E38 / E67 Custom OS Beta release

Hi all,

Attached to this post are the files required to use our new custom OS's for the E38 & E67 ECM. This covers all E38 OS's supported in EFILive from 2006 - 2010 (all 39 of them)! and a select group of E67 OS's (TBSS, CTSV etc).

So what does this modification do?
By applying 12V to a spare input on the ECM it forces the ECM to believe the car is running 85% ethanol fuel, in doing so this allows the use of a whole range of fuel and spark tables already in the factory programs. We've also added a second Injector flow table in this mode to assist in alternate fuel situations where different injectors might be used.
These additional tables will assist tuners make the most of using alternate fuel types such as LPG / Propane, or for racing applications using Nitrous injection.
The E38 / E67 ECM's already offer amazing tuning functionality for a factory computer. From ready to go 2.5bar SD tuning (with EFILive’s Virtual VE Table technology) to variable camshaft control, even supercharger controls on the E67 this new enhancement from EFILive just puts the icing on the cake.

The files below are being released in Beta form, once they have been in use for a month or so without any issues we will release them with all new software updates. Keep checking back for updates prior to release.

Before you ask clause!!
No feature requests, these custom OS's have already proven in the field to be perfectly suited for the applications in mind.
Where do you get the ECM pins from? Sorry we don't know, we pinched some from an old harness, someone at a dealership might be able to shed some light on this.
Can V2 activate the Ethanol mode? No, that feature was removed due to the complexity of modification required to the OS.

So to get these new OS's on to your PC, look below for the files attached to this post and do the following:

Save the file "E38-E67 Custom OS Upgrade Tutorial.pdf" in to:
\Program Files\EFILive\V7.5\Doc\Tutorials
Next time you start the Tune Tool it will be accessible via the Help > Tutorial menu. This document is a work in progress at this stage, keep checking back for updates.

Save the file "gm_enhanced.prn" in to:
\Program Files\EFILive\V7.5\Configuration
This updated file is required so DMA PID's will work with the new COS's.
Black Box Logging has not had this update yet.

Download and extract the zip file "E38-E67_COS_03-Dec-2009.zip" in to:
\Program Files\EFILive\V7.5\Calibrations\
After these are extracted in to the correct folder the .calz files dates as shown in Tune should be v7.33, 03 December, 2009
** The Dec 3rd update includes the E67 .calz files and a minor change to the 2010 E38 COS files, please replace any existing .calz files with these ones. Please do not use any of the older versions of the .calz files for creating custom OS's, you must use new these ones. **

Have fun and please leave your feedback in this thread.

Cheers,
Ross

The E38 connectors are Delphi.

the two E38 have the following part No: (sorry the T42 connector is also listed..)

Part Number, Description,
13511426 "80 Way Gray 0.64 Sealed Female Connector Assembly",

15463921 "49 Way Black GT 280 Micro 64 Sealed Female Connector Assembly"

15499466 "73 Way Black 0.64 2.8 Sealed Female Connector Assembly"

the different pins are:
Terminal Tray

7116-4152-02/9
33467-0003/23
33467-0005/23
15339541/4


To make sure you got the right pins pls check on the Delphi webside :

http://connectors.delphi.com/dcsgdmcs/homepage.aspx

and try one of the connector part No in the search box. You will find all additional info then.
Delphi Germany was very helpful for me when I did my swap last year. They supported me with lots of free samples... just give it a try..

Thanks Harald, do you mind if I put this info in to the tutorial?

Interesting!

HERE's a link with lots of connector info...

no not at all, but give me a day or two and I will look it up in detail.

About what spare pins are we talking (connector no, pin no) so that I can determine the pin size, I remember there were two different pin sizes..

harald

Mike @ EFI Connection has the Pins & Connectors in stock for the E38...:D

Super cool, now I can have DD timing and at the flip of a switch a Race Tune Timing Table.

How come I can't find V7.5.6.99? I have build 88 running........perfect by the way!:grin:

Was it a beta update? Been slacking on beta stuff but want to fool with the COS stuff.

