Yes. That would be great thanks.

AlfaOBD help
I am asking for anyone with a hellcat and who uses AlfaOBD to please either post a BCM read (preferably) or screenshot from your BCM read of the chassis type of your vehicle. Please include the model year, model type (Challenger/Charger), and transmission (manual/automatic). If you post the BCM read make sure to block out your VIN#.
I'm trying to test a theory and find a solution on a couple things. Particularly, I have a 2016 A8 Challenger Hellcat and I upgraded to a 2019 Uconnect radio so I could get Android Auto / Carplay plus the newer performance pages and faster processor of the newer radios. I'm very happy about the upgrade and everything works options wise except launch control is defaulted to 1,000rpm and the rpm cannot be adjusted. This is pretty much the case with everyone I know that have a 2015-2016 vehicle and upgraded to the newer Uconnect 4c radios. I have done a fair amount of research and suspect this can be fixed via a command using AlfaOBD. I appreciate anyone that can help.

I have a 2016 so I did not have to replace my BCM. I also know several others who have 2016's and did the upgrade and are experiencing the same thing with their launch control so I don't think that is the case. That is why I am hoping some of the other members can help out and post a copy of their BCM read or at minimum the screenshot of their chassis type. I'm particularly interested in 2017 and up but I would like to compare 2015-16 also as long as the reads are from an automatic transmission vehicle. I could be wrong but I strongly feel the launch control issue can be resolved through a BCM command via AlfaOBD.Also, I’m curious here. Did you try driving 500 miles yet? You replaced the bcm, programmed as new, and the radio. I’m wondering if the 500 mile lockout for launch control was somehow reactivated/reset? Maybe not, just throwing ideas out there
Thanks I'm going through it and will be testing a couple things and will post any findings.After looking at the log file there is a bunch of stuff in it. It didnt want to attach, Ill see what I can do. It has HOM and Chiller in there. I wounder if I could turn on the chiller function and get rid of the toggle switches Im running and let the bcm do its thing. I had to change the .log to .txt to load the file.
Did you do the radio upgrade?Alfa enables or disabled the functionality, has nothing to do with rpm limit
I agree I'm not a huge fan of it but I'd still like to figure out the issue post upgrade.Launch control is useless in these vehicles anyways
And I greatly appreciate it. I'm hoping to there is a few more members with 2017 and up Hellcats that can post their BCM read. As I mentioned previously, z automotive suggested it was because I used a 2019 radio and don't have a 2019 BCM but I'm not totally sold on that idea and would love to compare a few 2019's so I can see if there is any different commands for launch control.After looking at the log file there is a bunch of stuff in it.

1. Bud, not sure if you meant it but you are coming across a little arrogant in my opinion. You say you have done a lot with Alfa, good for you. 2. I did ask the same question in another forum because maybe a member over there also has a good idea either from experience or otherwise and wanted to contribute something useful to the discussion. 3. I am very pleased with the radio upgrade and would do it again in a heartbeat. The Pros far outweigh any Cons in my opinion and frankly I could care less about launch control and I am certainly not putting the old radio back in. I just wanted to experiment and possibly find a solution to the launch control staying at the default rpm that I could share with the other members of the forums.I’ve done way more than anyone has done with Alfa for these cars, and that’s a fact. That being said, no - no need to. And my launch control works great
I am still looking into this but haven't had the opportunity to test some things due to taking a good hit from Hurricane Ian so I'm just getting back into the swing of things. Luckily the hellcat survived unhurt. I hoping over the next few weeks I can play around we this and post any updates.
