Rayfredo,
Welcome to the forum, I hope some one will be able to help you with your specific issue.
Almost exclusively the language used on this forum is English, and I'm sure that you will get a far better response were you to re-post your request translated into English.
Mean while, would you like to post something in the Introductions section telling us a little about you ?
Google Translate helps a lot:
"Hello
I am new to the forum, and I need help
I have a controller RMHV2.1 but the programmed advance always remains at 50mm whatever the value
I changed the firmware with pandora, but nothing changes, I still have the problem
can you help me solve this problem
a big thank you in advance
cordially, rayfredo "
