I installed my new Mini Maxx today. Unplugged EGR and powered programmer up. Everything looks great except. Mini Maxx will not download to the truck. Called H & S and they told me to check SD Card which I did. I also downloaded most up to date download to SD card and tried to reinstall. H & S closed for the evening. Any help on what could be the problem? Also, error on Mini Maxx stated "COULD NOT OPEN ? CODE"

 

Any news?

 

yes he got it fixed. h&s fixed it for him.

 

old thread but make sure when you get a new download put on the mini max or blackmax make sure to go to update vehicle or software before you go to install download thats what gets most people

 

his trouble was from dealership changing out his pcm and didnt do it right. jason sent it to h&s and they got it fixed for him.
