I finally got around to making some changes with forscan but as soon as I connected it to the car and hit connect I got this error message. I’m currently tuned with zfg if that makes a difference on the code I type in? Thanks

You'll have to flash it back to stock, make your Forscan changes, and then reload your tune. Flashing back to stock was the longest part of this process for me, but it was definitely worth it.
