TPM Re-calibration

[PRG]

Can I re-calibrate the TPM values using the 911?  If so, what shall I use as a base reference?  A good hand held gage?

No, the GS911 cannot recalibrate the TPM sensor.

The only way I have found to recalibrate them is to deflate the tyre completely, leave it deflated overnight, and then wake the TPM up with a wake-up tool.  TMP will then register "0".  Then inflate the tyre to the desired pressure and the TPM should display accordingly.
