I'm reading the manual and it says that I should be able to use the WB sensor instead of the OE sensor. It must be used in the right format for the ECU....but this is what I am reading:

Connect ECU to following MTX-L wiring:

Analog Wire 1 (yellow) -- 0v = 7.35 AFR 5v= 22.39 AFR
Analog Wire 2 (brown) -- 1.1v = 14 AFR 0.1v = 15AFR

In the Narrowband section it mentions using Wire 1(yellow), but should I ACTUALLY use Wire 2(brown) since MB uses 0-1v? Any ideas?

Are you using the WB sensor for just a read out or for control?
The brown wire appears to give you a narrow band output which your CIS-E /EZL needs for control.

The yellow wire appears to be a wideband output which can be used for read out or control setup.

I still run a OEM narrow band in my TwinTurbo as it maintains the stock control of the CIS-E/EZL.
A wide band is installed in another bung but was only used to program the fuel maps in the stand alone enrichment controller.
The variable in my control that enriches under boost is the manifold absolute pressure and no O2 sensor input.

Check with the manufacturer to see if you could use both outputs, the brown for stock control and the yellow to your AFR gauge.

It actually does not mention using the yellow wire at all for standard readout, so I am hoping that means the controller will still output the full range -- the analog is simply there for adaptability. That would be cool!

Where did you weld your bung at, just curious? The exhaust shop said it was a difficult job. I may try going to some "on-the-side" shop.

The bung for the stock O2 sensor was factory installed before the middle silencer.
The down pipe had to be cut from the middle silencer to install the spun metal cats.
So the stock bung is on one pipe and a bung for the wide band was installed in the same location on the other pipe prior to installing the exhaust.

I like the AEM for ease of use/install. You hook it up in the same manner as a narrow band... bung, run wire, switched 12V, and ground. That is all there is to the thing. Yes, it has analog out so you can log with it or run on MS.

I had used an Innovate a while back, but then you had to calibrate it after so many hours of use and such. :rolleyes: Perhaps this has been corrected?

My Z71 has a Tech Edge, but I bought that forever ago and just needed one to log only with no readout.

The sensor alone now is cheap, around $40-60.

the scorpion stainless exaust, that was supplied with the tt kit is 2.25"

Thank you kind Sir...
I graciously stand corrected :)

If u on a real shoestring budget like me. You could try the fong kong. I found it for 150 usd shipped, here www.deporacing.com. Thats for the sensor and the guage with readout. But im so broke i still need 2 save up for it :-(
