Do you have the bypass cable?

I do. I am pretty sure I connected everything properly and I am getting an ISO error saying it cannot connect to the ECU. How did you connect the bypass cable to the CAN blocks. I want to make sure I did it right. I followed the directions Kaodtech provided.

I was able to force through using the MY2020 Body Computer to change my tire pressure thresholds. However, I have not been able to save my baseline settings to Google Drive.

You can ignore that message. I contacted AlfaOBD about that same message, and this is what Alexey had to say:

Subject:Re: Unknown ISO code

The message means that the ECU is not in the app database
yet. I'll add the data in the next release. ISO code is not
relevant for RAM, it's OK that it's empty.

Best regards,

I had the same issue today with my 2021 using Windows. I contacted Alfa OBD and was told to use it and it will work. He is working on the 2021 models.
 
Hello, All i know its like beating a dead horse by now. I have a 2019 HO DRW i used Alfa for a few changes. Most worked fine i tried to figure out how to fold mirrors on lock never did. Well i tried to remove speed limiter and well now at 70mph it just falls flat. I changed from Engine & body computer and tried to load from saved file and it just says ecm failed to load says wrong parameters. ive tried for many hrs and just cant seem to figure out how to just set back to factory settings. Thanks Bill Woodard

I hate to be the bearer of bad news, but in every story I’ve read of someone managing to bork the speed limiter with AlfaOBD the only fix was a new ECM.
 
I will keep trying at one point i had it to a MAX of 45mph. then kept trying now im up to 70. i thought there was a easy fix thank you for responding.

If I recall, mine is set to 500. It has to be in kph.

FYI, this doesn't actually remove the 102mph limit, only a tune can do that.
 
@John Jensen has first hand experience with this. I believe he reprogrammed his ECU through his dealer and it did not fix the issue, I think he has a new BCM on order to see if that fixes it.

Ok i figured it out. i just came back from a test drive got her to 104 but i think thats red line anyway.

engine control module >2018+ > max vehicle speed> 164> worked.
i tried from 100 all the way through 164 for some reason its not the correct speed? 140 = 70mph hope this helps anyone its NOT in body control its in Engine
 
For anyone else that comes into this issue. There are two spots you can "set" your max speed.

One is in the body computer and it tells you the maximum setting is 500 (all these settings are in km/h).

The other that some people have messed with accidentally and forget about us in the engine computer (still accessible through Alfaobd) and that speed setting is finicky. It doesn't tell you what the maximum setting you can set is. The highest I could set it was for 164 which is about 102 mph. Anything above 164 gives an error and won't let you change it.
This is the one many people change and don't realize it's in kmh not mph.
