I just hooked the yellow wire analog out 1(0V-7.35 and 5V=22.39) (single with no ground) to the first pin on the MPVI. Starting scaning and was close to MTX-L gage reading. Had to offset (-.2) and now is dead on.
Good luck and let me know if you are hooked up.

It was really easy. You will just need a really really small flat screwdriver.

So the only wire going to the MPVI is the yellow wire? I have the yellow wire on the first input and my positive and grounds going to the battery with a 5amp fuse on the positive. The wideband works great but when I'm logging the readings never go past 14.0-15.0 afr.

Thanks for the help!

Having a similar issue with mine also :(
Setup HP Tuners and LM Software wit the same readings for Voltage and mine never reads more than 10AFR on HP Tuners but reads 14+ on the gauge.
Quite irritating :banghead:

I have someone helping me and when I send the log files it logs 10AFR :(

Not enough information to help.
Have you created a user defined PID?
Have you created a histogram for the PID?

If yes How did you set the above up?

is there a way to use the serial/usb output of the mtx-l gauge with the scanner software? it would be a lot easier if the scanner software would recognize the data from the gauge through a usb cable to the computer.

Did anyone setup or use this damn WB? cant find dickall for info on setting it up in the channels.
Is it the same as the other Innovative lc1, lc2 or is it like this: (input/ 5) + .5 = output

It will show you how and will show you how to set up the offset.
Good luck.

i too have the mtxl and am trying to get it to log via serial comms. it seems as you can get a rs232 serial to usb and plug that cord into the serial data cable the mtxl comes with and then somehow setup the usb input as the wideband.

did you ever get it figured out ??
