I read through darkmitsu's write-up on how to wire up the AEM UEGO for datalogging with Evoscan w/o the serial cable. At the end, he shows how to get rid of the CEL that is tripping now. The problem is is i don't see those tables in ECUflash. I have searched and searched, but I found nothing helpful.
Anybody know what to do or where to go?
Thanks

 

If you're running any of Tephra's roms there is an option to disable to rear O2

You can also do it through the periphery bits...what version of ecuflash are you running?

 

I'm running v2.7. That link you posted up kinda confused me. I apologize for the ignorance since I'm still getting familiar with all of this, but I'm not too sure what a Tephra rom is exactly. And also, I'm pretty sure that i have the latest version of ECUflash(v1.42), but the pic of the ECUflash tables towards the bottom of the thread has more tables than I do.

 

Is there any way I can Fix the CEL without resorting to a Tephra rom? I have been running the spacers in the 02 sensor bung (I believe it's referred to as the "mechanical fix") for a while with no CEL, but as soon as installed my AEM UEGO and hooked up Evoscan and ECUflash, it came back on. Thanks guys.

 

Someone correct me if I'm wrong, but I believe disabling ecu periphery4 (FEA) bit15 addresses that. (Change the value from 1 to 0)

 

thanks. someone else please chime in if you know, but for now i'm going to disconnect my battery to reset everything and change that periphery you mentioned. i'll keep you updated.

 

bump would like to know the answer as well , I searched around and found this here https://www.evolutionm.net/forums/5353216-post148.html

Haven't tried it yet, maybe 2mrw I will

 

I tried this the other day with no success. Anyone else have any ideas?

 

I used a resistor like in the first link, got a pack of them from radio shack for 1.99$ i think. there cheap either way.

This looks like an option for someone that wants to remove their rear 02 sensor completely. I don't have a reason to remove it, so i was planning on keeping it in there. Also, the above post includes links that suggest options involving alterations to your XML file. I'm having problems editing my XML. It keeps denying my access. This is the same reason i haven't been able to properly complete the install of the Tephra rom. I have been trying to find a way to do it, but I'm having difficulties. HELP!
