Hi, I upgraded to mes 1.7 and I can't perform uniair dispersion setting, do you think I have to downgrade again to mes 1.3?

You mean that it worked fine in v1.3 and now it doesn't work?

Exactly, in mes 1.3 I could do a "short dispersion correction" as it didn't last 15 minutes as told but just a couple of minutes. Nevertheless it activated all the solenoids, it kept the engine working at different rpm, you could hear it was "doing something" and, last but not least, there was no yellow engine lamp activated and no p1320 error reported. One hour ago I succeded in obtaining a new licence key to register downgraded mes (to 1.3) but, surprise, the new key doesn't work on older versions... I'm so disappointed...
