AlfaOBD

It’s under CBC features in car configuration change called led front park/marker lamps. Good luck. I had the diode dynamics switchback boards and went through 5 sets of drivers they kept sending me before I threw in the towel on those things. I tried everything.

Mine are already set to led from the factory since I have the factory projectors. Thought about adding a PWM (canbus module) on the park lights before the Diode connection to see if it would regulate the voltage before the Diode module. We will see i guess.

There seems to be a general agreement that prolonged idle of the Hemi leads to lifter/cam problems. The 13+ 6.4 Hemi in the 25-5500 trucks seem to have a high idle function like the 6.7 CTD.

Has anyone figured out if it can be activated using Alfa? I emailed Alexey twice about it but haven’t had any response.

Hopefully you have better luck than I did. They had me trying every possible combination of cancellers, resistors, led settings, and every time I thought it was good to go, a week later the turn signal circuit in the driver would fail, or the park circuit in the driver would flicker and fail. It was always something.

On the 6.4s, the high idle is only a feature for the cab and chassis trucks, but you would think it could be enabled on a regular 2500/3500. I looked before, but I don’t see anything resembling the feature in the alfa when connected to my truck.

Thanks for your help. I've already thought about using relays and just use the Diode module for the trigger wires, but if leds are flickering, just wondering if it would cause a relay to chatter. And obviously would need to look at output voltage for each. I'm sure they all don't get a constant 12v (or use the relays to power the Diode module, trigger from the factory wires (again, wondering out relay chatter), and let Diode module work as normal...).

When they worked flawlessly for me (for a week), I had the turns and parking lights set to LED, and I had the diode dynamics canbus cancellers wired into the factory wiring before the signal hit the switchback drivers. It was the passenger side turn signal that ended up failing inside the switchback driver. It could have been a fluke for me, but may be the solution for you.

What year and engine is your truck?

I wonder if the trick is to activate pto or something like that? Maybe one thing opens up another set of options.

High idle uses the cruise control. My 2500 Diesel came with it activated. I do believe there is a setting in there for that. But you also need to have the parking brake on for it to work.

Mine is factory set on 2500 2016 Diesel and I don't have to have parking brake set works fine without it..just my info..but yes hit cruise on then set and up she goes!

I just came over from a 6.7ctd and on that one you didn’t need to have the parking brake set for it to work, but I haven’t tried it yet on the 6.4. I guess I’ll try that. Thanks

I found a place in the engine section (2014 2500 6.4) on the Alfa that says “change rpm”. Is this referring to changing idle rpm, and is it permanent or a temporary “test “ type thing?

Anyone every mess with the speed govern. My truck tops out at 170kms (Canadian truck) any settings in Alfa to increase that? To perform such speeds legally of course...

that is normal CUMMINS behaviour even SEMI trucks work that way
that might be Cummins and NOT RAM feature

There is a way, I don't remember what had to be changed. I believe it was in the ecu settings. I know someone on cumminsforum figured it out. I don't recall if it was posted in the alphaobd thread or if it was a separate thread

If I remember when I get home my rebel is set to 255kmh I could dump my settings and you could take a look if that would help but that wont be till next friday

My truck is set at 255km as well but still governs our at 170. Must be another setting somewheres else to change the govern

I think I found the forum you are talking about but they were only talking about changing the cruise control max speed

Being a 13 you can easily buy a tuner and basically delete the top speed governor.

True but being as I already have the Alfa obd I figured I’d ask

 

[PNUTLT1]

Hopefully someone can answer this;
before i got the alfa, my cargo lights would stay on my ram when i was driving around.
I have bright red LEDs on the cargo, sorta like additional reverse parking/fog lights.

Now the cargo lights stay on only on park with the truck on.
If i have them on and put the truck on drive, they turn off.

Anyway to keep them on at all times?
