I have the MTX-L in my jeep. I tried for a while, running my pcm with the simulated narrow band output. It would work fine for a few days then I would get a o2 sensor code pop up. I would have to reset the pcm to clear the code and then be fine for a few more days. I eventually went back to a regular heated narrow band.
It could have been the voltage range the MTX-L was putting out was not exactly what my pcm was looking for, but I could not find the exact range I needed it to put out and at what afr to program it. So I just switched back to the NB.
My system is a OBD1, 16197427 system, so I am not sure if obd2 would be different.
