Theres also people who have made stupid HP with Nos and no aftermarket ECU and ran it for awhile with no issues. Doesnt mean it's smart or effective. Just means your lucky =).

 

he's just busting my chops

well dude you have everything you need to see if your car is fine. The wideband will tell you about fuel supply. But wait you are no longer using the Fcon...


I don't understand that statement- what was the car tuned with then? From what you are saying you can't run the F-CON since it's for newer version FD.

 

I have the power fc commander and where i must look (monitor,injector duty cycle)???

 

o.k i know that but what is the correct numper for 470hp e.g 70%

 

thanks man.

 

Is the PFC tuned to this setup? If it is then it's easy to check injector size. Just check the settings.

If the PFC isn't tuned (How could it be tuned without knowing the injector size?) . Then you better not go around flooring it to see your injector duty cycle because you will blow it.


To see if your injectors are inadequate:
On a TUNED car (with the Power FC set to the injectors that are installed) all you do is go WOT and monitor your duty cycle. Anything above 85% tells you that you should be using bigger ones. All logic suggests that your car isn't tuned so DO NOT TRY THIS. In my opinion take them out and have a specialist inpect the damn things, as others have said they are probably boared 850's to 1300's.

 

The '99 parts car in question had a "hks f-con programmed by Feed in Japan"

In his good '92 chassis he will be using his Power FC with the '99 parts cars drivetrain.

 

If you ran like 60 psi base pressure the stock injectors could make the power (flywheel HP) at 100% duty. You would need one hell of a fuel pump, or 2 to keep up with the flow at those kinds of pressures. It makes more sense that its 1300's bored out

 

thanks for your help,here in Greece we are 30 years back at knowledge in rotarys.

 

Oh don't say that I'm in Istanbul and about to buy the last clean FD in the country, I was relying on Greek Rotary mechanics for anything major like rebuilds etc. I was planning on driving to Greece because here we have ZERO rotary specialists/shops here and Mazda doesn't carry parts FD & 13b
