P and C setting for Carrera Crossfire E with custom Controller (SR Suntour hub motor)

[lumisoft]

Good day. So finally managed to hook up custom controller to my Carrera Crossfire E bike. I can't seem to gert the P and C settings correct. It seems to work in certain level but I throttle too hard or too often it cuts out - like the BMS seem to cut out - have to re-seat the battery and it works - but with same issue when throttling too hard or too often. So seems like my P1 might be wrong - it's on 87 now - suggested by other forum but I can't find specs for this 250W SR Suntour HESC motor. Any one might have fiddled around Carrera bikes? Vengance seems to come with same motor and original controller - so suppose it's specs would be similar - I suppose most Carrera's come with same SR Suntour setup. P and C suggestions would be greatly appreciated.

this is my current setup:
P1 - 87, P2 - 6, P3 - 0 - P4 - 0, P5 - 15
C1 - 06, C2 - 0, C3 - 8, C4 - 0, C5 - 2, C6 - 3, C7 - 0, C8 - 1, C9 - 0, C10 - n, C11 - 0, C12 - 4, C13 - 0, C14 - 2

I can't help with your issue but you might be able to help with mine. I have a broken Carrere Subway E with suntour HESC hub and components. Something is broken - I haven't yet figured out what. Assuming the motor is okay, I imagine I will want to replace the suntour contoller with something more generic, which is what you did right? Did you have to replace the display too? Were you able to retain the original batteries despite handshaking?
