Hey i've been playing with my new scan tool and have noticed WOT is only 92% open all the way to floor. Any ideas how to adjust?

Have you watched the scan tube in the upper speeds. You maybe limited only in the lower range......

Previous years would limit the throttle body up to 40 mph before opening all the way.

The 4X4's in the early years seemed to come in sooner at about 17 mph I think it was.

So I assume the newer models are the same...and I assume the scan tool can read the ECU correctly.

I assume it too be true and there is nothing you can do until UpRev cracks the new ECU like they did on the earlier models.

Good point..It may be limited. I was running this test at engine off. I was running the Idle Air Volume Learning procedure when i notice to WOT percent.

I'll run it down the road and test again..

Scan tool or Scan gauge. I have the scan gauge and it only show 77% at WOT.

That's how it's read. Does not mean it's not wide open. Some cars/trucks read 100 at WOT while some read even lower.

You are reading with Cipher right?
Even before UpRev you were getting 100% WOT except only after 40mph.
