I got 91T USDM with AP Engineering Apexi Power FC installed. To install this AP Eng. PFC into 91-92T properly, you will need:
-Rewire some of ECU harness wires
-Rewire/install Intake Air Temperature or IAT sensor (It's the one that attached to the engine lid).
-Buy a Gen3 Manifold Air Temperature or MAT sensor and install it in the intake manifold where the cold-start injector is (Replace cold-start injector with MAT sensor).
-And optional Gen3 Manifold Absolute Pressure or MAP sensor if you want to boost beyond ___ psi. <-- Fill in the blank...I'm not too sure how much the stock MAP sensor from Gen2 USDM can take up to.
(Thanks for-mrlaws, rhouck, flapstar, and other board members for sharing these info)
Yes, you can get ridded of AFM with this setup without any problem.
(I'm selling my FC-Datalogit...click under my siggy) <-- lol
oppse not sure what i was thinking jdm ill slap myself for typing that lol if you get a sec go to www.vtrides.com im not sure what page im on but i have the only mr2 on the site 1-4 in vt that i know of. lmk what you think.
Oh... You were trying to say JDM. I went that site and saw your car already, your car looks nice and clean man and I love this part the most:
new ashtray (lol) <--haha
Back to PFC, I am not sure that if the regular (gen3) PFC will work on your car. But the AP Engineering Apexi Power FC is designed and should be pluged and played for your JDM Gen2 3S-GTE motor (-no ECU harness rewire needed-) and if you want to get ridded of AFM use those sensors I mentioned above and you'll be fine. Normally PFC has a base map to start up the car and runable to dyno.
Email me if you really want to get more information on how to install those sensors.
