EFILive WideBand Logging Question Does anyone know the sampling rate of the extra data inputs? I was wondering if they are limited to the car's output rate or if they are independant.

They can be logged independantly.
Depending on how fast your PC can process the data....the sample rate goes to well over 100 samples per second of the three values. (600 data items per second).
Testing on an 800MHz pentium laptop give about 130 samples per second.
The three values are:
1. Temperature from the cold junction compensated K-type thermocouple input.
2. A/D input 1 (may also be also used for WO2)
3. A/D input 2 (may also be also used for a second WO2)
Probably won't do much good for some wide band O2 cotrollers as they only update their output signal at a slower rate than that.

Great Thanks,
Some of the other products really have slow logging of the extra inputs. I am looking for around 100 Samples/sec for what I am doing.

Probably want to contact the wideband manufacturer to see what kinda output it provides, as Paul mentioned, the wideband controller may be your slow point (I'm not sure of the outputs of any of the wideband units though)
