Hi Everyone,
In the final stages of putting on a single turbo so I've got a couple of questions regarding configuration for boost and O2 Sensors.
In regards to boost, I've done an E40 ECM in the past which required a custom operating system to be applied with HPTuners to suit a boosted application. Is this still required with the E38? I have fitted a 2.5 Bar MAP Sensor as well.
With the oxygen sensors, my vehicle originally came with 2 O2 Sensors pre and post cat for each bank but now I'm running a single exhaust system. Do I still run an O2 sensor before and after the cat and if so, how do you disable/tune for running one bank only?
Sorry if this has been covered but I'm having trouble finding anything relevant with searches.
