Randall,
As for your interpretation of optimal Fuel Mixture:
Mine was in " " marks meaning I copied and pasted it from a page or
someone elses quote.
Here's the Webpage I copied and pasted from:
http://www.hondata.com/techlambda.html
I'm sure you gathered your information from another source. Usually TR3
Owners don't have to crunch such numbers.
I hope your time was well spent, You may very well be right or have stumbled
across better information.
I understand your confusion over the A/F accuracy as the wide band example
didn't go through. That and having read several of your
previous posts after lengthy nose in the Thesaurus sessions
Here's the Wide Band Unit Link done cheap for most.

for the Throttle positioning sensor being used in an alternativeapplication,
Don't let anyone catch You using Pliers on a Thumbscrew.But: This News Just
In!Wikipedia Throttle Definition:A throttle is the mechanism by which the flow
of a fluid is managed byconstriction or obstruction. An engine's power can be
increased or decreasedby the restriction of inlet gases (i.e., by the use of a
throttle), butusually decreased. The term throttle has come to refer,
informally andincorrectly, to any mechanism by which the power or speed of an
engine isregulated.So since the most restriction in Airflow by constriction or
obstruction isthe Piston in an SU under Full Throttle,So It is technically the
Throttle. Ididn't say Butterfly or Disc position Sensor.As for You and 100+
mph. Sorry I don't know You well but can only havevisuals that would advise You
to double up on whatever size Depends Youmight use:^
)Like You say, Your Goals may be more" Lofty" But Your Mileage may Vary,
Ibet.Cheers,Wayne64 TR475 TR6Hawke DL12 Formula FordLola T598 Sportsracer (goes
