R32 / R33 / 34G Force Sesnor, What Data Is Available On It?

[Chris Wilson]

I am talking about the sensor under the glove box on the transmission tunnel, is there any data on it? Is it 2 axis? How many G does it read up to? What does it output and what voltage input does it have? Anything like that would be nice! Thanks.

[Duncan]

Would love any data on this too.

My g sensor is wired into my data logger, and any calibration data would be helpful

I don't have any perfect voltage VS nissan g force data but I do know the nissan g sensors voltage VS my motec actual g sensor data logging.

So motec G force VS Nissan sensor voltage.

It should be fairly accurate I'd think but I don't know the exact g force/voltage the Nissan sensor uses.

Duncan it's all written in a log book from my old GTR that's at the workshop next time your down there.

[Duncan]

so you have nissan volts to motec volts, and motec volts to actual G? should be easy to map out, I'll remember to bug you about it

[Chris Wilson]

Standard 0 to 5 volt output, but I have not found a G force V voltage output curve yet.

[Risking]

That's exactly what I have Duncan.

But I don't have motec volts only motec G's

I can look in the motec configuration and find out the voltage/g force figures.

I think it was just a linear ratio from memory.

I was logging the oem sensor both laterally and longitudinally, the motec also did it's own lat & long data logging which is reported in G force not voltage.

Back in the olden days when we wanted to check the calibration of a gee sensor we would tip the thing on its side. By doing so you imitate 1 gee lateral (or longitudinal). 30 degrees = 0.5, 45 = 0.71, 60 = 0.86 gees. If it is linear you could comfortably extrapolate from that up to 5V.
