Finally solved my DSP error problem and it was a very easy fix.
Just I did not saw that before that in motor signal wire socket one of the female pins were bad.
And then male pin inside female pin was moving and there was contact and not contact depending of the movement.
But to get to the cause I resoldered just in case male part of that socket and event opened motor encoder area to see are there everything ok.
And I tested with tester wires between motor and socket and between sevcon and socket and these were good. And only then I bothered to look at the socket itself :wink:

replaced this bad pin and now everything works like new.
Here is picture of that bad pin :twisted:

I got my motor from this thread, but that was a year ago :)

Tested Zero air-through cooling this weekend in a race that was very acceleration and braking intensive and motor was not able to cool itself enough by pumping air through by itself.
Theoretically inner rotor should act as tesla turbine and I actually felt the air through motor very well when wheels in air and rotating in 5000rpm.
So it seems I need to install active air cooling, two powerful centrifugal vents to pump air trough at faster speed that motor itself can do :)
Video of first race when I hit the wall, because I lost rear brakes also due overheating :(
