edcmat-l1 can remotely tune it better than most in person tuners.

Running means running the test or checking for a problem. It doesn't mean that the DTC is being set. The next line is what it has to see to set it.

Gen 3 can only handle so many channels at one time.

It would be a lot easier on you and everyone trying to help to just stay with one thread, at least until something drastic changes. Keeps you from having to explain everything multiple times and...

You are half way to the instructions given in the other post you made. Now the log half.

They are universal, even credits are now universal. It sounds like he is talking about the credits he used which doesn't matter since they are locked to his vin number if he used them.

My bet is he doesn't have HPT.

I’m pointing out the closed loop with trims Tuning suggestion not the maf.

- then turn the MAF on and tune the MAF (afr err)
- re-enable closed loop



Need to put it back in closed loop and use your fuel trims to dial it in.

A current version of your tune and a log of the problem is pretty much required every time. But making a new thread for every problem isn't. It would save you time explaining things to just add to...

If I had paid any attention to what forum you had posted in, I would have also told you that you would get more help if you posted in the correct forum. I'm not sure why people think that this is...

Log and tune needs to be added to have a chance for any help.

Screen shot shows as "permanent" (only).

Since that is a permanent code, it may have to see some drive cycles to clear? At least enough that it has a chance to rerun the test.

Why?

As always, tune and log needs to be posted.

Why was the new E67 replaced if it was running fine? I understand they have issues, but I'm wondering if you have the full story.

Judging by some of his other post, this is a swap vehicle.

I use “WB EQ Ratio Bank 1” (not SAE). They may have renamed it or the earlier post may have just used a nickname.

Well you still haven’t actually named a vehicle but maybe it’s just GM that gives good details on what is going on for codes.

You sometimes have to pay money to get the hood info. Most oems have some sort off subscription service to get to the model specific service manuals. But I don’t know if that is universal.

It no longer has the attached file but you can add the needed channels manually from the screen shots.

I would probably check a new OEM harness for correct connections before I installed it. I don't know that I would trust any of them.

Post the log.

If it was me though, I would get the wiring diagram for my donor ECM and check every connection, both for where it lands and for proper connection.
