 retained either setting. And 2020 hasn't allowed for much towing.
