So I got the wideband installed and took pics. Went rather smoothly since there was already a bung on the exhaust and I already had a spot for the gauge. Overall, I'm happy with it. But I'll just get right inot it.
First things first, find a switched 12v source
Find a headlight power wire, I already have gauges over here so I tied into the wire supplying them.
Once I located the neccesary wires, I disconnected the battery
This is the oil temp gauge I no longer need, so the Innovate gauge will take its place.
MTX-L installed
Red wire on MTX-L goes to switched 12v, which is this green wire supplying 12v for my other 2 gauges
Again, white wire on MTX-L goes to headlight wire, which is this thicker white wire supplying switched power for the other gauges lights. This wire works differently for the MTX-L . It dims the display when lights are turned on so it's not too distracting at night. If you don't want the display on the gauge to dim when it's dark and you turn your lights on, then ground this wire to the chassis.
Black wire on MTX-L is the ground wire. Keep it away from radio grounds or anything similar that has a lot of "electrical noise". As per the instructions, it could interfere with MTX-L unit, similar to the reason MAF wiring is shielded.
The yellow and brown wire are analog outputs for either your ecu or datalogging, I will be using these later but for now not neccesary. So I individually heat shrinked them, then heat shrinked them together.
So here's the wires behind the glove box area. I'm not worried about how the wires look now as I have a few more things to do under here, so it will get cleaned up in later this week.
Before you hook up the actual sensor to the MTX-L, the unit needs to calibrate itself. So now that everything is wired up, hook the battery up and switch the car to accessory or on position. The gauge will cycle on lighting up the entire digital readout and sweep the light bar across the enitre spectrum. The it will show E2, which is error code for no sensor, which is great because the O2 sensor not plugged in yet.
Then the car gets turned to the off postion or just remove the keys, the O2 sensor gets plugged in and is allowed to sit in the open for a "free air" calibration. So I plugged it in and set it on the box to keep it off the ground.
Turn key to the "on" position, no need to start the car. The gauge will show "Htr". This is the sensor heating up so it can get accurate readings. I took these 2 pics because as the method the gauge uses to display the reading, the camera catches it in between it pulsing the readout, weird. It only looks like this in a pic. It shows a constant display to the human eye.
After 30-60 seconds it will display the reading which will be 22.4 because that's the gauges upper reading limit of lean and since the gauge is sitting in open air that's correct.Now power the car off again and it's time to mount the sensor. You can unplug the sensor and you won't have to recalibrate it as long as you do not power the car on while it is unplugged.
Time to make a hole
After about 5 minutes it finally punches through. Here you can see the bung that was already in the exhaust for me as well. Score!
Painted the hole and applied some gasket maker.
Then a rubber gromet and more rtv.
Found this old broken scope cap that I filed a slot in, then used another grommet to help keep the water and debree out.
Slit the small grommet, slipped the wiring into that, generously applied more rtv and placed the whole ensemble in place.
Then sprayed it all black.
Everything went relatively smoothly especially having the bung already in the exhaust. Had an old broken O2 to keep it plugged. Old on the left, New on the right.
If anyone has any questions on it feel free to ask. I'd also like to point out that I got the MTX-L with the 8ft sensor cable option. Needless to say i have about 4 ft coiled up under the dash but when I use it for dyno tuning it will come in handy having the extra cable. They offer it in a 4 ft cable which would be fine, should be able to mount he gauge any where on the dash with the 4 ft option. Thanks for reading.
