Come on guys, you can do better than that! :)

Test with 1.5v battery did not help much. As I was getting voltage from wideband analog output anyway... Just made sure ELD input voltage is not changing in sManager sensor window and so isn't the O2 (d14) pin

According to your statement "If you don't get close to 1.5V then the ECU doesn't support the ELD input", euro P30 ECU doesn't support narrowband O2 either which is impossible and we all can agree to this.

d10 input is not working and d14 input is not working (as I already described it in post #1)

R136 and R138 are pull up/down resistors, and need to be removed. Can you clarify why the 1.5V applied to D10 did not work? What voltage did you see when datalogging?

There is always constant value of voltage when datalogging (for ELD and O2). ELD ~1,78v (removed r136 and r138 resistors) and O2 all the time is ~3,79v.

Voltage isn't changing at all, no matter if applied voltage to d10 and d14 or not.

You need to try a different ECU as it sounds like this one either does not have the circuitry or has been damaged.

Back to report. We connected another chipped ecu and tested input with Crome. It was the same problem. Then we discovered ELD input responds when moving ecu connector. Plugged back my ecu with Hondata and ELD responded when I applied quite some pressure on connectors. I haven't had a time to check which pins should be repinned and don't have continuity, but apparently it's not ELD pin as I checked it before!
