The first throttle, which would be an OBDII (with the integrated TPS) would handle all the closed loop, low rpm acceleration, and most of the daily driving duty. Then, somehow, rig up the second throttle (this time an OBDI throttle so I don't have to worry about TPS input) to open as a second stage for more air to feed the motor.
The thing is, I want to keep the primary OBDII throttle intact with the velocity bumps so it runs perfectly smooth. Im experimenting with a completely honed out throttle valve right now, and while the WOT power is really nice, idle quality sucks. I was thinking if I could keep the primary for 80% driving duty, then cable up the secondary to open at a certain throttle plate position and just open up.
But my main problem is how the engine sees the load.....which lead me to my original question:
How to wire up two MAFs.Several thoughts. First, the TPS usually only indicates a closed throttle (TPS less than 2%) so that the ECU can know when to manipulate the IAC motor and thereby control idle speed. So it is possible that the TPS may not be totally responsible for your erratic idle condition.
Idle fueling is traditionally controlled by a mass air or speed density calculation. Which causes me to wonder- if your ECU will support speed density fuel mapping (MAP vs. RPM) why not use a MAP sensor and forget about the MAF altogether. With a high performance-likely high overlap cam, your MAF signals may be confusing to your ECU anyway.
