Ok, so dwh4784 got one of these AEM widebands. here's a link to it. http://www.aemelectronics.com/wideba...fuel-gauge-25/
The instruction manual here: http://www.schnitzracing.com/manuals/AEMWBK.pdf
talks a bit about the different selector settings on the back of the gauge.
My question is, do these different settings output through the signal wire? or does it just change the reading on the gauge face or both?
Right now it is set at P0, if it's set to P4 will it output that signal on the signal wire without changing the actual AFR reading on the gauge face?
I'd like to wire it up to the ECU and ditch the stock O2 all together if possible.
