I can't help you here, much. I have the Pfaff and the Inspira but I have QBOT and the stitch regulator isn't needed. However, I do suggest you contact your dealer and ask if it will work on your machine/frame. Good luck!
On edit!!!! My DH just informed me I DO have a stitch regulator (for the times I don't use the Qbot) -- DUUUUH. yeah, bought the set-up second hand...and I'm NOT mechanically minded. We looked and the # on mine has velcro over it!!! sorry!
