Just an update - this is still ongoing.
Ridetech in the USA seem to be really willing to help - which is good.
The engineer on my side has also been good, but he seems a little...busy. So things are dragging on a bit.
Can't blame the engineer for having a bit on, probably a fair indication he is in demand and good at what he does. He also seems very competent and knowledgeable and does appear to be real deal, BUT so far it's been up to me to nudge things along. A little frustrating.
Early days yet I suppose, but I am a little concerned about losing momentum and Ridetech's interest.
Hopefully I will have more to add next week..... : (
