S300 v3 and Aem uego

[Alistair206]

Hi hopefully I’ve posted this in the right section

So I’ve finally installed my s300v3 p28 I’ve had my wideband running for a few months and it’s been reading correctly but as soon as I swapped from my stock p28 into the Hondata p28 the readings on the gauge itself have gone well out of spec

I later pinned it’s white 0-5 volt wire into d14 and on the live data it’s showing a afr of 18 but the gauge itself is reading 11, if I return the stock ecu back into the car it returns a reading of 15 on the gauge, I’ve tapped the power and the earth for the wideband off the ecu’s power and earth for reference

I’ve spend about 4 hours looking for answers but not found much of any use so I was wondering if anyone else has had a similar issue?

What AEM wideband?

Need to know where you've placed the power and ground wires as well as probably posting the calibration since some of the settings are likely not right.
