pfc injector settings and sard Fuel Pressure Regulator?
 

should I modify the pfc injector settings with a sard Fuel Pressure Regulator ?


I am running the stock injectors 550cc and 850cc and a supra fuel pump.


thanks

I think it is depend on the target and actual A/F ratio.

If you can manage AFR with only changing the Base map, the pfc injector setting is not needed.

thanks for the infos!

How many rwhp can I safely achieve with the stock injectors , supra fuel pump and sard / tomei fuel regulator?

Injector settings are based on the injectors lag vs voltage, and the flow rates for the base fuel pressure that you will be using.

If an injector flows 725 at 40 psi and 40 will be your base fuel pressure, then use 725 as the injector size.

If the same injector flows 770 at 50 psi and 50 will be your base fuel pressure, then use 770 as the injector size.

You all need to do some studying on this crap!

got it
thanks
