JB4 app only reading map after we did a code cleanup

Are you on the main page with the six gauges? Or the square map buttons? At the very top should be tabs for Display, Logs, Codes, and Settings, so you might be under Settings and need to hit Display.

If you're on the main page with six gauges, either tap or long press each one to pick what it shows. I think default is RPM, Boost, Water Temp, IAT, AFR, and Map. Maybe Trans Temp in place of one of those, but obviously you can pick whatever you want.
