Let me know whom you are talking with in support at SCT and i will try to get them to help out quicker.
Questions
In stock mode do codes come up?
Read strategy of truck with device in stock mode , Let me know what that is?
Is the truck not running correctly? in stock form and how about tuned form?
The P1000 code is turned off in tune should not be able to pull it? Can you pull this code with SCT device or AE?

I have a support e-mail in to SCT but have not heard from anyone yet... Thought I would give them until Monday and then give a call. I feel like its one of those situations that its not a popular vehicle and everything is technically working, so people that are willing to jump in and figure it out are going to be a little sparce. Would be pretty cool if I'm wrong
Truck is running fine- Always ran well in stock form and the tunes are working good as well. The tow tune is definitely different than stock!
Like it ! No problems, other than AE scan tool codes showing. No codes show up with SCT tuner. Not even the P1000. I know its not really a problem... But its not right either. Especially if I do have a cluster issue in the future and need to use AE to troubleshoot. How to decifer a bunch of bogus codes ya know.I'll get the strategy in stock mode, and see if I can then clear codes. Cannot clear with AE and tune installed...

If it's a programming issue caused by something within the tune or the delivery of the tune, then it won't go away til the truck is reverted back to stock. If the codes are still there, then it's something to do with AE. Either something within connection options isn't setup right or something hinky with the software.
Do you have the latest software? 8.2 I believe it is. 8.1 did have some connectivity issues with it.

If you can clear them(or they clear themselves) after the tune is taking out, then that's just another nail in the coffin of "it's the SCT". AE is different from the IDS software is that it doesn't matter if a tune is in there or not, it should be able to clear codes, if there isn't always something there to send a signal to trip the code.

Strategy of stock tune: MZAH0A8* (Has asterisk looking character at end)
Stock tune with AE scan tool connected, had same error codes...U1058, U1059, U1262, U1027.
Codes DID clear when asked (Unlike with tune installed). Re-Scan for codes only shows the P1000 like stock always has.
Re-Load 89 Towing tune... Sct shows no pending codes.
AE re-scan shows same error codes as above.
Looks to be SCT...

Yep, it does look the way. I'm wondering if SCT throws more codes then people realize, because not everyone has AE, equilivant, or better to scan all the module codes.
It might just be nature of the beast, I don't know. I don't have SCT on my truck anymore to test that theory.

I think so too- Seems most people just have basic code readers, or just use tuners with the code readers built in. But it sounds like they only show powertrain codes. Hope SCT will give a shot at addressing this-

I have a question, given the first code, a U1058
Do you have a trans temp gauge? Is it reading correctly? The second code, a U1059 is the transmission range switch not reading correctly. Which means the PCM wouldn't even know the truck is in gear, and yet, it drives correctly.
If so, sounds a lot like those codes aren't real.
In computer programming terms, the SCT has moved something, and the AE is reading the wrong spot in memory. Neither is at fault, just an incompatibility. Just a theory.

Only trans. temp gauge I have right now is the stock one... However, its reading just fine. Not sure if the dealer scanner would show the same. Really dont want to pay to find out just yet. Its a thought though...
Did just notice something about trans temp and tunes... Just pulled a small trailer with 89 Tow tune and it wouldnt shift into OD until it was well into operating temp zone of factory gauge. With the 89 Performance, it shifts into OD as soon as it comes off of the cold mark like it did with stock tune. Not sure if this is part of Tow strategy? Mike?

Mike- So why the temp delay shifting into OD? Not complaining, just wanting to learn.
It's frustrating trying to figure things out on these tuners and scan tools. We buy something thinking it will work, or hoping it will because it seems like there is so much junk out there. And now I should go spend more money trying to figure this out? And then what? Still try and prove to someone at some company that they have an issue with their product. They wont even return communication that they have set up. Somehow that doesnt seem right to me.
Time for rum and coke.

If the dealership is using their IDS software, then more then likely it won't be able to communicate with the truck with the tune installed. Now if they are using PT-DIAG or equilivant, that might be a different story.
