A wide band is a “MUST” for all turbo cars because nothing melts a piston faster than a wrong setting by increasing boost. Running low on fuel is a catastrophic situation that leads to major damage to your engine and we all know the costs associated with building a new engine! What does a broadband do? A broadband UEGO (Universal Exhaust Gas Oxygen) sensor controller accurately monitors air / fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage.
We compiled the following article to show you the correct way to install the broadband, the installation is quite simple and should not take more than a couple of hours, remember to decide in advance the route you plan to use for the wiring to ensure a clean installation.
The first thing to do before installing the UEGO is to change the meter settings (faceplate and bezel)
Place meter anywhere within 2 “hole (pillar or custom mounting location)
There are 2 wire harnesses with the kit. The short is used for the functions in the meter and the longer is connected to the UEGO sensor.
Connect harness 2 to the back of the meter. (6-pin and 4-pin)
Run the longest harness through the firewall.
Use a C-shaped bracket to tighten the gauge at the back.
Disconnect the negative (-) battery cable.
Remove the downpipe and weld the M18x1.5 error at least 36 inches from the exhaust side of the turbo and at a 10 degree (minimum) angle.
Screw the UEGO sensor into the downspout plug.
Connect the end of the UEGO sensor to the end of the meter’s 6-wire harness.
Now it is time to connect the 4 pin harness.
-RED (Power) Connects to a 10v-18v power supply.
-BLACK (Ground) Connect to a clean ground point.
-WHITE (analog output) Connects to any auxiliary unit with a 0-5v input.
-BLUE (serial output) Connects to an RS-232 communication port. (This output is optional)
Reconnect the negative (-) battery cable.
Start the car and let the engine warm up for over 20 seconds, now you are ready to start tuning!
