I've just got a quick question about installing a innovate mtx-l wideband, I've read through all the threads I could find on the subject matter and couldn't find a definite answer on for my question. I'm wondering if I can run one with a factory ECU or would I need say ecmlink or AEM EMS to install it? I do know that with ECMlink you delete the Factory narrowband O2 and re-pin the Wideband O2 in its place but I'm unsure if the methods apply with a factory ECU as I will more then likely need to delete the Narrowband O2.
Hope this isn't a stupid question but like I said I couldn't find a definite answer.
The reason I'm installing one is I'm leaning out as some point in the rev range, can't find a boost leak to speak of and am hoping this will help me narrow my search as to what it might be.
Hate starting another dumb thread but help's very much appreciated![DOUBLEPOST=1415244750][/DOUBLEPOST]Never mind I found the manual online at it of course answered my question

You can install this in place of the factory O2 sensor. The gauge has to signal wires, 0-1v (BROWN WIRE), and 0-5v (YELLOW WIRE). The 0-1v wire (BROWN WIRE) will have to be connected to the engine harness. Cut the factory o2 wire at the ecu and connect the brown wire to it.

It will work just like stock. In the future when you wish to log the true o2 wideband voltage 0-5v (YELLOW WIRE), you can always connect it to another pin. Rear o2 wire is commonly suggested.
 
Except if you read his post, he's asking if he can run the o2 like stock, on a stock ecu. No Ecm link to compensate or Aem. Therefore the link you posted doesn't help him as it says not to use the 0-1v (brown wire). Which is the very wire he needs to hook up.
 
The Innovative MTX-L supports native narrowband simulation. It will function in the front o2 location with a factory ECU, it's the logging of the wideband data that you will have to figure out if you do not yet have a form of tuning/fuel management.

Don't patronize me Mr. 16 posts, I read what he wrote just fine. Should I have spoon feed the OP the information? The yellow wire is clearly the WB output (0v - 5v) as noted in my post, so by a 50/50 process of elimination, the only wire left that supplies an O2 signal would be the brown narrow band output. I'll break it down verbatim for you next time.

There are 2 additional things to consider when using an O2 sensor other than stock. The first being the output voltage of the aftermarket sensor. Since Innovate says their narrowband output is 0.1v - 1.1v, you should be fine since the factory sensor's output is ~0.2v - 0.7v. Just be aware, not all sensors are the same, and you may experience variation in your readings if the output voltage deviates too far from what the stock sensor output is.

Second, the output wire that runs from the stock O2 sensor to the ECU is shielded for a better part of its path through the engine bay. I would recommend cutting the plug off an old O2 sensor, and wiring that into the new sensor. This way, you retain the shielding in the factory harness, and get the most accurate readings. It will it work by running a wire directly to the ECU, but it's not the best way IMO.

Hopefully, this isn't too confusing for anyone.
 
Meant no disrespect, however you asked me not to "patronize" you, and your last post was nothing but patronizing from the first sentence to the last.
I only meant to help the OP. You want to have a pissing contest, start another thread.
 
Im doing it right now(noy by choice, dsmlink out for repair)... it works fine.. after about 2 days driving i got a cel for o2 sensor but its monitoring everything. Stock ecu runs like crap btw LOL.. idle rich and drive lean
 
wow guys, sorry for not replying it was like a month with out an answer so I just disregarded the thread completely.
Thank you all for replying you've actually all helped a lot, I still have yet to fully install the wideband as I was unsure if I could delete the factory narrowband o2. Now my questions been 99% answered. I do have the gauge completely wired in and powered up but don't have the o2 sensor in. I just swapped on a tubular o2 housing with wg dump the other day and my o2 sensor didn't like that I guess because my CEL is now on...... was just going to swap in another o2 but if I can finally hook up my wideband I'll be in heaven!

@GST with PSI- I did actually read your article but was unsure if it was also directed at mtx-l as I seen LC2 system which I know I didn't get so I kind of disregarded your write up not knowing if they were completely compatible. But thank you I now know! Its not like I didn't do research tho I spent a few days looking, guess I should have researched the products more before searching for an installation guide haha.

I've been fighting over boost issues like mad so I'm also working sorting that issue out as well. Order a MBC the other day to hopefully help me out.
Guess I should have posted more info on my car! derp!

92 1g
7 bolt
AWD
modds
EGR delete/block off
ported 14b turbo (currently over boosting to 20 psi and leaning out hard)
tubular o2 housing w/wg dump
balance shaft delete
Fidanza flywheel
southbend stage 2 clutch kit
Yet to be installed
walbro 255
fuellab FPR

My main thing is I just don't want to go lean, as I already have a problem with that LOL.

Remember that by installing the wideband in place of the OEM o2 sensor that you will get a CEL for the "heater" circuit. After giving it some thought, i was wondering if you could use the heater circuit to power up the wideband to satisfy the heater circuit and avoid the CEL at same time.

Install that Walbro 255 ASAP or lower your boost.
The stock fuel pump can barely supply enough fuel for 15 psi boost. It cannot supply enough fuel for 20 psi. Also, the stock 1G MAF will usually overrun at about the same time that the stock fuel pump reaches it's max. Both will cause a lean condition.
 
Oh believe me I didn't want it that high! I looked into what might cause it yesterday so I'm now running wastegate pressure at 10 psi, my actuator solenoid appears to be bad causing the high boost. (definitely notice the difference between 20 and 10 psi haha)
Waiting for my MBC to come in as well for a way to control it apart from the actuator solenoid. My boost gauge also crapped out on me yesterday...only 3 months old!!!

Actually I'd have to install the fuellab FPR as well as the walbro 255 would be very likely to over run the factory FPR. I did notice it was right around 14-15 psi when every it would break up. I also have a 2g MAF (not installed) but don't have the connector or a translator to compensate for it.

Ok just doing a conclusion to the thread

Yes a wideband O2 can be installed in place of the stock narrowband O2 with out a ECMlink, AEM EMS or Halltech or any other sort of after market engine management system installed in the vehicle.
It can be run on a STOCK ECU

A Innovate MTX-L is classified as the LC-1 (which is where I got confused)

For Running narrow band simulation on stock ECU(aka deleting OEM O2)
On a 1g DSM simply pull both sides of the carpeting that surrounds the centre console out. Undo the "3" 10mm head bolts holding the ECU in and pull it towards the passenger side foot compartment (will have to turn the ecu completely on its side connectors facing the drivers side of the car). Take the biggest ECU connector (C-61) disconnect it from the ECU. Find pin number 4 (Oxygen Sensor Input) it will be a white wire cut it a few inches up and connect your wire feed for the BROWN wire.
The rest is self explanatory for installing the gauge and Wideband O2.

You must be logged in to view this image or video.

I suggest labelling/colour matching all your wires you extend from the original gauge wiring as it will save confusion down the road.

Here's some links that give a lot of information and should clear up any other questions people might have.

I've seen that on pump gas and the wideband sensor in the stock O2 housing location it's ok. But once you run race gas like 110 or even 100 oct it to close and the sensors die faster. I think right before the flex section on most downpipes is the perfect all around spot. I plan to set mine up that way from now on atleast. From what I've read the sensors are getting better and last longer. We will see.
