It is unlikely that the firmware would remain the same over time. C15 parameter has been added, who knows what else. If it has never been tested for this sort of behaviour it is doubtful they are even aware of it. It is relatively easy to program something to do what you want. The hard part is...

Yes, must be my lying eyes or hubris maybe.

After three runs with a different controller and with all other components the same there has been no replication of the fault. I'm calling this as a software issue with the KT controllers.

Moved it to 2500 which is a cadence of 16. Probably gone too far. Only one way to find out.

Assuming I've got the maths right. Previous setting of Ramp end was 1000, 12 pulses per rotation, so a cadence of 40rpm before full power from selected assist level applied. Now adjusted to 1500 so 27rpm. Will see what difference it makes later. Edit: Feels better, I'm going to keep increasing...

Fixed the assist indication on the display. Now works and blinks when the pedals are rotated. Finally starting to understand the PAS settings. Borrowed this diagram from the German forum. Ramp end and PAS timeout are timed amounts between 2 PAS pulses. This is in recorded in 8000ths of a...

Rather boringly it disables the watt meter until a series of actions have been carried out. It then remains on until the power is switched off. On startup the meter is disabled again. There would be nothing to stop it being coded to activate a speed limit bypass or some sort of smoke cannon...

I've had another look at this and the setting only appears to do something with a torque sensor. I don't have one so it can't have caused the issues from yesterday. As the battery was getting low it might have been my untested 36V code kicking in.Charged up the battery today so won't have to...

Changed the PAS Impulses per turn to 12 from 32. Absolute pants. Changed it back. Will investigate further later what this setting actually does. The display bars are well out from where I've set them. Adjusted the calibration factor and now look more realistic. Walk assist from the display...

There are plenty of other things to sort out. I get the feeling the the KT displays have not been widely used with this firmware, so trying to get everything to display as it should. Also changing settings to see if I can improve the ride. When it gets there in a couple of weeks I'm happy to...

28mph on the downhill, pedalling through the V and on the up hill and...works as expected. As soon as you drop below the set point power resumes. One swallow does not make a summer though. I shall keep monitoring.

I now have a fairly good idea which parameters from the Kunteng display actually do anything. The assist level is transmitted to the controller and changes the level. The maximum speed is transmitted and changes the parameter in the modified Lishui controller. C3, C6, C7, C8, C9, C10, C11 are...

Good question. I have my 28mph downhill followed by a steep uphill on Monday. It will be a good test. This will be the first time that I have had an accurate speed reading while attempting it. Last time I did the hill I had disconnected the white speed wire so had no display and no cut off, so...

Previously I'd set the wheel circumference by measuring from the floor to the centre of the hub, multiplying it by 2 and then by Pi. As a back up I ran the wheel one revolution on and then measured how far it had travelled. Both were within 5 mm So should be accurate. Sellotaped my phone to the...

The legal settings are the same. 6kmph without pedalling. Pushing the throttle while pedalling gives a graduated output though. Push it all the way and you get max power, less that and you get proportionally less power.

That's not how it felt. Maybe the torque simulation is more nuanced, who knows? Well maybe someone on the German forum but that would mean reading through 150 pages translated by Google. I will give it a week of riding. I'll look out for the behaviour that you mentioned and report back. It does...

As it stands these are my initial feelings on the Lishui controller compared to the KT. Positives - Graduated legal throttle rather than an on off switch -Ability to increase the power on the start assist. On the old controller it always felt a bit weedy. Strangely on my other bike it felt...

I have experimented moving P1 up and down but it makes no difference. It could be it's not mapped from the display to the controller. I will have to try amending the value in the code to see what happens.

Thought the Amazon link I posted earlier was pretty near. 5mm out. I could be wrong though. If someone else wants to confirm. https://www.amazon.co.uk/TANGZHIMI-Bracket-Bicycle-Central-Crankset/dp/B09YTMVWP3
