Hey guys,
For the ease of deflation using APEX valves, i know there are specific after market TPMS that provides an external tiny device/monitor to read the tire pressures. I want to keep my stock TPMS, but have something that reads the tire pressures. After some digging,
there isn’t a simple “external dash screen” that wirelessly reads the OEM TPMS sensors directly over RF all the time, but rather they require their own
valve-cap sensors.
The practical approach i found was to use an OBD reader that is capable to read live TPMS data and has an iphone app that i can see the readings when deflating. Not sure if you guys have done something similar.
My questions are:
- Which OBD tool you recommend that can provide live TPMS data and has a phone application. I have the BlueDriver OBD, but TPMS data, however, lives in proprietary GM networks (Body Control Module / Tire Pressure Module) and uses manufacturer-specific PIDs that BlueDriver doesn’t read or broadcast in real time.
- Do you recommend an OBD extension to use 2 ports as i have the power steps connected and want to connect an OBD reader too.
- Can i install secondary TPMS sensors in addition to the stock oness.
Sorry for the long message and appreciate your support
