Doesnt this also require some kind of rear o2 sim or patch thing added to the rom xml? Thats what I keep reading in different threads but there is also tons of different patches/sims/methods/instructions, all of them being 8-10 years old so I dont know what info is even accurate anymore. All I want to do is log afr in evoscan for tuning and not have a CEL. I have a stock 88590015 rom.

Flash tephra v7 so dont have to go through above.
I've considered going to tephra for the additional features. My concern is that tephra has a lot of tables that the 8859 does not have and I dont know what values should be used since I cant compare and copy from 8859.
Would I be ok just switching to tephra and only copying the tables in 8859 but leaving the others untouched? I've read the "How to set up tephra" which explains some of the new tables and what values to enter, but not all of them.

Thanks, that helps a lot. So I can either use the combined patch in my 88590015 rom or I can just change to tephra v7 and the patch is already pre-applied to the rom?

If you are all stock just flash the v7, let it idle for 10 minutes and log.
Make changes accordingly. Keep reading, this forum has alot to offer.

What values are you using for the "RequestID" and "ScalingFactor" in your evoscan data.xml? Im using a AEM UEGO if that matters.
In this example, the OP is using RequestID: 12 and ScalingFactor: 1 https://www.evolutionm.net/forums/ec...ial-cable.html
In this example, the OP is using RequestID: 3C and ScalingFactor: 10 https://www.evolutionm.net/forums/la...o-evoscan.html
What should I be using?

These are my settings for AEM eugo divital wideband (oldschool one) and they worked perfect for anyone looking for the proper formula. however I just ditched the eugo and got the new X series aem wideband with 4.9 LSU sensor, does anyone have the same info for this new gauge that I am posting for the old? Thanks looking for the eval equasion as well as the max and mins. The new aem gauge reads 8.5 rich to 29 AFR lean

Make sure to wire the Brown wire to Sensor ground in the ECU, NOT chassis ground.
