What new fuel injectors?
I am wanting to replace the secondary injectors on my 8, probably will get new ones from Mazsport.
The Mazsport page has "High or Low Impedance Choices 650cc, 780cc, 880cc, or 1000cc"
Why would they have two impeadences for the RX8 fuel injectors?
What does the standard factory RX8 secondary flow?
I assume the ECU will not let the injectors go full output, but will I need to remap during the install? (Do I need to have this done AT the tuners shop?)

I've been searching, but I can't seem to find anything about the injectors really.
there are three sets, right? 1 for each port, which port set is primary, then "P2"?, and then secondary? When do all of these "activate" , can this setting be changed?

a good bit of injector information.
You really have to use firefox to view this forum, open up the parent forum "Tech & Performance" open all of its child forums in a new tab and read through every sticky in the child forums. You'll be able to tell the ones that you don't have to read too.

i've read all the stickies, the only thing I'm still a confused about is the calcLoad thing . what is that?
I understand fuel maps, but how do they change with different TPS values? or is it more complex than that?

You have to tune for it regardless.
Also, I'm pretty sure the PCM figures fuel flow by pwm settings for the injectors, it doesn't have a flow meter or anything. So if your injectors are larger then things aren't going to match up.

The O2 sensor would just say "Rich mixture" and the ECU would go lean it till the proper AF ratio was reached; soon the ECU would re-learn what is rich and lean.
Not gonna happen?
