wideband off in higher RPMS?

I'm running a H22a4 with a P28 hondata ECU with a M series PLX wideband.

I notice that in the higher RPM's my gauge will read 12.6-12.8 but it gets datalogged at 13.1

but in the lower RPMs everything matches up fine?

the wideband is ground at the ECU jumper harness and I have the capitors from PLX installed as stated in the instrutions.

I have the wideband set up to the ELD D10 pin, with the wire cut, and am using the stock narrowband for closed loop

Where are you getting power?

I would recommend using the switched 12V source at the under dash fusebox, and for the ground use a good solid chassis ground.

everything is wired at the jumper harness like it said it should be at the PLX instructions.

We do not recommend getting power or ground from the ecu harness. Please follow the intructions on our website.

Switched the ground to a chassis ground near the OBD2 port, adjusted the table as suggested by PLX. Everything matches up fine in all RPMs now.

Thanks spunkster for the quick accurate response =)
