GTS TCU flash for M2 Competition ( EU spec )

Hi Guys!

We tried to flash the GTS TCU software to my M2 competition ( Eu spec with OPF ) but unfortunately it has some compatibility problem, and after some minutes the gear level indicator dissapears from the dash ( even in Manual mode ) and right after the paddles / shifters do not respond anymore. It may be kind of a limp mode, and it only works in automatic shift.

We tried to flash the GTS software via ESYS platform. ( Not bootmod3 )

Today a friend of mine had exactly the same problem on a new M4 competition ( also new EU spec with OPF ). That's strange because we thought the problem in my case could be the newer digital dash of the m2c, but the new M4 has the "old" normal dash, the same like old M4's... So it seems like it will be a different problem... Maybe the OPF ???

Is there any new software data request from the gearbox with this newer OPF cars ?

Has anybody ever made a GTS TCU flash which works on new eu specs M2 Competition ?

I had this issue and had to re-flash to stock tune. I asked on a FB group and was told BM3 wasn't really compatible.
