Wideband controller for monitoring D15Z1 lean burn
I have a D15Z1 and am using the L1H1 sensor and P07 ECU.
Since there are a bunch of wideband controllers out there that use the L1H1 sensor, I'd like to hook one up so I can use the gauge for monitoring AFR.
I just want to make sure tapping into the needed wires for the wideband controller wont screw with the readings that the ECU receives.
Also, are there any wideband controllers & gauges that can read leaner than 20:1?
