Following up on this. Setting P07 to 1 works well. Thanks again, you've been a big help!

Thanks again, vfr. That makes sense. The previous owner had some extra lights attached, which could have overloaded the transistor.

Here's another one. The bike I just bought (used) has a headlight, but it's always on. the only way to turn it off is to cut the wire, which is exactly what the previous owner did. In fact, holding the up button on the SW900 to turning it off only makes it brighter! Any suggestions?

vfr: thank you. That may be just what I'm looking for. P07: I've read that for a direct drive motor it should be set to 47. I'll try that later today, and then maybe try 1 to see what works best. P13: I counted the magnets and I have 5, so I can use that setting. P17: I'll try 100 and see how that goes. Thanks for the explanation of what it adjusts. the user manuals on these things are anemic at best. Interesting point on the test. Thanks again for the help.

dumb newbie move here, but I was poking around in the SW900 that came with my ebike, and I think I changed too many settings, and now it's not functioning properly. The setting I need help with are P07 (Magnets quantity to measure speed: 1-100), P13 (Power assistance magnet quantity setting: 5, 8, 12), and P17 (Power choice function: 100-200). How do I find out the correct values for these settings? I have a Cyrusher XF700, 250W motor: QH4GV 36V*250 W Brushless Hub Motor
