Any suggestions that don't require buying a new Wideband?

 

I also have the Zeitronix, did you have to do anything in the XML files in ECUflash/Evoscan?

 

No, you use the Zeitronix software to set up the NB switchpoint you want to use then replace the stock o2 sensor signal with the simulated signal from the ZT.

 

Thanks for clearing that up for me, I appreciate it man

 

Doesnt MrFreds patch allow this? Wire up WBO output to rear o2, and then his patch simulates narrow band output to the ecu from the wideband and you disconnect the front O2 and can now log whatever you want off the narrow band input pin.

Unfortunately, according to the AEM website UEGO has no simulated NBO2 output. If you don't like going for another WBO2 with all the options, I can only suggest two ways:

1) MrFred's patch if it is available for your car - preferred choice
2) going full-time open loop, when your car's ECU simply doesn't care about the O2 sensor - inferior choice

Also you may consider selling the UEGO and buying Zt-3 or whatever WBO2 that supports NBO2 simulation. This way the costs associated would be minimal.

 

I think the best thing would be to just add the narrow band. Does anyone know why the oem mitsu O2 sensor is soo expensive? Is it the same as another 4wire narrowband O2?

 

You don't have to buy it direct from Mitsu, when mine packed up I bought one from another site for ~80$ IIRC.
