Bought a new TPS because the old one appeared to be "dropping out" intermittently on a 20 frame per second log. It would go from some open % TPs down to zero and back up again, every few seconds. Installed the new one and it does the same. Logged RAW TPS V to see if the signal to the ECM was...

How many pulses per driveshaft rev do I need to enter?

I know part of my current battle with idle control is this "big" cam, coupled with ported heads, and 120# inj with E85. I am working my way to getting the throttle blades open enough and conversely the IAC counts low enough (10-20) for a controllable and decent idle, but it got late and gave up...
