AEV ProCal SNAP for 2019-2024 Ram HD

Take control of your 2019+ HD Ram 2500/3500/4500/5500 with the AEV ProCal SNAP module. This module customizes vehicles and optimizes fuel efficiency.

We have in our family a 2014 Ram 2500 4x4 Cummins pickup with 285 75R18 tires. The speedometer was recalibrated with an AEV Procal. Also, I used another AEV Procal on our 2016 Ram 2500 4x4 35 12.50R17 tires for its speedometer recalibration.

Have this as well. Also changes the low tore pressure warning if you go bigger/run lower pressure.

Unfortunately the AEV Procal is overpriced for what little it can do. AlfaOBD and JScan are better and cheaper.

Yea, can't see spending on a one trick pony like AEV or the OBDGenie built for specific upgrades.

Does AlfaOBD or JScan work on a 2024? I know very little (and by very little, I mean pretty much nothing) about either of those apps or how to use them. But it was my understanding there is no getting into the computers on 2023 and later trucks? Which app is better, or more importantly, easier to use for an old schlubb who is braindead with technology gizmos? It looks like JScan is free for Android, AlfaOBD is $50. Where do you fellas get the little plug-in module to make them work?

*I see Alfa shows up to 2023 but does not list 2024. JScan only shows to 2022.

Anyone?

 

[Brutal_HO]

Yes, they work on 2024.

No, JScan is not "free" you need a VIN license.

Either app can be installed and most read only ops work, but you need a license to write any changes.

The info for recommended OBDII reader and bypass cable is in the first post of the AlfaOBD thread.

Thread 'AlfaOBD'

Aug 22, 2019

Has anyone played with AlfaOBD on their 2019 HD's yet? I'm curious if anything is accessible to "change" and if it just works. There is lots of different info out there on other forums, but i haven't found anything in regards to the 2019's.

EDIT: AlfaOBD does work, here is the what is needed to use it on 2019 and newer HD Rams:
- The Android app from google play store, or windows download from AlfaOBD.com. (Windows version strongly recommended) (AlfaOBD is Windows/Android only)
- A Bluetooth interface such as OBDLink MX+ or OBDLink LX (cheaper than the MX+ if you don't need iOS support...

Thank you, kind sir!

Do you (or anyone) have a preference, AlfaOBD vs. JScan for ease of use for the technology challenged?

JScan probably easier and it can program FOB's if needed.

IIRC, there's some things AlfaOBD can do (radio module?) that JScan can't but I doubt you'd have any need for any of that.

If you're Android (or have a windows laptop or even virtual windows on MAC) you can always use AlfaOBD if ever needed. I have both as I got JScan to program spare FOB's.

At the risk over over-mentioning our expert @Jimmy07 would know all the intricacies. (We should make a table).
