I want to get a wideband 02 sensor and see the readings on a windows tablet mounted in the dash through aem tuner just a few things.

im running AEM EMS v2 can i just buy a sensor and tap into the existing 02 ( i know aem v2 dosent use the standard 02 sensor) ?

do i need a controller box for the sensor ( is that just for a gauge set up ) ?

which sensor for the AEM EMS v2 ---- Bosch 4.2 or 4.9

Thanks

Hi im installing an AEM Wideband O2 sensor into my car with an AEM EMS V2 ECU. Do I follow the pinout instructions and connect the Wideband O2 to PIN 19 & PIN 29 or could I rewire it into the wiring for the OEM O2 sensor and delete the narrowband O2 Sensor

AEM_NS: Either way gets the job done.
Either way gets the job done except that you wouldn't replace sensor ground but instead tap it.

 

Cheers David and thanks for the link to the sensors.

still need a bit more info which sensor to go for 4.2 or 4.9 or will both of them work with the EMS

 

I asked them about that with the 4-channel wideband controller. They said no, it was 4.2 only. I had really wanted to run NTK 24300 (formerly called L2H2). But the AEM 4-port is the only came in town with back pressure compensation anywhere near the pricepoint.

You can ask explicitly on the AEM forum, but since it is the same vintage as the 4-channel controller, my guess is 4.2 only.

Note: I looking at it for a 2JZ-GTE, not an S2000.
