Thanks,I set the 5v had it at 5.15 I’m heading back to the job today to fine tune for the most part. I uploaded car 2 parameters to car one and changed them accordingly for car Id and car specifics. But ended up changing car 2 to master and car 1 to slave to fix the hall call issues and car was running but they’re complaining about slow doors which I am going back today to look at.
