So as of right now I have just about everything I need to install my PFC on my S4 TII. one question remains though...

I plan on using 720cc and 1600cc low impedance injectors. Will I need to use resistors with low impedance?

and also, i only have a base map for the factory 550 injectors... how hard is it to interchange the injector size in the settings?

 

you need a datalogit.
Thanks Robert

 

already have. i would have listed the things i need if i don't have them. Injectors are the real question

 

hey willub adjusting injector size is pretty straight forward. just use the correction formula. only thing youll need is to find your injector dead time or injector latency as apxei likes to call it. if u need help drop me a PM i install and tune PFC's pretty often.

 

To answer your question.... yes, you will need injector resistors....

Search for what to do there, as the topic has been covered to death

 

10 volt 10 watts from radio shack

 

well, would say, it depends on injector loads, would go for 25W resistor to be sure....

if you have an 87 S4 you do not need resistors because they have a resistor pack stock. Only the 88s need to have resistors wired in.

and I have had best luck with 6 ohm 10 watt resistors. the stock resistor pack on an 87 is 5-7 ohms. i found that i had hesitations with 10 ohm resistors.

then again, a lot of people run them with no problems.

 

I asked Banzai and they told me to use the 10 watt 10 ohm. I have an 88.
