SAME REASON PEOPLE ARE NOT STILL USING A 386 computer...
the chips are not fast enough..
batch fires all 8 at the same time.. so the caculations are 8 times less than senquential
bank fires in sets of(in the v8 case) sets of 4
and the caculations are 6 times less than senquential..
senquential fires the injectors and times the engine as 8 single cyl engines..
it takes 8 times the speed and power the ecu that controls my tbi on my fiero does.. or any batch system ..
ya I could run windows xp on my old 133 computer if I wanted to start booting it up a day before I use it.. but the power and speeds not there..
I plan on a dual stage nos system.. I can't have it somewhat close. it has to be spot on.. a little lean and toast..
efi is a computer.. cpu speed and power is EVERYTHING.
