I think you'll be fine with new conversion values. They are spot on and agree with zeitronix sitting in the same exhaust stream.

Just thought I would report that those new conversions are working nicely for me!

Just sorted using this and I only get a steady reading of 9.6 throughout the rpm range no matter what I tried.

I'm using an AEM UEGO sensor with gauge.  I have the 0-5v output plugged into my ppd and it works great but I cannot get anything other than 9.6 in my me7logs.

I have checked all my connections and everything looks good.  Have the same 0-5v output from aem to black signal wire on rear o2 brown sensor. 

Any help?

9.6 is indicative of no input.  Are you logging the correct bank?  The logged address may be incorrect.

I will double check!

I did check and I am logging the correct sensor.  Is there something my tuner needs to enable for this to work?

All I have is my rear brown o2 sensor cut off the cord.  Spliced a wire into the black wire going into the plug for o2 sensor at harness.  Then that wire goes to my 0-5v out from my wideband.

I should also specify it's for an rs6.  Maybe address for rear o2s is different on me7.1.1?

The address is different for every file, let alone between ME7.1 and ME7.1.1.

Post your file.

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.

You lined up raw voltages and compared converted values?

No, I have not logged raw voltages. But I compare my Zeitronix log and my ME7 log, I notice that my ME& log is always richer than my Zeitronix log. I also have noticed this while monitoring my digital AFR gauge. I am expecting 11.7-11.8 AFR based on my ME7 logs (I usually don't log with my Zeitronix logger), but my AFR based off my gauge is around 12.0.

I'm going to log and compare raw voltages today.
