Paul,
   I know you and others are working on alternatives to feed the P Port
   slide throttle. Tracy's ECU works on MAP and because of the pulsations
   and short intake this will not work. Mazda stock ECU has TPS could this
   work with a re-programed or adjustable ECU offered by these folks?

   Well the jury is still out. Mark Suspinski p-port engine seems to be
   working
   fine on the ground with Tracy ECU.

   I think these are stock units that are upgraded.
   Perry Mick has a stock unit working fine. He had to trick a few
   sensor inputs as I recall. Last I heard he was still working on the
   leaning circuit.

   It uses a stock mass air flow sensor that looks like this.

   I am looking for somebody that is close to flying to test my mechanical
   EFI.

I was going to use the stock ECU from Mazda, UNTIL  I learned that the
units are programmed to SHUT OFF ALL POWER TO THE SPARK  if your engine
'overheats'
(that event's temperature seems to be undefined).  I chose Tracy's unit
for my turbo powered Long-Ez.                          John

There must be away around that as Perry's engine has overheated several
times.
