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?

bump for great questions that need answers.

I'm going to bump this again because I've been wondering this myself lately and cant seem to find and information on the subject...

From my understanding no one has risked their $150 oxygen sensor to tap for a wideband gauge. Please feel free to be the first and let us know how,it works for youl lol

re: I just want to make sure tapping into the needed wires for the wideband controller wont screw with the readings that the ECU receives.

When my VX was in the shop recently being worked on by a former Honda mechanic and civic modder, I asked him that question specifically and he said it would not interfere.
He is currently into playing with 16:1 lean burn on an older turbo Mitsubishi Mirage HB.
I will tap into mine whenever I can afford an appropriate monitor gauge.

For those of us not up to speed on Honda engine management, why do you need the controller? If the wide band sensor is already being used as such there will already be a controller in there somewhere.

You just need to tap into the signal with a volt meter. The meter or the circuit, i.e. voltage divider, it is connected to should have a high impedance or resistance to avoid altering the signal you are reading but that's all.
