Hi mates, I just replaced my OEM stock O2 sensor and installed the AEM UEGO one. So I spliced the 0-5v wthie cable in the D14 pin of the ecu to use the UEGO as my stcok sensor. I have the ecu chipped and the O2 hetar disabled, but today I get the next cell codes:

1, 2, 20 y 45

1 and 2 Is related to the O2 sensor but I dnt know why.
the 20 (ELD) I guess it is because the imput voltage is now 0-5v and the ecu only admit up to 0-3.7v
and 45 is related with fuel too much rich or lean, but my UEGO gauge is showing between 15-17, and +18 on idle.

Is there any othe splice, trick or whatelse that I forgot to do whe replaced the 02 sensor??

Thanks.

Well , I just used the simulated narrowband from UEGO, but in narrowband mode the readings from the UEGO gauge are leaner than the wideband mode. And in freelog Im unable to get the same values as in the gauge, neither with default mode, or slope 2, 10.
