What Throttle Position Sensor (TPS) to use on DIY ITB's? I just finished testing my GSXR to F22B2 OBD2 TPS setup and everything works fine.
Here is how I did it:
I am using the stock GSXR Secondary TPS as it already has three wires ready to go. The primary GSXR TPS does not, it has a male connector on it,
Secondary TPS on the left, Primary TPS on the right.
I took an old Civic TPS and cut the guts out of it and exposed the connectors on the inside. I then cut the rest of the old TPS housing off. Leaving me with my newly created male connector. After soldering the three wires in there proper positions Sig/Gnd/Ref I had my GSXR to Honda TPS conversion ready for testing....
Close-up of the altered Civic TPS hooked into my OBD2 wiring harness.
New TPS and harness connected for testing, I used a screw driver to turn the GSXR TPS to simulate WOT.
I ran all of the standard Honda Voltmeter tests to confirm that the TPS was working correctly. At this time I was also able to record the actual voltage range for my new TPS so I can add them into my ITB TPS settings in Crome. I don't have any actual images of the readings as I only have two hands and I was flying solo today. Here are the readings that I read: 1.13v @ CT and 4.89v @ WOT.
With the most current tuning software that is available. It is very easy to calibrate non Honda TPS voltage values to enable smooth operation.
NOTE:
If you use the primary GSXR TPS the voltages are pretty much spot on with the Honda specs. 0.46 @ CT and 4.47 @ WOT
