BulletFactory Posted December 3, 2017 Report Share Posted December 3, 2017 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 Quote Link to comment Share on other sites More sharing options...
Simon Posted December 4, 2017 Report Share Posted December 4, 2017 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.
