I tried the latest version of the JPDiag (release 28) with a license file of the old Ducatidiag and it seems to work. I have not had the opportunity to try on a bike, but the tour seems to work since functions are "trimmer" and "reset the TPS".
I saw that with the new version of the JP Diag ? been implemented with the function for the tension of the belts, that was installed with the sw "Courries".
