FW: FW: Electromotive FI

[Atkinson, David]

Fred, I have what you would probably consider a low-revving, "stifled"   
V8.  It's a 454 bored .020" over, mild cam, single plane intake and the   
TEC-II.  It runs like the dickens and furiously propels my 4WD '57 1-Ton   
Chevy PU to warp speed.  Now this is not a race motor by any means but   
it's the strongest one I've ever put together and the TEC-II handles it   
just fine.

Of course simply setting IOT and TOG on a high-revving, 'non-stifled'   
engine may not cut it but some tweaking is always necessary.  The TEC   
system can handle non-linearities by adjusting the values in the V.E.   
(Volumetric Efficiency) tables, so I don't see how this could be an   
issue.

I'm curious - in which applications have you found the TEC-II system to   
be inadequate, and why?

Sure will!
As long as your engine is thermodynamically linear. Like a low reving,
stifled V8.
Forget it on anything much more interesting than that.
