IAC. Check the frequency setting.

Ahh ok thanks guys! It's not going to hurt anything buzzing like that is it? I was concerned something was wrong so I shut the car down right after recording the clip

Not right away, no. If you don't use the correct frequency setting it will kill the valve.

FWIW, mine was noisy in my basemap from Rev @ 313hz, bumped to 480hz (per 500hz suggestion in linked thread above... it's as high as I can go) and is a low hum now.

Ok next dumb question... Did I do something wrong? Are wires backwards on my TPS? I have a pnp TPS sensor from the guy on here who sells them all the time, so I doubt he wired it wrong

Ok so also I ended up bumping the Inc frequency to 503hz.much quieter now... Hopefully that's not too high of a setting.

Off work tomorrow and can't wait to VE analyze and drive around and see what it does!

Don't VE analyze anything until everything is calibrated properly.

Right. You either wired it wrong or calibrated it wrong.

I'll see if I can either flip the connector or maybe I misunderstood brains instructions

On the dashboard screen of TS, TPS should read 0 with your foot off the gas. Press the pedal and watch it change.
If it's not reading 0 when closed, and doesn't go positive numbers when you hit the pedal, something is wrong.

Ok so the plug is not backwards... Its either incorrect wiring or I improperly did the procedure. I'm pretty sure I followed brains instructions exactly though

did you actually install a vTPS?

the buzzing is actually a bit bothersome, since the freq you should be using is whatever was loaded (something like 100Hz).

Yes I have a TPS from railz on the forum. Here is how he has it wired...
