My goal is to wire AEM Uego without using serial cable.

Am I supposed to see a patch in 96530706 XML file to use this feature in this ROM

All you need to do is:

1) Activate Rear O2 simulator from Tephra options

2) Add following patch to your 96530006.xml to disable rear O2 heater cell (set Rear O2 Heater Cell Enable to value 0 to disable cel):

After these two steps you are able to completely remove your rear O2 sensor and wire your AEM analog output to rear O2 input. You can then datalog AEM voltage from MUT 3C and with correct equation from voltage to AFR you are directly able to datalog AFR with ie Evoscan.

 

do i follow the same procedure if i wanted to delete my rear o2 sensor?

 

on a 96530706
that is

 

That is the procedure to completely remove rear O2 sensor if you are using 96530706 rom.

 

is it the exact same code for 96530706

 

Yes because v7 roms are based on 96530006 rom

 

ok great. i will give this a try today.
how do i confirm that it is in fact working? would unplugging the rear o2 normall throw a CEL?
and lastly, would o2 delete affect my tuning? is doing a retune necessary?

 

Unplugging rear o2 will throw a cel, you will notice if this works if cel stays away. You don't need new tune if you only remove rear o2.

 

ok great. thanks

 

I am not understanding how to do this. I Don’t have the option under the tephra to mess with the rear o2 in ecu flash. Spent all day trying to figure this out with help from someone else.

 

Using ROM ID 96530706

The following settings should allow you to edit what you need. This is based on Tephra v7.

 

I figured it out thanks. But still haven’t finished this job yet lol
