What the thread found

• The Arm X-1 uses four interchangeable spring canisters with individual tension adjustment and an additional ISO response setting per spring, providing eight tuning options total.
• Increasing ISO response settings makes the arm feel stickier, while decreasing ISO makes it feel less sticky similar to older 3A style arms.
• An upgrade in May 2019 introduced new spring designs and materials (blue and black) that improved arm performance and increased load capability compared to older silver and gold springs.
• The new springs were available as a universal modification for all arms manufactured since 2010.
• Users can adjust boom range by rearranging arm components.
• The upgraded springs produced noticeably improved responsiveness compared to the previous generation.

Depends on

• The original poster's arm was assembled before the May 2019 upgrade and contained the older spring generation.
• Tutorials for fine-tuning the Xtune system were mentioned as in development but not yet available at the time of discussion.
• No detailed technical explanation was provided for why ISO adjustment affects stickiness.
