tim... need to ask you about the itb setup..
do u still use the map sensor or are u only using throttle possition sensor?
i'm seriousely interested in going itb .. but i have a limitted budget so i can;t afford a standalone ecu.. which is great when it comes to tuning using tps.
my plan is to use the itb's from toyota's 4age modded to b16a inletmani. i'm planning to install a plenum to increase driability.. and tap 4 vacuum source from each t/b and use a fuel rail as a manifold for a map sensor..
do u think tuning this setup will be a pain in the ARS>...
