Procede Rev 3 + Meth Datalogs - Difference in AFR b/w banks

[froop]

Hi,

I was wondering if anyone would be able to review my datalogs and let me know what could possibly be the cause for the significant difference in AFRs in my datalogs.

The first 2 were taken yesterday on the dyno (Got 316.5kW atrw on a dyno dynamics roller. Stock run was 185kW) and the other was taken during a drag run. The car appears to run fine other than a couple pops and burbles when cold starting. I have pulled some lambda codes but have never had any misfires or anything.

Someone told me it could be to do with the lambda adaptations so I reset all of the adaptations before this latest dyno run and it appears to be the same if not even worse. I've even tried some injector cleaning stuff in the tank.

Looking through my datalog history it seems that this car has always done this. Before people say that it could be the meth when looking at the live values on the procede user tuning interface, even at idle bank sits 2about a 1 point lower than bank 1.

Am I up for O2 sensor or injector replacement?

Thanks,

Alex
