Paul,

Refering to the P-Port thread, I was reading the Mazda paper you recently
posted on the Le-Mans 4 rotor and it seems they had the same problem,
which they corrected by putting the fuel injectors as close to the engine
ports as possible. fwiw  Perhaps you could take another look at that
paper,particulary the last three or four paragrafs.

Thanks :

 I think Mazda did that for throttle response reasons. A race driver needs power
right now. Mazda probably used a throttle position sensor, RPM and maybe the
intake manifold pressure as well to calculate the fuel needed. Tracy's system
does not use a TPS but the Meagsquirt does.

I think we have another problem and that is the intake pressure at
a particular time, in the intake manifold, is changing with RPM. I suspect
Tracy is briefly measuring the pressure, in the intake manifold, when another
chamber face is 22 degrees BTDC. IMHO we need to either average the pressure
somehow or use a mass airflow sensor that averages the amount of air going in
the engine.
