Did you ever figure out how to wire it up? I have a supercharged 94 Cobra that came with the megasquirt pnp2 already in it and I just installed an AEM Failsafe Wideband gauge and I’m trying to figure out how to connect it to the megasquirt
Ok, tell me about wideband o2 sensors with relation to the MS3. From looking at wiring schematic, it appears I only need one O2 sensor, and for datalogging it should be a wideband.
Install one wideband, cap the other bung (or leave the stock o2 sensor in) and then connect the signal wire from the wideband to the MS and that's it?
This would be a better question to ask in the digital tuning forum, let's get you moved over there and I can answer any questions you have in regards to tuning and wiring.Did you ever figure out how to wire it up?

Well first I need to know exactly what you want to do, I already moved your post for you.
I assume you just need to wire the wb into the ms2pnp yes?
Ok you will need to disconnect the factory O2 sensors if they are still installed. The input for the O2 is in parallel with the factory narrowband units.
Take WHITE to pin 21 and BROWN to pin 22
thats a very expensive setup to just use it as a WB. I would have told you to purchase a spartan2 from 14point7.com since the MS2 already does everything else that the unit you purchased does...
BTW the AEM stuff has a tendency to burn up the sensors, so keep one on hand.
Nope, you get one wb input on the ms2pnp. Not sure for the failsafe, I assume it only has one sensor? If so then if you want to read each bank you would have to move it. If it has 2 sensors then it likely outputs a signal that is an average of both banks.
You will need to go into the tools menu in tunerstudio and calibrate the input.
You will need to purchase the plug with pins from diyautotune to install.