Thanks

Its in the information section, heres a link:
http://forum.efilive.com/showthread.php?t=12014

You'll be good to go with that, unless you want to deal with LBZ/LMM DSPs and the new E38 COS stuff. Have to grab the appropriate files from their respective threads.:cheers:

Howard, you might be ok with build 88. We've made some important changes to accommodate the 2010 models, build 88 has the important stuff, the beta version has more.
There should be no problems using these COS files with build 88 should you rather not update to beta tuning software.

Cheers,
Ross

As promised the detailed connector info of C1 and C2

I also have a .pdf (with 5MB too big to upload here) with all the connector pin descriptions. If anyone needs this just let me know I can email it.

Hey guys, all of the information that I have found was that the E38 ecm connectors were made by MOLEX? When you did your E38, did you actually use DELPHI connectors?

just copy the connector part No and paste them in the search box on the Delphi webpage... you will see the correct E38 connectors.

A few pics to show how the wire/terminal is added to the E38 body connector:


Body or J1/X1 Connector for E38 ECM. It is the 73 pin connector. Note the arrow to cavity 5. Most unused cavities have either a blue plug or a black plug that is molded as part of the connector. Cavity 5 has the molded in plug. The cavity is blocked with this plug.
Attachment 6722

E38/E67 .64 Series Terminal with wire
Attachment 6714

Flipside of connector - terminal side where it plugs in to ECM socket.
Attachment 6712

Small screwdriver is used to break the black molded in plug loose. Push on the edge of the plug alongside the cavity wall for best leverage. It should break loose without too much pressure if you push in the right place.
Attachment 6713

If your connector has the molded in black plugs, they need to be removed from the terminal area underneath the terminal seperator. Use a small screwdriver at each end of the seperator to leverage it out. Cable end:
Attachment 6715

Continued:

Leveraging the other end to the cable side out. The seperator needs a light push upward to unclip it at each end.
Attachment 6716

Terminal side view.
Attachment 6717

Look into cavity 5 for the molded in plug and remove it with a small tool. Though some connectors may have no plugs, and open seals, this is unlikely.
Attachment 6718

Terminal on the way in to the right cavity. Make sure it is oriented the right way around. There is an open section in the terminal which needs to engage a locking tang once pushed in.
Attachment 6720

Terminal all the way home on the connector side. Note a "click" when it is in the right place as the tang clicks in to the terminal.
Attachment 6724

Connector with terminal seperator re-installed. Only goes one way, with different sized tongues on each end, and the ground terminal.
Attachment 6725

E67 uses same connectors, but they only plug into an E67. Process is the same.

If you are in the land downunder, and cant find any E38/E67 terminals, we have single wires with terminals crimped on. PM me.

Trust this helps y'all.

Very insteresting update ! I wish all that info was available when I
was messing with that 07 Escalade to run on E85 about 2 years ago.

Thats a cool step by step..:D

Nice job!

Howard

If anyone wants to save the above information or print it out, I have created a PDF for the above diagrams and instructions.

Nice thread, contains all the needed material...:cheers:... stickied.

Awesome Ian, thanks, I'll add them in to the tutorial.

You're all welcome guys. Thanks for the positive comments. Glad you like them and hope they help get this up and running. :) Great addition and some interesting possibilities come to mind. :)

I've put Ian's guide in to the 'official' tutorial, just re-download it from the link in my original post.

Thank you ROSS>.. JUST IN TIME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!

E67 custom OS to follow soon? This is just what I need for N2O on the TBSS!

Sorry, I should have given you a heads up it was coming for your 2006 after saying no a few months back.

Yeah, E67 will be done before the Christmas break. Not sure ALL E67 OS's will be done, there is even more of them than the E38, but any OS used by the GenIV will be done, unless grandpa wants nitrous on he's DeVille too then Northstar will be covered as well. Might be a good wind down to Christmas project for me to get them all done. :grin:

Cheers,
Ross

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

Pretty sure its because different platforms use different pins for different things. For example, I know on the E67 OS used in the TBSS there are significant wiring differences between it and the E67 OS used in the CTS-V. Different pins for injector outputs, cam sensors, grounds, etc.

From what Ive gathered over the years most (if not all) LS1 PCMs used the same outputs for all OSs, the different OSs contain information like truck vs car, f body vs y body, lean cruise down under, etc. This seems right in my head, can anyone else verify?

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

Updates posted.

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? :D

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.

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
