e30 speedo compatibility -- question?

[brian_vancouver]

My understanding, is that there are at least 3 versions of the speedo used in the e30: miles/hr; km and miles/hr; and km only. My question is whether the sensor mounted on the differential is compatible with all three, or if a different sensor is needed, especially between the "miles and km/hour" and the "km/hr" speedo? My current speedo is "km/hr" alone and I want to know if a "miles/hr and km/hr" speedo will work with my current sensor?

Thanks for any help on this,

Brian

same part. but more importantly, same "speed" no matter what so it wouldn't matter. It's just a conversion on the gauge face itself.

E30s have a digital speedometer. The calibration of the gage is unaffected by the gear ratios. The only thing that does affect it is different tire sizes - but as far as I'm aware, stock E30 tires are about 23.9" OD so the calibration is basically the same on all of them.

and yeah, the kmh/mph gages are just different faces on the same gage.
