I have a KT-LCD3 that came bundled with a Risun 18 FET sine wave controller. I have both working great now, but I'm trying to fine tune the cadence based PAS system. Here's what I found that is odd:
The instructions that came with the LCD3 are the same as the many manuals that you can find online, and the videos people post on YouTube. But, the available options for at least two of the setting is different on the actual unit. For the maximum speed setting, everything I've seen online shows the max as 72, but on my unit the max is 99.
For the PAS sensor setting, C1, I've found that the only value that detects the PAS sensor is C1=04, which isn't defined in most of the manuals (most define 0-4, based on the magnet configuration). I had forgotten this about C1 when I first set up the controller, and had decided to sort it out later, so when I added more magnets to my disc this weekend, and set C1=02 for a 10 magnet sensor, no PAS.
With C1=4 and 10 magnets, the cadence the controller thinks it sees is too fast, so on level 1, I'm barely providing any pedal effort even in my top gear (which is low, 40:13, since I'm only running one chainring up front). If I can't figure out how to change the setting, I'll likely remove two of the new magnets so that I'm contributing more at the lower settings. My thought is to remove the ones that the sensor would see just before my power stroke on the pedals, since I like how fast PAS comes on from a standing start with the additional magnets. I only have them hot glued in for now so I can fine tune.
Anyone out there own a KT-LCD3 with the same odd settings above? I'm hoping that one of the other settings affects which setting work for C1, but haven't figured that out yet.
