System Too Rich Bank 1
Hey guys,
I have R53 with RMW cam, 17% pully, RMW injectors, Alta CAI, and RMW Tune.
and I keep getting System Too Rick Bank 1 code.
There are no leaks anywhere (I hope), and I have tried the adaptation with the INPA software, and and tried with the BMW original software and etc....
Before I replace the O2 Sensors, is there any other areas that I should check?
maybe the RMW injectors are spraying too much fuel??
or maybe the tune???
or maybe the cam???

With your mods a wideband O2 gauge is highly recommended, without it you're just pulling straws.
Is the code for the Pre or Post cat O2 sensor? What header do you have?
