is it possible to create different earth points for the wideband sensor and analogue in when using the VEMS AFR EGT gauge?
Not really, or rather No.
What is making you want to do this?
I was told by someone that it would be a good idea to have the wideband sensor grounded to the engine and the rest to another ground. It doesn't matter matter i've just used the single ground and everything seems fine
Hi,
Grounding one device in two different places is a very good way to damage it! :o
That's why you don't :)
Cheers,
Gavin :)
