Okay, I got all of my supplies in. Has anyone installed the "double bypass cable" that AlphaOBD says is necessary to get around 2018+ security updates? I bought the double bypass, and the instructions are for a Dodge Charger with a trunk mounted battery, I think. I've also got all of the colorful cables and two different OBD2 modules. And AlphaOBD software for PC.
Honestly, the 12+8 bypass cable feels like it would cause less potential problems down the road and is dead simple to install. On the 2020 all I did was lay on the driverside floor, and looking straight up into the footwell you can see the module/plugs plain as day. The first time I popped it in it took maybe 2-3 mins, now it's a 30 second process.
With that said, tapping into any one of the various star connectors is a tried and true method that is applicable to most FCA cars. Not to mention it's far more discreet than having a 12+8 cable hanging down.
For anyone who is shopping for an Alfaobd / multiecuscan OBD2 adapter, make sure to avoid (for now) the BBFLY GX / Vgate Vlinker MC/MC+ devices. While they are damn near 1:1 hardware clone of the older revision 2 Obdlink mx (even reports running stn1151 v4.3.2 firmware!) along with supporting all of the same at/st commands (along with their VT commands

) Alfaobd doesn't have the correct initialization commands to get it to work properly.
Weirdly it'll access anything that requires the blue adapter but nothing else no matter what you set in Alfaobd's adapter config. It's quite tragic as this adapter can be had for as little as $30 and has a technically superior instruction set that allows for something like 50-60+ completely user configured can protocols, down to custom iso rules. (there is a datasheet on the bbfly site under the downloads area with all the info)
I'm sure someone out there that is more knowledgeable than I am when it comes to using an elm327 clone via command line would be able to figure out how to get it configured for Alfaobd. Hopefully, by making this post (and therefore adding a couple more google results with actual info about this device) it inspires someone to take a closer look at the seemingly first solid obdlink mx clone. I'm fairly confident that if I can get the obdlink firmware update tool to stop crashing that it could be flashed to a 'real' obdlink at the expense of losing the VT instruction set.
