3uzfe wideband with G4+ xtreme


Recommended Posts

Hi all

I have a 3uzfe running with a G4+ xtreme. I was originally going to run narrowband lambda and maf (factory setup) just for reliable n/a power until i supercharge later on down the line. I'm going to be taking my car to my tuner in the next month or so and figured i may aswell convert to wideband for easier and better tuning for them. Is it just a case of getting 2 bosch LSU 4.9 wideband sensors, one for each bank. I already have my narrowbands wired up so should just be plug and play with wideband sensors i guess? And are those bosch sensors the ones to go for? Any recommendations?

 

Also, i'm running maf at the moment, would converting to map be a better option for n/a tuning, would it be more accurate? I need to go map in the future for charging, so again, may aswell do it now

Thanks

The wideband sensors will require and external controller to provide a suitable signal to the ECU. We do a CAN Lambda unit for this or you can also use the like of a LC2 or equivalent with a 0-5V out put which can be feed to the same pins as the narrow band were.

I would suggest MAP based tuning for almost all applications where there is a good MAP signal we are not really geared to MAF tunes.
