this guy used the NISMO manifold to run ITBs with a KA24E-T setup:

but for some reason his "fuel system" page is blank now. the last time i looked at it was a couple years ago, so i don't remember what he used.

when i got into bmw e30s, MegaSquirt was real popular. what a lot of guys did was leave the stock Motronic ECU in to run ignition, and then used MS, which is MAP-based, to get rid of the AFM. i think that's probably how i would go about it...

you *could* just enclose the ITB inlets in a plenum and have that pull through the hotwire-MAF, but given that ITBs are pretty much pointless if you're not running a hot cam, i think you're going to want some kind of programmable engine management (at least fuel, if not both fuel and ignition) to make the effort worthwhile.

YEA THATS ACTUALLY WHAT IM SAVING UP FOR RIGHT NOW(HARD TIMES) TO PUT ON A CAM. SO YOUR SAYING TO A CAM, GET THE MEGASQUIRT SYSTEM WICH ALLOWS THE ECU TO BE TUNED BY THE ENGINE MANAGMENT SYSTEM RIGHT?? OR ARE YOU SAYING JUST TO DO ALL THAT WITH OUT THE MAGAS SQUIRT!(HA!HA! SORRY NOT THAT PERFOMANCE SMART)!!!
