A different perspective of Ned. Interesting ...

Understood. I would also be interested in that- does he have the "design"
knowledge in "mapping", or is he (simply) good at verifying/comparing
(via analytical/seat-of-pants testing) a *given* setting/map? Either way,
results are results- there is some value in his final, composed product.

Maybe not a simple divide- could be a curve (function). I'd heard of
transducers (the meters and motors) that were either modified and/or a
box sat between it and the computer. If the EPROM also has the
signal-conditioning constants for its inputs and or outputs, then that's
possible. Otherwise, there would be other hardware included in the IA mod
kit, like an electronic analogy to the stiffer/nonlinear wastegate spring.
