Trying to setup narrowband simulation in dsmlink

Ok so i got an innovate MTX-L and dsmlink v3 for 1g. i have the wideband sensor installed at the stock location in the o2 housing. i got the yellow wire from the gauge soldered to the wire coming out of pin4 on the ecu which is the o2 input wire.

in dsmlink under pin assignments, i couldnt find MTX-L in the drop down menu under Connected Sensor so i chose LC1 Wideband... is that right? And i have Wideband (WB) *Front O2* (used for narrowband sim) chosen.

In NBO2 i have Enable narrowband simulation checked. i have 2.43 volts chosen as the switching point but idk if thats even right for an mtxl

Delay is still set at 15 sec
"and until WB not equal to:" is set to 0 +/- 0

When i turn the car on, the gauge lights up. i did calibrate it in free air. it reads around 14.5ish on idle which is fine.. the problem i have is when the car is on, the voltage just stays pegged at .80v and never cycles like it should. i dont know why. yellow wire is soldered into pin 4 wiring like it should be. so idk whats wrong. one thing i am confused about regarding connecting to pin 4, is should stock wire be cut and left unconnected so that the yellow wire alone connects to pin 4? or should it be spliced in like a T connection like i have it setup currently, where the stock wire to pin 4 is still connected and the yellow wire is just soldered to it.
 
As long as the factory defaults are programmed in the MTX-L then 2.45 is the exact voltage output for 14.7 afr which would be the switching point so you got that right and the yellow wire is the 0-5v output so that is right also. You should cut the pin 4 wire so that the only thing it is connected to is the 0-5v wideband analog output wire and not the factory o2 sensor.

Thanks for the reply. The factory o2 sensor is not plugged in. it was unplugged and replaced by the wb02. but i could not get the narrowband simulation to work :/ idk why.
 
Everything sounds right to me. I'm not familiar with narrowband simulation in DSMLink to know if this makes a difference, but have you let the engine warm up to where it will switch to closed loop?

Yeah it was at operating temp. (190ish)
 
Figured out the problem.. im a dumb*** and read the pinout pic backwards so i had the yellow wire connected to pin 9 instead of pin 4. epic fail.
