Questions about imu

Hello, i’m wondering if i can use my autosteer without the imu, because i have seen a lot of differnt opinions and i don’t know what to say. I have preety flat fields, with small slopes.
I tried the autosteer on flat ground and it went all good, and now i want to know what will be the maximum limit for autosteer without an imu.
i already bought an CMPS14, but i have a hard time making it run.
any advice will be good for me.

Try it and see if it’s good enough for your situation. If not, you can always add imu later.
