Re: Advice/Suggestions on Ur-Q Chip Upgrade

["John Corbishley" <gtr1@traverse.com>]

That's the interesting thing.  Ned himself suggested it, so I have to
believe that he had BTDT and found it to work.  He was also suggesting
getting the complete harness with the ECU.

If you are out there Ned, please correct me if I am misquoting you.  Please
all also note that the discussion at the time related  to my '83 Ur-Q.
