E38 / E67 Custom OS Beta release

[GMPX]

Ross, can you explain, why can't we change OS's freely like we could on LS1s?

There is several problems. GM have changed the structure of an important part of the ECM that stores the VIN, theft codes, misfire learning etc 4 times since 2006. That area is never written to by EFILive (or TechII) so if you update to an OS that does not use the same structure then when the ECM reboots it will corrupt itself. This is also why GM now have 4 part numbers for the E38 so dealers must order and use the correct one. On the ACDelco parts website it even states "(E38 NO-START) 8.10.X SW LVL" meaning it's only for 2010 models.

Second problem, I am certain that between years the CAN messages change on platforms. So lets say in 2006 the HVAC or Radio was using single wire CAN or VPW, then in the 2008 model everything went to CAN, using a 2008 OS it will be looking for all the expected CAN modules (which don't exist on a 2006).

Unfortunately the cars and the software is way more complex than the good old LS1 platforms were.

The safest bet is to just check on the CalID site and see what the latest OS is for a particular car and use that.

Cheers,
Ross

Update:
I've removed the files for the moment, we are updating them all to the same date to avoid confusion.
There will be E67 .calz files posted and a minor update to the 2010 E38 .calz files.
Expect everything to be posted within 24hrs of this post.

Cheers,
Ross

Downloaded and extracted the .zip file correctly, I get the proper .calz date of 12-3-09 when I open my 08 TBSS E67 file. OS is 12618164, Cal is 12618163. But when I go to the Upgrade OS tab, it is blank... Just checked it with the included 2009_Holden_E38.tun file in the My Docs\V7.5\Bins with OS 12624402, there is a COS for it also but it doesnt appear in the Upgrade tab.

Do you have the V2 plugged in when you start Tune? I added that in to the tutorial as a few people were getting caught out by that.
BTW, your OS is one of the ones that has been included in the E67 release.

Ah, I didnt. Brain fart. Works great now, too bad I dont have a nitrous kit on the SS to test this nifty feature with. :( And I saw that the 8164 OS is included, sweet! Pretty sure ALL 2008 TBSSs have this OS if they've been to a dealer somewhat recently, bet that makes your life easier huh?

Is there going to be an update for this for recent parameters that were added?

Thanks

Not in this thread, they will come out with the next release.

[Highlander]

are all these updates included in the dec 20 update? No need to redownload and recopy?

and.... what about some of the A/C tables I had requested?

If you need them desperately you could always add them in as a .cax
