Hello everyone,
I have been looking into a wideband for optimal tuning so which would be best fitting for my application? I have a Gen4 LC9 E38 and I want to install a permanent wideband gauge. I've been looking at different AEM models. I plan on hardwiring the gauge so before I buy the wrong WB, which one should I go with? I do not want to piggyback all sorts of adapters and I would prefer tapping into the back of my OBD port (if possible) for any TX/RX signals for data logging into the MPVi2. Does anyone have a pinout or instructions for this?
