David,
Sounds a bit like overkill to me but, hey, it worked. It's all percentages I guess so how ever you determine the error is fine.
I am, BTW, STILL waiting for the ratio adapter I sent to The Speedometer Shop. They don't have a working email but do have a phone recorder. If they ever listen to the messages is still a mystery sometimes. The first shop, that did it backwards, didn't ever return calls or have email either.
I did manage to talk to a guy yesterday at the Speedo Shop in SoCal. One of them is going in for cancer surgery today. Good luck to him..I hope he does well. The other guy is, I guess, trying to run the place by himself. My probs seem pretty insignificant in comparison...
