hello we jsut got a hpc 500 motor controller that we want to use for a project was wondering how I can do that. I cant find the programmer on the webstore but I found the application I think. where can I in the eu buy a programmer? this link was shown on the site but gone https://goldenmotor.bike/products/hpc-controller-usb-programming-interface

Hello Mike!  Thanks for the response.  I've given up on the idea of a pot based throttle and am going with a hall based throttle.  Most of the reason is on the hall from Domino, it has a microswitch which is closed when the throttle is in the off position.  This switch is to be wired to the low brake connector on the controller.  My understanding is that's how you enable regen on the VEC500 controller.  I ran some brief tests, and closing that circuit stops power to the motor, and the wheel stops rather quickly.  (it's on a motorcycle on a lift with the rear wheel off the ground.  The only issue remaining is the controller beeps when the circuit is closed.  Is there a way to turn off beeping on regen?  Please don't tell me I'm going to sound like a delivery truck in reverse every time I ease off the throttle.

Thanks!!

The previous link should now be working properly, and that post explains what could happen without the throttle voltage range protection being enabled.

If you have a potentiometer type throttle, raising the protection voltage to allow its maximum signal voltage (~5V) would basically have the same effect as disabling the throttle voltage range protection.
So you could still end up with the motor stuck on full throttle if any of the connections or wires on the ground circuit of the throttle failed due to fatigue or suffered physical damage etc.! 

If temporarily disabling the throttle voltage range protection cures the cutting out at full throttle, you should add some resistors and re-enable the throttle voltage range protection for safety reasons.

Apologies for the delayed reply but I missed the notifications for your previous replies as I'm still experiencing major grief with all of my Hotmail email accounts on my Windows PC and on my Android phone.

I'll try to check the controller settings tomorrow... but isn't there an "automatic" setup for these controllers?

There is no automatic setup for these controllers, just the ability to load the factory default settings, which may not be correct for your setup.

Tried my hand with the program... tried to up the boost, the maximum drawn current etc. but the bike now will go into protection as long as the throttle is twisted fast.  :'(

Any advice about how to make it better from dead stop without making it "stall" into protection mode?

Could the fault be happening when the throttle is being twisted fully, rather than just being twisted fast?
I'm wondering whether you may be experiencing a problem caused by the throttle signal voltage exceeding the Throttle maximum allowed voltage (V) value at full throttle, but this would usually be accompanied by the 12 beep/flash error code from the controller if this were the case. 

If your throttle is a potentiometer type (not a Hall Sensor type) it could be triggering the Throttle voltage range protection if the throttle signal voltage output exceeds 4.0V at full throttle with the default throttle voltage protection values.

If you are not sure on the throttle type, try temporarily setting the Throttle voltage range protection enable value to 2:Disable and see if it cures the problem.

Check out this post for further information on the Throttle voltage range protection values and why it should be enabled.

EDIT: Faulty link repaired

My setup shouldn't be much different but I have veeeeery different results
