What are your afr calibration points for aem 30-4100 wb
I calibrated my 30-4100 at 0v=10:1 4.99v=19.95:1 my calibration is close to a whole point of in ts compared to the wideband. I pulled the power from the radio in the Miata. Maybe I can tinker with it until they get close to matching up. Anybody want to share voltage and calibration points.

Yea, I tapped into my megasquirt powersource just a little while ago and i'm still one point off. I guess i'm going to have to tune based off what megasquirt is seeing, i'm just adding a point in my mind, so when it shows 13.8 afr on the gauge its actually like 14.4 on the computer. Guess i'm just going to have to live with it.

Hi Jason,
Try moving your ground around. This is pretty common - Take your ground location for the gauge and ground it to the "analog sensor" ground on your ECU if you have one. If not just use the same ground location as your ECU.
If you do it while the car is sitting at idle you'll literally see it change to the correct number. I see this all the time.

Yea essentially I'm trying to understand where the ecu (megasquirt) is ground off to its the factory harness. I'm spliced into the power and ground using the little vampire clips I really need to pull the seat again so I can get enough wire to solder the power and ground in instead of the clips. Wonder if that is giving enough resistance to throw it off.
