Me again,
just in case anyone is interested the reviews on the 2005 Dyno46 software were not too flattering, lots of bugs, gremlins and not so reliable. There is a bloke in Malaysia that supplies upgrades but that sounds complicated.
A lot has changed in the software game since 2005 and I have narrowed the search to two companies that seem to know their stuff, one is US at approx $1,000. the other is Australia at approx $1,500. I,ll see which the dyno owner wants to go and give you some feed back just in case anyone wants to build or update one.
ciao
