I am using hypertech. Are you saying it is the reason for my b222a code when I go above 2705mm in alfaobd? If so I'm taking it out.

If you have an air suspension you might have to "write suspension height values" and then "set ride height" under "suspension" in alfaobd. I am not certain of this, but if you ask one of our resident guru's in a pm they would likely know for sure. I know I have gotten a lot of help on here from...

I'm limited to 2705. I can't get into the parking module and I truly believe that's where our parksense unavailable is coming from.

Anyone know if the "vehconfig 7: traffic sign information feature present" works when enabled in alfaobd?

So I got the bcm to take 2700mm and I put that into the hypertech as 33.84 for original tire size. I put in 34.90 for new tire size. At 70mph via gps the adaptive is reading 68 and the actual speed is 71. If I could just get a few mm more into alfa I could get everything to match. Real speed...

My 2022 bighorn had ECS and EBP in plant mode after installing new HCU and ABS module as well. ACC is now fully functional. I have a speedometer not matching cruise speed issue though. I have 37x12.5x20's that Sherrod did a speedometer adjustment for when truck was new and now I just have to...

I have a 2022 1500 bighorn with FCW+, lane keep, Pedestrian Emergency Braking,etc, but no ACC which i am trying to add. I dont want to start the add without having a backup. I have tried everything I can think of to get alfaobd to save a backup of my bcm and it will not work. I click on "view...

Frequency and voltage have to match to parallel two electrical sources. In parallel you are correct that it would remain 12v but there is a lot more to running two alternators in parallel than just wiring them together. HD forum would be best place to ask.

The explanation is very long so to make it short...12v + 12v = 24v, 24v + 24v=48v. A component will only demand amperage needed unless there is a short. Without a fuse to stop it from demanding too much amperage when it shorts out, it will catch fire. I really wouldn't recommend trying it unless...

Wow, thanks a bunch. I think I now understand why some get lights and some don't. I really appreciate you getting back to me on that.

I only ask because I'm about to add acc in a couple of days.

Under 2022+ did you try [BCM....car configuration change---near bottom of list...vehconfig 8: Pedestrian emergency brake (PEB) present: yes]?

Making a backup is one thing I am having a little bit of an issue with, but I will make sure I figure it out before I proceed. Thanks again.

Yep, that's what I was going off of. Thanks for confirming the info there is correct. Really appreciate it. Glad alfa put in the search option or I would be boned. Lol

I might need a little help next week when the last of my parts come in for Adaptive Cruise Control. I am going to be using a used abs module and hcu. Seems straight forward from the posts on here, but it seems some of us are getting lights on the cluster and some are not. Could just be different...

Actually realized there is a vin posted from a Laramie early on in this thread that has advanced safety group. 1C6RREJT4MN628940

I will try to get you a part number tomorrow.

Also a shout out to tbd0021, also a major source of information. I really want to thank everyone though. There are so many people on here that have made me happy to have bought my first Ram. Been a ford guy my whole life until now. This seems like a great community to be a part of.

2022 Ram DT Big Horn. I have added auto dimming high beams with just changing 3 settings in BCM, no additional parts needed. I will be adding adaptive cruise control, Rain sense wipers, passive entry, blindspot monitoring and 360 surround view cameras. I will put up YouTube videos of the alfaobd...
