Now problems with Innovate MTX-L

[wheming]

Well its always something.
Still waiting for more ideas/fix for MPScan not working for me and i figured i'd clean up the van a bit.
On startup and idling i noticed my mtx-l is flaking out. It dances around quite a bit and hits full lean. Never would do that before. This was happening even when in open loop mode.
Going to try and do a sensor recalibrate on it and see if that works.
Somtimes i think i would be better off to just keep the stock narrow band O2 sensor for the ECU and use the WBO2 for just information/datalogs. I might do that when we get the MPSCILink.

So with this going on, and mpscan not working, looks like no racing for me tomorrow.

Well tried sensor calibration twice, and still acted weird. I even got a code E4 one time when it was powered on with the key on ACC and engine not running (normally it would read).
So i tried my spare sensor i had.
Calibrated it, installed and tested. Reads normal again. No fluttering around and reading intermittent 22.4 when in cold start.
I better order up another spare...

I was glad it wasn't the other cable. Didn't have a spare or want to remove the one from Slug.

I used MTX-L, nothing but issues.

Change to AEM uego 3 years ago, used the same bung, not a single issue since then.

[wheming]

The sensor is the same also?
I may have to consider that if i have reoccurring issues.

Do you use it direct to the ECU or use a NB as well?
AEM recommend to install a long way (36") from the exhaust port if you have a turbo

I used the 0-1v from both MTX-L and Uego to connect to the ECU. It's especially frustrating when the MTX-L was malfunctioning.

I was looking at the AEM product page, and it said there was only a 0-5v output and only measures AFR 10-20. They use the same sensors bosche LSU 4.2 or 4.9. The newer model 30-4110 uses the 4.9

The MTX-L is capable of using either sensor, but you do need the latest firmware update v1.04 to switch sensors and must be setup in logworks for the proper sensor. The cables are different between the two however.

AEM marketing team did a bad job. AEM UEGO only have one analog output instead of two as the Innovate. There is a switch you need to turn to select to get the 0-1v (P4) out of the analog output.

Yes, AFR 10 to 20 is the limit, but if your car is out of those range, you got bigger issues.


My friend for some reason like his Innovate stuff. Whenever there is a trouble with his gauge, he's bring out his laptop to upgrading the flash files or getting under the car to take the sensor out to re-calibration while I have done NOTHING other than install the UEGO and UEGO works every time I turn on my car.

In my experience,

Innovate have two analog outputs.
Innovate works most of the time.
Innovate can be calibrate using sample air. (Frankly, I don't see any other OEM car manufacture asking their customer to get their wideband calibrated every 3 months or 10,000 miles)

AEM only have one selectable analog output.
AEM works every time.
There is no calibration needs to be done.

Techedge is a good unit, I've had one for about 8 years now and I've never replaced the sensor. With the Australian exchange rate you can buy one for a decent discount.

There is no calibration that can be done. UEGO can only be calibrated at the factory, and it is calibrated to that particular sensor- replace the sensor and its no longer correct. ALL wideband o2 sensors lose their calibration over time- Innovate reccomends recalibration every 6 months.

There is nothing wrong with Innovate products- every single failure i've seen is a result of improper installation.

[tryingbe]

Way too many failures to be improper install.

I'm ok with AEM being slightly off vs Innovate not working. The video I posted was my Innovate.

[contraption22]

I am getting an E4 code when I powered up my SECOND MTX-L. I will try calibrating the sensor, and putting in the spare.

[wheming]

That reminds me, i need to order a spare sensor!

That thread is 4 years old. Innovate has released the 2nd gen of their widebands since then. failure rate for the new ones is miniscule.

[tryingbe]

The bad taste of Innovate has not wash away from my month, and I doubt it ever will. I will not use an Innovate product, even it is free. The above video should show you why. I have the AEM UEGO installed at the same power wire, same ground wire, same ecu input wire, same o2 sensor spot, gauge at same location and no trouble whatsoever for the last 3 years.

[contraption22]

Tried my spare sensor. Still getting E4 code. Some people have been lucky with Innovate. I am not one of them, and I am not alone. 2 failures before the car leaves the driveway. I would call it installation error if it didn't work for a short time. FU Innovate.

My comments/questions aren't meant to bash, criticize, or promote Innovate.
Is your gauge installed how they recommend? Power from battery through a relay if you don't have a power source free of noise/fluctuations. Is it grounded back to the battery, or a verified ground that is just as good without stray voltage?

If so, then it probably is a problem with the unit. The E4 code is for bad sensor or bad cable to the sensor. That could also mean something in the controller itself i imagine.
Did the new sensor work at all? It fixed it for me. The new sensor needs to be calibrated as i'm sure you are aware. If you still get the code, you might have a bad cable.

[contraption22]

Yup, it's installed as per the instructions. I replaced the cable. Now the code is gone and the unit calibrated. No signs of damage to the cable.

I figured if i get another failure i would try the newer sensor lsu4.9, but that requires a new cable.
But hopefully i'll be ok a while. I have the same unit in Slug, so i keep an extra sensor.

I got my mtx-l working again. Poor connections. Innovate are really sensitive which makes me question the idea that unit to unit, install to install, they are consistent or accurate. I like electronics that can deal with an Imperfect world. That is where I live. I want a super cheap wideband for wife's car that never needs to be worried about.
