What firmware are you running?

Have you actually loaded the 508 firmware?

I had a problem with my HW Xtreme Stock switching to sensorless mode, no sign of 'cogging', but it was very slow. Turned out to be my cells. The voltage protection was cutting in on high loads. I disabled the protection and the speedo has been fine since.

'Cogging' normally means too much advance.
