Just use one MAF sensor and double the fueling in the ECU program. Ought to be pretty damn close. No reason not to use a single TPS either as long as you have the time and software, etc. to get the tune right.
i think i might have figured out a way to do it, wouldnt be perfect but i think it would still work, i believe if we just used like a a.f.c and changed the in out settings enough to make up for the second throttle boddy. i think it would work. thats what alot of other nissan guys do when they run different mafs. since its a hot wire maf, unless your engine flows enough it will give a false reading to ecu. like when 240 guys put z, and q45 mafs on the car, the ka does not cool the wire down to where it should be, so it makes the car run lean. so in theory we could, like i said change the in out settings on it so that it thinks its seeing more air, than it actually is. not perfect but im sure it will work. after that we can go through and do as much fine tunning as possible on one.
