just out of curiousity is the mpfi system on 88-91 crx/civics batch file (fires all four injectors at the same time) or sequential (fires one injector at a time right when the intake valves open)?

 

Just from personal experience on my obd0 b16 in my 91 crx si...when I was checking the fuel system, it did shoot all 4 at once. I don't know if it would be any difference...my car isnt converted to MPFI 'cuz that's how it comes.

 

thanks for the quick response Does anybody else have any input?

 

they fire seperatly.

 

anybody else because i have gotten one answer saying batch file and one saying they fire seperately, so which is it?
