00 S2000 Wideband using A30 ELD pin

[dimitry8]

So I have an AEM wideband I want to connect to my Kpro ECU ELD A30 pin (green/red stripe wire) for dataloging. Do I tap and share the ELD wire or do I cut it off and solder it exclusively to get input from the wideband sensor? Thanks.

You must cut it, as it can no longer be connected to its original location.

Thanks! got it working, but the datalog shows different numbers from my gauge. seems to be off by 1-1.5 AF could it be the way it's grounded? It's on a common ground on the chassis and It gets power from the fusebox under the panel. I got Kpro4. I got the conversion tables filled according to the AEM values.

Have you adjusted the offset voltage until it matches?

[dimitry8]

I did, but it seems like I have to adjust it every time I start the car to a different value it varies between -0.5V and -0.8V so far. ELD has to be disabled right?

[Spunkster]

If it is different every time, then it sounds like there may be a problem with the ground you are using. It should be the same every time.

[dimitry8]

I've changed the ground from a common ground to it's own individual chasis ground, to taping into the PG2 ECU Power Ground and it's doing the same thing. I start up the car and the kmanager, adjust the voltage offset until it matches my gauge, but as soon as I turn off the car or if I close kmanager and open it again is off sync. What am I doing wrong?

What is the serial number of your K-Pro board inside the ECU?

[dimitry8]

44218

This is a version 4 K-Pro, you should use the analog input on the K-Pro board for the wideband and you will then be able to run closed loop from the wideband as well.
