this is the message i get when i try to update the board with it all together

[NEMO]

update ive reupdated the Arduino back down to 202103 from 202202 and everything works i dont understand why the update is doing this

[NEMO]

i believe i found the issue update 202202 seems to be causing a communications issue but update 202108 works %100
EDIT: tunerstudio still fails to detect the ecu with the boards connected on 202202 but if a new project is made with just the arduino connected with the 202202 update it works and if the the boards are reconnected it will auto connect but if done manually in the communications setting it cant be found and testing the port always fails

Don't bother with latest update.

The comms have been problematic.

Stick with the older firmware for now.
