M800 pin B14 0V (comms) to use with LSU4.9 0V possible?

[MikeD]

Hi,
on the M800 are those 0V ref pins B14, B15 and B16 all tied to the same potential or is there some different circuitry internally which denies the use of B14 for engine sensor purpose?

Actually I'm in need for another 0V sensor GND and my options are to either splice into the existing wire on pin B16 0V engine sensor), but as I don't use B14 (0V comms) this would be more convenient in my situation.

I will use the Sensor GND in question for wiring the LUS4.9 Pin 2 (0V) with M800 internal LA1 option, and of course the motec lambda datsheet #57006 suggests to use B16 (0V engine sensor). So I will do in case that's the only way to do it correctly, but if B14 is equally fine then that's my preferred choice.

Thanks

Hi Mike,

You can use the 0V pins like this.
