Jerry, you made me think about things again, and I was confusing Mass Air Flow control which uses a hot wire flow measurement with Speed Density control which simply looks at TPS and MAP, using MAP to control mixture. As you said, with Speed Density you can have many throttle bodies with the TPS for a load reference.
Mike,
glad you found the 2x4 reference at FAST. Makes sense that you can make it work and it should look super cool mounted. Keep us posted on your progress. That self learn feature from FAST and others is pretty sweet - saves lots of head scratching.
