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

Will you recoup money spent on mods in fuel saved? see my spreadsheets here
