KT 1KW controller, odd behaviours w cruise, regen ?

[marka-ee]

I am using a 1000 watt 36/48V KT type controller, and have some odd things going on. The LCD programming has the cruise feature turned off, but when I keep the throttle on for a while, it going into a cruise mode by it's self ( backing off throttle it keeps going ignoring the input until I move it around a lot to reset it ). Caught me by surprise and I don't know if this is a fault of a feature. Again, the LCD programming has cruise set to off.
The other odd thing is sometimes I sense a regen type activity where I feel the motor doing a braking function. Brake wires are unconnected/unused. I was thinking that maybe the hal sensor signals could be causing this but usually in the past if I had a hal sensor wire issue the controller would error out and need a reboot . I have blown two of these 1000 watt KT's before, running on a DCDC boost converter and now suspect that it may have been an unexpected regen that may have caused an overvolt condition for the DCDC and then blew out the controller. I'm using the DCDC boost because I have a bunch of 10S packs that I got at a good price a while back, but I want to be able to go faster . I ran the 500 watt KT for a couple of years with the boost and never had an issue until the Boost converter suffered a bad Vout trimpot which caused it to make 100 volts ! Blew fets and all three 63 volt caps up. Messy fluid inside but after a wash the low voltage electronics and cpu survived, somehow.
Anyhow, I want to get my higher voltage speed back, but I'm afraid of using the DCDC boost on the 1000 watt controller so now I'm going on 10S alone, limp mode.

Regarding the un-commanded cruise engagement, I've seen that as well, but my cruise is set to on. If yours is set to off and you're still getting it, seems like there are a couple of short leads coming from the controller that must be connected together to allow the cruise. Maybe revisit your wiring diagram to see if you have those? If so, maybe try unplugging them?

No issues regarding the regen. but I'm running a little more conventional setup.

Thanks. I'll check the wires, and tape the unused brake and cruise ones to make sure . Right now I'm running it totally conventional as in no boost as I'm afraid of blowing this spare controller as well.

What does the display show when the "cruise" is engaged". If the controller is in cruise mode, then you'd see a big "C" on the display, as I recall (didn't use cruise much on my old KT controller). If you don't see that on the display, then it's probably something with your throttle or connections.
