Just got a chance to road-test the new code and it's not working...
I tried vss/mile values of 98302 and 166770 and both reverted back to lower numbers in the 16 bit range - with significant over-reading of speed as a result.
We are quite close - the MPGuino now seems to read speed consistently. With the value maxed at 65535 I get approximately 30% overread on the MPGuno compared with the speedo. E.g:
Speedo > MPGuino
20mph > 31mph
30mph > 44mph
40mph > 58mph
