I just put these injectors in for secondaries and am getting ready to set up the Power FC. Question comes because as I look at the specs at 40psi these are actually rated at 690cc, 715 at 43psi, and 730 at 45psi. Should I still put in 725 for Q value or should I use the 690 value?

 

match the Q value to whatever it is rated at for your fuel pressure. You can always raise it if you want to. Then put the lag values directly into the lag vs. battery voltage table.

Basically just set up everything according to the specs. See this thread: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/fjo-injector-driver-installation-895398/page2/

 

Got this one figured out. Just found the manual specific to the FD, much better than the universal manual I found through Apexi.
