I have good news to report. I did as advised and it all is working as it should. I had a feeling it was something I was doing wrong.

Thanks again everyone.

I will try this tonight. I still think it is something I am doing wrong, like this. That is why I love this forum. A second set of eyes can go a long way.

I will do as you recommend and report...

I will do. Sorry if it looks like I am getting over the top. I do not mean to come off like that.

I guess it does not look like something I left out. Which is what I figured it would be.

Anyone ? Help? We are still having this issue.

Here is the config I am using.

What config did you use? Post it so we can see what you are seeing. Do you have a WB on it as well?

I want to see what the STFT's are doing.

Do you have a log to show us? We will need that as well.

A little history on this PCM. It is an oddball config from GM so to speak. When I first hooked up to it with HP Tuners I was able to download it and I was able to license it and tune it. But our...

That is what i am trying to say.

I cannot find anyplace I missed that is causing this. I will try as you sugest and log the PE and fuel cell bits. I will post my results.

In the mean time if...

I thought that is what I did in .8.hpt, .8.hpl . The original tune had the STFT's enabled during Open Loop operation. I switched that setting to Disabled so that it would not adjust the fueling...

Help please

Tuning in open loop speed density but wanting it to run in non PE areas in closed loop speed density. So after tuning turned closed loop back on.

Final Boosted fine tuning we have not completed...

I tried it. It did not work.

When it enters Boost PE the commanded AFR is changing to the Desired AFR but the STFT's are not going to and holding at 0. It acts like the PCM is not going from...

I will try it this evening.

Thanks

Bill?

Anyone have any ideas?

Here is the last one

Ok this is the OS that did not have the 2barr enhancement option. HP Tuners got the oddball working for me.

Now that I am close to finishing the tune I set everything to let the STFT's and LTFT's...

Update...............


Have to give much thanks to the guys at HP Tuners. I sent the requested info in and they did look it over and provided a fix for it. I am now (and so can everyone else)...

I just sent the tune and the info log to support viu my email. Thanks for the help.

Here are the three tunes I am working with. The first is the original tune out of the truck. The second is the tune I tried to flash into it (6807) so I would have 2barr enhanced. It is the one that...

I went ahead and spent two more credits so I can continue working on this truck. That makes 3 2006 Silverado trucks licensed. How many do I have to do to unlock the 06 Silverado's? Is there a way I...

So as it stand, we still cannot change the OS to a 2 Barr. What are my other options?

We took the truck to the local dealer. They were very helpful and willing to do anything we wanted. The Tech is really into this kind of stuff. We had every tech on duty hanging around and excited to...

DO NOT FLASH THAT TUNE INTO YOUR PCM! Look at my post in this thread. It is NOT a good idea. Copy from it and paste to yours what you want but don't just simply flash the other tune in it.

What...
