MXT-L WB fresh out of the box

[preludeachris]

This is my first WB install anyone running the same thing? Pointers would be useful also if someone could point out a thread about wb install so I can get a print out ...my buddy has a wb in his supercharged civic and his going to help me out but a reference would be nice


This is what I got sent

I have installed this in my 1g it's pretty simple 12v power i used my cigarette power so it comes on when my key is turned on and black to ground. i have the directions here in front of me it states

RED: 12v power
BLACK: Ground
White: Headlight power wire that supplies current to headlights (DO NOT CONNECT TO HEADLIGHT DIMMING) If you choose not to utilize the dimming feature connect the white wire to GROUND
YELLOW: analog out and/or Brown: Analog out 2 can be connected to data loggers or ecus. if either or both not being used isolate them and the the wires out of the way
the default analog outputs are as follows: analog output one(yellow) is 0v=7.35 AFR and 5v=22.39 AFR. Analog output two(brown) is 1.1V=14 AFR and .1v=15AFR this is a simulated narrowband signal

CALIBRATION OF SENSOR
1. The calibration procedure requires that the oxygen sensor to be in FREE AIR , not in the exhaust.
2. With the sensor disconnected from the MTX-L, apply power to the MTX-L. When power is applied, all three digits will light up and the needle bar will turn red and them numeric display will sweep once though all the LEDs. Then the status light will turn red and the numeric display will read "E2" this is an error code, indicating that no sensor is detected. leave the unit powered on for a minimum of 30 seconds.

3. POWER DOWN the MTX-L and attach the oxygen sensor using the cable provided. Again make sure that the sensor is in free air (NOT IN THE EXHAUST)

4. power up the MTX-L

again the display will sweep but instead of error the display will read "Htr" this indicates that the sensor is being heated up to operating temp. after 30-60 seconds the display will switch from "Htr" to "CAL" indicating that the sensor is being calibrated. A few seconds later , your MTX-L will begin displaying AFR. Since the sensor is in free air the gauge will default to the upper limit of 22.4

THE CALIBRATION PROCEDURE IS COMPLETED AND READY FOR USE NOW

Are you running ECMLink? If you are then I would suggest putting it in the front O2 position and simulate the narrow-band signal in Link.
There is even a simulated narrow-band output wire with the MTX so you can still put it in the front O2 spot and just hardwire that sim' output to your front O2 pins on your ecu.

The next place is on your downpipe before or just after the flex joint by welding in a bung. Some people put it in the rear O2 position but the general consensus is that the response time is too slow using that location.

narrowband simulation is only working for v3 lite and full. otherwise, i installed mine in the rear o2 bank, and tapped the brown cable into pin 75 (rear o2 input) and logged the rear o2 voltage. i connected +12v to the cigarette lighter fuse, and the dimmer cable (white) connected with ground cable.

running the sensor i put it underneath the drivers seat where the original o2 sensor wire came through and ran it under the center console and have the plug sitting under the ashtray area.

cool thanks for the tips.

so basically I can just put it in the front o2 and simulate? Why does it seem like I have so many wires to hook up?

PS yes still running link

if you have link v3 you can put it in the front o2 spot, connect the yellow wire to pin 76 and simulate narrowband in link.

You can do it with v2 as well but you need to splice into both front and rear o2 pins, and let the mtx-l replace both stock sensors. Its outputs are programable to whatever you want.

Just one more thing with this MTX-L wideband the colors for the LED sweep and the digital readout is programmable to whatever colors you want. The cable in the top right hand corner of picture #3 is the cable you use to change colors and there should be a CD that came with it also.

that's what I'm doing. I have it in my 02 housing. No need to worry about 2 o2 sensors.

narrowband signal from the gauge goes to the front o2 input, and wideband signal goes to the rear o2 input for logging.

I have it wired into an ignition 1 source, so that when you crank the engine it doesn't lose power.

The best part is that it uses the same o2 sensor as an 02-05 jetta 1.8t. Same plug and everything. So if it ever dies, you can get a replacement cheap
