I just checked the factor again going off of Zeitronix published 9.6 AFR @ 0v and 19.6 AFR @ 5v.
Without any rounding I get a factor 0.009765625.
The difference is only 0.000374 AFR using 0.009766.
How old is your Zeitronix? Pre 2010 they had a non-linear voltage output.

My ZT-2 was bought in 2012, so its got the linear output. I have added the WBvoltage to my ME7logger so I just need to log with my ZDL at the same time. Hopefully I'll have some time tonight.

It doesn't even need to be logged concurrently.
Just compare ZDL voltage = xAFR vs ME7 voltage = yAFR
The factor for 0-5v ADC in ME7 is 0.0048828125.

I just checked my logs and I don't have WBvoltage in my ZDL logs. I'll have to play with the settings.

I don't have any issues with my zeitronix but then I don't use their gauge (which might be set up wrong or somehting).
My zeitronix feeds PODI gauge which is set to Zeitronix published sclaing for linear output, car sits reliably at 14.7 when idling at the gauge so it checks out in that respect.
Then the same wire feed rear O2 input and when voltages get converted to AFR/Lambda, the value is exactly 14.7 as well.
What is your zeitronix showing at idle? Seeing that you claim that ME7 shows rich, I bet that your zeitronix shows something over 14.7 (14.9?) when idling... If that's not the case, maybe you need to check wiring as you might be dropping some voltage on iffy/corroded connections and showing richer than it really is...

Not sure what I am doing wrong here in regards to modifying the .ecu file Here is before I adjusted the .ecu file ushk , {O2SVoltageSensor2} , 0x380A91, 1, 0x0000, {V} , 0, 0, 0.00521569, 0.2, {Spannung Lambdasonde hinter Katalysator}
ushk2 , {O2SVoltageSensor2Bank2} , 0x380A92, 1, 0x0000, {V} , 0, 0, 0.00521569, 0.2, {Spannung Lambdasonde hinter Katalysator Bank 2}
And after ushk , {WidebandAFR} , 0x380A91, 1, 0x0000, {V} , 0, 0, 0.01043138, 10, {Spannung Lambdasonde hinter Katalysator}
ushk2 , {WidebandAFR} , 0x380A92, 1, 0x0000, {V} , 0, 0, 0.01043138, 10, {Spannung Lambdasonde hinter Katalysator Bank 2}
Using an AEM wideband (0v=10AFR, 5v=20AFR) and the ME7L is showing -8.7xxxxxxxxx |

I think you need to use uushk_w and uushk2_w.
and
AFR:
Factor : 0.00976
Offset : -10

Are the addresses in the first post for an mbox sw0002?

Thank you for this, makes a big difference. Tested with AEM Uego, works perfect!

Has anyone noticed a difference between ZT-2 AFR (reading off my gauge) vs. ECUx logs through the rear o2 input? My ECUx logs are about 0.2 AFR richer than actual AFR read though my gauge and recorded in my ZT-2 logs. I attached a log from last year. I'll get some fresh logs though.
My ECU file has a factor of 0.009766 and an offset of -9.6 as instructed. I attached the comparison excel sheet I put together along with the logs. In the compare file, see the various sheets 1-4 for each gear logged while I was at ATCO dragway last year.
Holy thread revival again, but yes I do have the same issue. Can't figure out why... |

Same. I have had zeitronix bang on, .2 lean, .5 rich, etc. I use innovate now. Always perfect. |

The million dollar question is.... which one is correct?  |

I would not waste another $200 on just innovate because of this. I am starting to think that the AFR conversion is just wrong, this can't be a wiring issue, it's directly wired to the ECU with OEM terminals, and a lot of people use Zeitronix's wideband output without these issues. The difference is always there, closed throttle, cruising or WOT. I will log lambda today instead to see how that behaves and then raw voltage. The attached picture shows how i am cruising at 14.5 and closed throttle is 19.5 while i see 21.00 AFR on the display. Yes using AFR is bad I know  |
