Wide band readout

Post by 98GTI »

So before i went standalone i bought all glowshift gauges including a wideband that uses a bosch sensor. Now that im integrating it with my ms3 pro the numbers on my gauge and the numbers on the ms3 pro dashboard are different off by about .3 afr which is pretty large. but im not sure what one to believe!! the Ms3 reads richer than my gauge so atleast it error into the rich side which makes me feel a bit better.

They sent me a file with the readout and I graphed them to make sure the numbers were linear and they are darn close, the forum wouldnt let a word doc to be uploaded but i changed it to a pdf so you could see

What do you guys think i should do?

Sounds like a slight ground offset. Is the wideband ground and ecu ground at the same location? Plus it could be a simple error factor, all electronics have a % tolerance, so this could be that too. I'd trust the gauge, and once the grounds are confirmed, you can setup a custom linear just outside the given specs to get it to match

Does the gauge have a sensor ground input?
