Hey Guys. Please advice on HOW to hook up AEM Wideband sensor to the AEM EMS (model 30-1313) NOTE not U.

I just purchased it and cannot find a way to where hook up the wideband wires. It just says to install the sensor inplace of O2sensor on the dump pipe.

Please advice.

This product is legal in California for racing vehicles only
into vehicles already fit ggers. It furnishes the
user with real time, accu m consists of the AEM
UEGO controller with wiring harness and one or two Bosch wide range sensors with weld in
sensor bungs. The controller is available as both a single or dual channel system with one UEGO
sensor per channel.
Each O2 channel features two different analog outputs, a 0-5 volt signal and a 0-1 volt signal.
The 0-1 volt is a “Lean to Rich” calibration specifically designed to simulate the output range of
a narrow band type sensor. This can be fed into a stock ECU to keep from generating a failure
code in the ECU. It can also be used on older aftermarket ECU’s that expect a 0-1 volt narrow
band type signal.
The Advanced Engine Management (AEM) Wideband O2 Sensor is designed for integration ted with aftermarket ECU’s or OBD port data lorate and repeatable air/fuel ratio values. The syste AEM’s O2 Sensor Kit (single channel shown)
The UEGO controller’s ultra-compact size can be mounted in the engine compartment or under
the dashboard. It is very light and can easily be mounted with the supplied Velcro strips. The
UEGO controller should be mounted as flat as possible and should not be in a place where it will
be subjected to shock, water, or extreme heat.

There are either two (30-2301) or three (30-2300) connectors protruding from the box. The long black cable(s) connect to the oxygen sensor(s). Ensure the routing to the sensor will not come in close contact with the exhaust. The 6 pin (8-pin on the 30-3300) rectangular connector plugs into the Power/Output harness. This connector provides power to the controller unit and also contains the sensor output(s).
These can be connected to the AEM Engine Management System (EMS) or many other

The black wire is to be connected to battery negative (do not use the chassis as the power ground). The red wire is for switched +12 volts. This wire should be powered only when the ignition switch is “on”.

Typical production car O2 sensors rely on “nernst cell” technology, commonly called “Narrow
Band”, “2 wire”, “4 wire” and s erroneo describ “Wide Band”. This is a very
cost effective method that outputs a voltage based on the oxygen content of the gas being
sampled. It is accurate in the region surr etric operation and leaner.

Notes:
The sensor contains a ceramic module and should not be subject to mechanical or thermal shock
or it may be damaged.
The sensor is not designed for operation on leaded fuels, doing so will dramatically shorten
sensor life.
Long term running in the rich region (Lambda < 0.95) will shorten sensor life.
High exhaust temperatures (over 850C) will shorten sensor life.
Engine oil consumption at a rate greater than 1 quart per1,000 miles will shorten sensor life.
Do not run the engine with the UEGO sensor installed without power applied to the controller
and the sensor plugged in.

Or you could check aempower.com :P

 

thanks,

I read all that. The thing is I have AEM UEgo sensor and a gauge, nothing else. Gauge has 4 wires (2 for power BLK & Red) and 2 for output. THe question is where do I hook up those wires on the AEM EMS to use the wideband.??

 

This might help. 'Add-a-circuit Mini'

In the fuse box:
#10 is switched 12v (10amp)
#17 is constant 12v(10amp)

 

should have come with a box??

 

Yea, check the forums at aempower.com. I have a post in there specifically asking the question you are. I'd look it up for you, but I'm at work

 

Aem forums are not opperational at these times, the are moving to a different host service.

Idont need fuses, just where to splice in for AEM ems beeing able to read wideband info:?

 

So, can anybody tell me which wire on the wideband sensor goes to which wire in the ECU harness? Seems that I cant get defenite answer for that.

thanks

 

red is switched 12volts(put with an inline fuse), black is ground, white is the output to the ems, blue is unused

BTW, how's the car running or is it still rich? I thought you hooked this up before I sent you the EMS cal file?

 

I did hook up the wideband gauge and all.

Also I just had it tuned by Al and now need some fine tuning.

Do you know which wire (color)on ecu Harness I need to tap in?
thanks

 

pin 76, it's white. It's on the D plug, 6 over starting from left of the plug while looking directly into the EMS with the plug's still in it. The top part of the plug is the one with the thumb tab to remove it from the ECU. You can look the ecu pinout up if thru the AEM program file under instructions, the part number is 1313 for the ecu.

 

Thanks, Chad C. Everything is working nice now

 

No problem, glad I could help.

 

I've got a concern...

I just hooked mine up. I spliced the power (red) into the red radio line. Granted I have a few other things connected to it it turns on and appears to work.

Heres my problem:

1. When I plug in the bosch sensor it gets hot in my hand... is it supposed to heat up?

2. Theres a wining noise that comes on right as I plug in the bosch sensor. As soon as I unplug the sensor the AEM gets power but the whining stops (sounds almost like my walbro!)

Anyways, any ideas? loose connection? not enough power for the bosch?

 

I can't help with the whining noise, but the sensor is suppose to get warm. It's just the sensor preheating.
