I'm wondering if I can connect the simulated narrowband output from my TechEdge to both HEGO monitor wires on the A9P. I would then tie the wideband output to the EGR monitor so that I could datalog the wideband. I'm using a quarterhorse.
I wouldn't try tying a single simulated narrowband output to both HEGO inputs, the fuelling is not usually the same on both banks. What's wrong with using narrowbands?
I don't have any narrow band sensors or a HEGO harness. The long tube headers only have a bung on one bank. It is a lot more time and money to hook up both narrow bands. If I turn off the narrow band using TunerPro does the ECU go into limp mode or will it run just fine?
