single bank fueling on e38?
ok so my question goes
if one were to modify the injector bank select (under engine/fuel/general) so all the cylinders are on bank1 (which is 0 in injector bank select)
and then remove the bank 2 o2's, and put the bank 1 o2 sensor after an exhaust merge (before or after the turbo) or better yet use the wideband that is already after the turbo to simulate a narrowband signal .......
would said person have closed loop fueling control on all cylinders via bank 1 / bank 1 o2 sensor?

I’m curious to find out the correct answer to this as I run an o38 single turbo and a single 02and one bank runs hotter on the pipes than other

ive never used only 1. always 2.
ive always put them in the dump pipe. I have found with several cars the turbulence in the dump causes on sensor to have +STFT and the other -STFT. this is only at idle and light throttle. as soon as some gas flows they come good. I generally just do them in full open loop SD
