I was going to bring some in, but this controller is some what strange to calibrate. You can try a Schulze: fut-18.46K, fut-18.61K, fut-24.40K, fut-32.28K, fut-32.40K. I have a fut-32.40K and when I have some spare time, I will try to create a freak of a mini for some speed runs. Forgot to add the Kontronik Jazz line up: Jazz 40-10-24 and Jazz 40-10-32
