Unfortunately the IMU is required. Most of the steering correction is from the gyros... really the other sensors just correct the small errors in the gyros. Without gyros, the turn rate would have to be emulated and it would never work very well
The next version will support more pilots. For example the wind pilot does not use the compass sensors, it uses only wind sensors and gyros so compass errors/distortions wouldn't affect it. It would be possible to make a pilot that only uses gps and wind or some other combination but I don't expect good performance.
I'm concerned about these bad sensors. Maybe the pi you are using gets very hot compared to a pi zero and this leads to sensor failures? It would be good to determine the reason, if the sensors are really broken, and if they are damaged forever, what the cause is?
You said it worked with the old openplotter 1.2?? this doesn't make sensor for the sensors but maybe the hardware serial port wasn't configured in op2 and this is why the controller didn't work?
