Anther Fuel Question
Can I get to much fuel and my Airfuel mixture guage shows no indication like it just drops all lights mean that the O2 sensor is over whelm with too much fuel?
And how will I know if there is not enoughor enough fuel on boost?
I am using 550 pri and 1600 sec with a very reliable fuel regulator (cartech).

Well I tested the car today, getting closer.
When I get on the boost and the car start to pull hard I back off and when I look in my rear veiw mirror i see a cloud of light blue smoke and heavy smell of un burnt fuel (almost cought the car on fire one large fire ball sometimes) When I try to lessen the fuel the car will just cough and would not feel right. Is my 1600 sec to big for my engine? or should I install an after market fuel pump

yeh you gotta get a wideband O2 on it. Tuning by 'feel' is very very risky on our beloved rotaries or any turbo car for that matter. The 'narrow-band' a/f ratio indicators (autometer et. al.) aren't adequate for any real tuning. The car should really be taken to a dyno where it can be tuned properly.
What ecu are you using? A 550/1600 setup can be difficult to get right where the secondaries come online, you may find that there is so much fuel in there that its snuffing out the spark. Check your plugs are nice and clean. Your standard fuel pump might be running out of juice, the 1600's are very large injectors. To check this mount a fuel pressure guage (available from any hydrualics shop for ~$20) on to your fuel pressure regulator via a bit of hose so you can see it in the cabin (be careful!) check that the fuel pressure increases with boost and doesn't drop off at all under load.

When I boost at stand still the pressure will increase to about 55-70 psi with 12psi on the boost gauge
And when I am driving the car goes on like a thoo thoo train either not enough fuel or flooding the engine after getting off the boost lots of smoke and strong smell of fuel almost got my car buper on fire just burnt a little after a large fire ball.
Maybe I can check my spark plugs they might be foul and not taking the fuel properly.
