Staring at my FD before winter...

[DriFD3S]

I noticed a few things, while admiring it's beauty, and superiority over piston engines,
I saw that my ABS unit, has a lot of wiring...
Is there any way that the factory ABS can be modified to be used as a front/rear brake pressure controller?
like, in any way can I modify or change the way my brakes work, AT ALL?
or, am I just stupid?..

Also, to the best of my knowledge, the RX-7 I own has 550 primary, 850 secondary injectors...
To all you guys who have a Power FC, or have tuned or modified a MAP...

I wanted to know, a few things...
fuel injectors should only be used to 70% to 80% max duty cycle,
(IE: 550, is really only 440, right?)
But, do the primary and secondary injectors put gas in the engine both at the same time?
Or does one max out, then the second one begins?
I really don't know, but, what I was thinking,
wouldn't it be a good idea, to figure out how to make both fuel injectors work at the same time, both injecting fuel, in a way that was constantly using both to the maximum of their potential?
like, if 1120(CCM?) is the maximum a stock FD can squeeze into the engine,
what is the MINIMUM that will be injected??
if anyone knows, can you please share your experience with me?

Thank you!
