Default AEM wideband sensor install without gauge

Hello guys,

I have bought the AEM wideband sensor and wish to install it without using the gauge.







There are 5 wires :
- red
- yellow
- grey
- black
- white

Does anyone know the colours’ correpondence ?

Thanks

Really? It was easier to do the search then to post the question.

EDIT: WTF, it's Sunday... Search term: Genuine Bosch LSU4.2 Wideband Sensor wiring

You can't just connect the wideband sensor directly to engine management. These sensors must be used with wideband controllers so you can have a usabe voltage output. (unless your engine management has a built in wideband controller, not only input)

Thanks for this info ! I have a Reverant built MS3. It does have a wideband input but I don't know if it's able to read the output voltage directly from the sensor.

They all have wideband input.

No, you still need to use the gauge. The MS3 (and currently no Megasquirt) can control the sensor directly.

Its not like a narrow band. Its output is a change in current, not an analog voltage or a digital signal. The sensor needs a controller in order to sense the current and convert it to an analog or digital output.

In other words, if for some reason you dont want a gauge, you can just get an LC-1 and use that sensor. If you want a gauge get an MTX-L and use that sensor.
Its the same sensor, you dont have to use the AEM, and you should not use the AEM unless you happen to already have it.

The connector is unfortunately is proprietary to AEM, so there's very little incentive in trying to match it to an LC-1.

You can however, use the AEM Inline UEGO, AEM Part Number 30-2310.

The connector is almost identical. You can use a normal Bosch sensor with the AEM you just have to cut a little plastic tab off the connector with a razor blade.
You should be able to use the AEM sensor with an LC-1/MTX-L with no modification.

I can say with a high degree of confidence, that they are in fact, very different.

You can use a bosh sensor with an AEM gauge, you cant use an AEM sensor with a Innovate/bosh gauge connector.

Pic in OP is of a AEM branded sensor so it will only plug into a AEM gauge. He can however replace the sensor with a generic bosh one later on if he chooses.

You can't swap connectors on non-Innovate sensors/gauges, as they also contain the precision-etched calibration resistor that matches the sensor.

No problem doing so on an Innovate gauge, as they don't use the calibration resistor at all. Ie free-air calibration anyone?

Right, you can not cut the plug off the sensor or it ruins it. The connector on the end of the AEM gauge (not the sensor) is smaller than the one for a Innovate style and will fit inside the connector of the larger innovate connector on an innovate sensor allowing you to replace the sensor without going through AEM.

So to clarify, with no modification necessary, You can use a bosh/innovate sensor on a AEM gauge/controller but not a sensor with a AEM connector on a bosh/innovate controller.

Thanks for your replies. I wanted my car to be as close as possible to the OEM appearance. So I didn't want to install any gauge. I'll have to revise my thoughts

Hide the gauge in the glovebox or throw it in behind the radio.

Or use the AEM inline uego like I said, which doesn't have a gauge.

I don't like the idea of installing something that I won't use even if it's hidden

Nice (but expensive) way to go

Buy this
LC-2 Wideband O2 Digital Air/fuel Ratio Controller

If you cant afford that then maybe you should leave your car stock.

But you will be using it. You have to have it. Even if you don't look at the gauge its self, it is needed to read the sensor.

Or just get what Full_tilt posted.
