Pressure sensor ground. LOGIC or SENSOR?

[TurboTommy]

1.In the the Smanager instructions for adding additional pressure sensors, it says to use logic ground, I wanted to make sure this is correct as I thought logic ground is used to ground shielded cables and sensor ground is used for sensors.

2.Can I use the ground on the s300 Analog section and use 5v ref from a tps ? Thanks

You must use the ECU logic grounds
"Be careful! The logic ground pins A26 & B2 are next to +12V pins, which will damage the S300 / sensor if connected by mistake."

No you should not use the grounds on the s300.

Thanks! But is there any particular reason why its logic and not sensor ground? Just trying to understand, thanks!

Logic ground is a volt ground.
