does anyone know the jcw's injectors' duty cycle on jcw cars or pulley-ed cars(15% etc)?

 

Isn't that determined by the ECU tune?

 

i meant for stock ecu map

 

Call Jan of Rmw or Jason of mynes they may be able to tell you.
They are the only two tuners i know of that may have acess to that info.

 

i think it varies from car to car, and also the type of mods you have. If you have the right tools, you can view the parameters while the car is running. Since you're in Socal, you might want to give RMW or Mynes a call?

Jaytech posted this time ago as to why they recommend the 550cc... just focus on the jist of the argument and bypass the silly stuff
