Great to see, that you are continuously improving the JB4!

Just installed the update and here is my quick feedback:

1) Reading codes via the JB4 app is no longer working. It just says "Read failed"
2) disabling the startup sweep works
3) New firmware runs less smooth for me, with the same settings that were good on v8. A lot of throttle closures below 3500 rpms in Map1 and Map2 and boost is lower than in previous firmware version.
4) Attached some logs (v8 and v9) with the same setting that worked fine in v8 and also the default settings

5) went back to old firmware for now
