I have been struggling with this for two days now. The AFR gauge in TS will not recognize my MTX-L. I have tried putting the project setting for the wideband as LC1 default and afr calibration as LC1 default. When it is like that it says my afr is stuck at 7.3 in TS but the gauge on TS shows it is stuck at 19. Then I tried changing both settings to Innovate 10-20 afr 0-5v. With those settings TS shows my afr is stuck at 10. I have the yellow wire hooked up to MS in the db15 connector on pin 15. Weird thing is the car runs exactly the same if the db15 connector is plugged in or not. I am seriously lost.

Do you have the O2 sensor setup set to wideband under Project Properties?

Ryanxstorey

Yes I have tried a few different ways. Tried setting the project properties to innovate 10-20 afr 0-5v and same thing under afr calibration. Then I tried putting both setting to lc1 default. And ego control is set to wideband.

If this is a brain-built DIYPNP, then I think the wideband wire in the DB15 is in pin #4, not #15. Open up the ECU, take a couple of good pictures (top/bottom) and post them here.

I think he did buy one that I built, so yes pin #4 for wbo2 input. #15 would be ebc out.

This is built by brain. I bought this from a friend brand new who bought it from brain. Friend never used it and bought it for the car I now own. I'm at work and will post pictures of it later. Thanks a lot for the help.

All three of you are awesome this has been the last thing that has been hanging me up for the past few days. I should be able to get my car tuned now.

One last thing. Braineack what settings should I use with the mtx-l. I saw you manually put your voltages and afrs when calibrating.

Braineack

i typically use .22 - 7.35 and 5v - 22.39 on the MS. with the MTL-x using the default 0-5v 7.35-22.39 output.

Ok thank you. And under project properties should I use the lc1 default?

Braineack

iTrader: (62)

no, custom and plug in those numbers.

Ok so I moved the wire to pin 4 and changed my settings. I changed my setting under project properties to the selection that says other wb not specified (something along those lines) then went to calibrate afr and used custom wb and put the numbers you said you used for ms. Burned it and now the afr gauge on ts is stuck at 6.8.

Bump for help.

your stock o2 is unplugged? which mtx-l wire did you put into #4 yellow or brown?

Ryanxstorey

iTrader: (2)

The stock o2 is unplugged and out of the car and I have the yellow wire plugged into pin 4.

Braineack

and what happens if you try lc1 default?

With lc1 default settings in tuner studios it says the afr is 7.3 but the needle on the gauge in ts is on 19.
