Well hope that turns out better than what it sounded like
There really needs to be a T/S (trouble shooting) section so that anyone with similar problems can find help faster.

 

soon we will have an answer, soon!

 

Looking forward to that!

You guys are great!

 

any updates? anything that needs some more testing to help fix some of these codes ill be happy to help as much as i can. Just give me an idea of what your looking for when you have me test things.

 

So far, he's CEL-free.

Another couple of days + one more test and we'll likely call it a done deal.

Rich, maybe toss him the experimental stuff? I haven't had any CEL's, be nice to try on another vehicle with a different build to see different results.

On another note, I was brain storming before I slept and something came to mind.

With the shifts being much smoother with the tune, i was wondering does that mean less clutch pressure between shifts? If so, wouldn't that mean more rubbing and more wear and tear on the clutch disks? I could be wrong but, it was just a thought.

I don't yet know if the "experimental P0139" thing is even necessary... as the "traditional" P0139 disable was never actually tried in conjunction with the "ECU Options rear o2 disable" / P0140 tweaks.

Oh, and I just emailed you about some more testing. So we can confirm exactly that.


Regarding beta SST tuning, that's way way way off-topic.

sweet cant wait.
When i enable my rear O2 sensor i keep getting the stupid heater CELs but i think its becuase the sensor got messed up. i have a another new O2 sensor waiting to get installed becuase construction workers destroyed the road to my apartment and it got scraped up and i had to splice 2 of the wires and tape up another one so now i have to change it AGAIN. The old one will hold me off till the weekend. This time i have a bunch or convilated tubing im going to put on so that its protected and triple check how i install the new one so it cant get messed up again. Maybe when i change it the heater CELs will go away.

 

so i changed my rear o2 sensor this weekend and everything was great i even reinstalled my o2 spacer then turned my rear o2 sensor back on. cat monitoring is re-enabled and no CELs except the one code that has been haunting me. P0137 heater CEL...

****Update****
Changed the sensor before i left town and it didnt help... still get P0137

 

still running cel free? i cant test anything on my car as im out of town/USA for a little bit but hope that when i get back i can fix the issue with the heater codes.

 

What is confusing me is, you have a test pipe (ie. no cat) yet, you want your rear o2 sensor operational. The rear o2 sensor is ONLY for cat/emission readings, nothing else.

So, if you have the cat removed why bother working on having an operational o2 sensor and wasting time/money on it. Best bet is to disable it with ecu flash.

Richard posted on the forums in the GST thread on how to disable the o2 sensor for good. Disable it via ECU #2 and see if it still gives you the heater code.

I just want to help, figure out what you ultimate plan is.

i know it sounds silly right now but when i go home back to New Mexico i have to have a cat so im getting it ready and my emissions test is due soon. In north Dakota they dont have emissions but im not going to stay there for much longer. For along time i did have my rear o2 disabled but when i was looking into a few things figured id play around with the car and see if i can get it set up for the return home.
