2013 Regal GS, Auto

[Ju1ce]

Is the auto GS supported?
I'm thinking of buying a PCM from the junkyard and tuning the car.
If it is supported, are there any specific cars I can pull the PCM from to use?
Car-part.com gives me a ton of different options.

Thanks.

There is a 2012 in repository as well.

Thanks for the info, I had read on this board that the auto hadn't yet been supported. But that was a few months ago.

When you get to tuning it and the throttle body closes on you for boost, PLEASE tell me if you figured it out!

The throttle body closes for boost?
That doesn't really make any sense to me.
I do know that some cars with drive by wire have tq management in the form of closing the throttle body.

The transmission control module might not be supported, I'm not sure what tcm they use off the top of my head, that doesn't mean you can't tune the pcm at least though

I did not find a 13/14 in repository but there are a few 2012, the ones I found did have TCM support but that doesnt mean the 13/14 will if HPT has never had one yet.

[Bill@HPTuners]

The 2013 read I have has a T76 auto which is supported.
The 2014 read I have has an unknown tcm and only the pcm was read so I don't know if they are still using T76 or something different at this point

before anyone asks if I can post the files, no, they are customer files and not my property to post.

The '13 GS has the same OS as the supported '13 Verano T for engine, and I think for transmission as well.

Yes the throttle body closes a lot every time the actual boost becomes higher than the desired boost, there is a huge topic about this already elsewhere and I am trying to stir it up here as well because I am desperate for help. That is the reason I am buying HPTuners.

So anyone with any info on the tb closing is it a maf table or boost table, pretty sure it under the torque managment

Awesome thats what i've been looking for, Thanks

Just an update on this, issue has been completely solved and model is fully supported.

Can you do a full write to a donor PCM for these cars without issue?

[Boost]

It's been a long hot day for me here, I am not 100% sure I understand your question. I am convinced though you can install a new / different E39A into your car and write it to run perfect. I would also think you can "full flash" it - though I have not had the need to try.

[Ju1ce]

Yeah I'm trying to run another e39a 12655476 serv#12653998. For two reasons. One after I tune the car I can sell hpt and go back to stock at any time just by swapping pcm's. And two, in the off chance the car ever needs warranty work, I can pop the stock PCM in and they won't know it's tuned.

[Boost]

Should be able to do no problem. But confirm if you can.

[Ju1ce]

Will have the spare PCM here in a few days.
Guess we'll find out this weekend lol

[Ju1ce]

Does the T76 TCM log flash counts?

[Ju1ce]

In the middle of trying to figure this all out. I read the stock PCM and licensed it. Then I installed the spare PCM and did a full right to it after licensing that as well.

With the spare PCM and installed it still reads the old vin number and the car won't start although it will let me flash to the spare PCM.
