Welcome to the forum! I moved your post to the CrossFire XR category as you’ll get more focused attention. AND you should be aware, as an XR buyer, you have a direct service access number with Langmuir. Look under MainSite->Help->Support->CrossFire XR
I contacted support using email at the bottom of the page.
They responded very fast, first asking the year of asset (3-12-21) and then stating -
"This machine will not need an upgrade.
If the software is showing you have a misfire then it’s most likely a software issue and contact Langmuir. Most likely it will be a THC Cable or the module box.
Make sure you are running the machine on a direct 220-wall plug and no extension cords. The PSI on the machine with the trigger pulled or firing should be reading 75psi on the gauge."
