Re: Innovate MTX-L Wideband O2 Sensor ISSUE
As in grounding the mtx-l to a ground that is going direct to the PCM?

yep that would be a good test

Re: Innovate MTX-L Wideband O2 Sensor ISSUE
Okay so I have now test with multiple ground locations and all of them give the same result.
This is a photo of the wideband percentage difference for correction of the AFR's, you can see the wideband is 14.0 in the background

Looks like a incorrect formula. There should be no minus figures.

The formula is right, the analog output the ECU is reading is inaccurate of what the gauge is reading. when u change the formula to match its fine, then try to log again and the numbers dont match

Measure the voltage going to the ecu and see if it's a reasonable voltage like 3 volts etc. If it is make sure your using the correct logging file. I have never seen negative values with any log I have done. It should show 7.35 volts with no wideband input and up to 5 volts with a very very lean mixture like 22:1. You are using the yellow wire for the output to the correct ecu input?

Re: Innovate MTX-L Wideband O2 Sensor ISSUE
Iv just measured the voltage to the PCM and its 2.1v when the gauge is showing 13.4, i also removed the sensor and while it was in fresh air i reset the cal and when it was reading 22.4 i took another reading and it was 5.09v so to me that all seems right. It must be tunerpro setup?

I am only familiar with 12P and 11P and the formula is x/10.

post up your ADX so we can confirm what you have in there ?

Re: Innovate MTX-L Wideband O2 Sensor ISSUE
oh hangon, just looking at your pic ..... from what I can see that table is a calc to offset ..... so its using the wideband reading and the commanded AFR and giving you the difference, that's why your seeing negatives!
still if you post the ADX I can sort it out so you have the histogram you want ? also if you have a log post that with it.
