Default DIYPNP - Cannot calibrate TPS

Ok so I wired everything together, DIYPNP is properly recognized by the computer.

I plugged the unit into my 93 n/a car. First tried to calibrate things and the TPS was not reading correctly. It's all stock, I changed nothing in the tps.
TPS is grounded with a resistor per the directions on the diypnp board. The TPS does not respond when I press the accelerator and the numbers are all over. Also its buzzing, and the values keep rising no matter what I do and theres no way to make it come back down unless you restart the car.

Do you know what the issue might be?

Thanks!

Your inbox is full.

You can't calibrate a stock TPS, because its not actually a TPS, its an on/off switch. You need to swap it for a real TPS.
