View Full Version : E38 TIS Programming warning

Hi all,

We just wanted to make people aware that EFILive support is now seeing a number of people who have had problems with E38's after reflashing them with TIS.

To narrow it down, the issue appears to be when the ECM is updated to a 2009 OS from a previous release.
The sort of issues that are being reported are -


ECM becomes locked (can't read or flash) - Use key $E405 if this happens.
ECM looses serial number (lost license data)
VIN becomes scrambled

To make matters worse sometimes the ECM cannot be recovered from this state and a new ECM must be purchased, it really comes down to luck as to what level of corruption occurs.
It may have something to do with the ECM version, there appears to be two part numbers for the E38:
2006 - 2007 = 12597121
2008 - 2009 = 12612384
We think it is when a 12597121 ECM is updated to 2009 then problems occur, it's hard to say at this stage.
The final issue is that the vehicle may actually continue to operate normally even after the corruption which makes the decision of buying a new ECM difficult.

So far we have had no reports of similar problems when using EFILive for programming, but unfortunately people need to use TIS sometimes to put a stock tune back in to a vehicle if they weren't the original tuner or to update to the latest releases from GM.

Please keep in mind that this is not an EFILive issue, therefore EFILive will not issue free replacement licenses for corrupted / replacement ECM's.

At this stage there had been no reports of similar problems with the E67, but that doesn't mean there is no problem - EDIT: Apparently E67's are suffering the same problem too.

Cheers,
Ross

Ross,

Interesting info. I assume that if we did a TIS flash, as long as we use the "current" update as provided by TIS then we should experience this issue. Is this just if you try stuffing the new OS in the earlier PCM?

I think so. If you had a 2008 vehicle with an old 2008 OS and you wanted to update it to the latest 2008 OS on TIS then things will probably be fine.
It is when you try to do the big jump it might fall over.

I hope I'm not overstepping my bounds here but if any of you are in a pickle I've got a few cases of NEW E38's with Serv #12612384 (along with 09 E67's E37's and T42s ect..) in stock on my website.

Heheh yeah I've typically got anywhere from 10-20 cases of ECM's most of the time @12 units per case. Also I know alot of you are outside the us and the shipping cost VIA UPS is pretty extreme, email me and i'll get you a USPS quote which is normally very reasonable.

Looks like GM has planted an exploding easter egg in the E38 :shock:.

To paraphrase 2001 A Space Odyssey....."you can do anything you like to a 2008 and earlier tune, just dont touch the 2009's". :doh2:

From what I have seen this morning doing some experimentation, do not update any 2007/2008 E38's to a 2009 OS using TIS, you are going to end up with a messed up ECM.
I have performed multiple flashes of 2007 OS's without a hitch, as soon as TIS programmed in OS 12628982 I lost all the ECM info and it was locked.
FYI, the 2009 OS's are - 12617175, 12628982, 12628983, 12628990, 12630501.
As I mentioned in a previous post, there was a part number change for the 2008+ E38, this might have something to do with it.
Interestingly, they now have the warning below come up when programming 2009 ECM's..........it would be nice to know what the 'set-up' is (maybe it's crossed your fingers).

Chuck, TIS has of course never been 100% reliable with programming, early Duramax's are bad, still are, they have a similar issue to this one where all the ECM serial, VIN etc is wiped after TIS programmed them. Still, I am not criticising it, I feel their pain!

One more thing to note, the location of the VIN changed in 2008, so if you update a 2007 OS to 2008 you will find the VIN is missing the first 4 digits.

Ross

Nope, ECM is locked.
However, Jesse (Wait4me) told me this morning that when he logged on to SPS it did an update, since then he's flashed a few 2006's to 2009 OS's and they were ok, so maybe they fixed it up pretty quick.

Interesting. I was unaware of the ability to even flash an 08+ OS into an 07, every attempt I have made ends up with TIS timing out on the flash portion of the process with no work done. Then again, haven't tried in about 6 months, just flash 08+ to a 2384 ECM and 07 to 7121.

Unheard of! I have yet to have a successful 99-00 PCM flash with TIS complete successfully... and yet I keep on trying for some reason with hopes of the process working properly the next time. :shock:

My Experience with TIS has been like everyone else's. Has its hi's n lows...

Mainly it is just figuring out what settings you need before you connect to a PCM/ECU and flash - once setup right the tune goes in straight away no problem

I have tried many combinations and now can flash tunes into LS1 non fbw and LS1 fbw PCM's and E38's (still havent had/tried an E40) ... This is both Chev and Holden tunes... the Holden pose to be the trickier ones... what GM were thinking when they built the database in TIS i dont know.

GMPX

The trick is to always select "Replace and Reprogram", then you just supply a valid VIN for what you need and it should all happen regardless of what is currently in the ECM. Mind you, it would appear by doing this you are also bypassing some checks that TIS has in place to make sure you don't program the incorrect things in!
I don't critisise TIS too harshly, it would be a total nightmare trying to track exactly what each vehicle requires. I can certainly understand how mistakes can sometimes happen. If it wasn't there we would all be stuck!!

I always do a replace and reprogram but that doesnt seem to help me when i try and program an E38 if i say it is a holden already.. It comes back with cant find ECU please make sure switched on blah blah blah.....

have to trick it etc... then it say must be a new ECU etc.....

also when going from a 99 model LS1 PCM and upgrading the OS can be tricky.. cant seem to just jump right in.

JUST USE EFI LIVE...

For most of the time...TIS FAILS...ESPECIALLY, when your internet connection is not fast...Not sure why cause the files are cached on your computer.

Anyway....When updating E40s and E38s with new OSs, use your head and DON'T USE ONLINE TIS. USE EFI LIVE for OS changes whenever possible on E40 and E38 cars. TIS SUCKS.

I think the TIS subscription on DVD is better and more reliable....BUT, the online TIS BLOWS...Especially when the internet varies.

LS1 pcms usually die and E40s always suck.

Early E38s have caused problems and sometimes die, and occasionally HPT will make them talk again.

I've seen several T43s die in the middle of a TIS flash and TIS or EFI LIVE will bring them back to life.

I had a T43 die on a TIS flash twice in Chicago the other day...It took me 2 hours to BOMBARD it with TIS, HPT, and EFI LIVE flash attempts to revive her....

Lucky for me, the combo of FLASH ATTEMPTS was kinda like a defribliator bringing a PCM back to life. Not sure why..But, the customer was happy.

To date....I've never roasted a T43 and I play with them a bunch.

Can't say that for LS1, E40, and E38's. I always cringe and hold my breath when I do an OS change.:bad:

you cant use EFI Live when you have a brand new E38 and flashing to a Holden tune.... Do that and you will have alot of mysterious throttle problems...

TIS is needed and I have the DVD's not the online subscription.. wasnt going to pay a $1000 to flash one PCM then come day one of the 2nd year have to resubscribe to do another :) :) DVD will always be there....

only ever need it to put a base tune in the ECU.. then flash in the changes later

What do you mean by kill off??? (bit hard when it is a protocol - not a device that you choose to program with)

the MDI has been out for a while... and there are a fair few more devices along the same line out/coming out very shortly.. the mongoose is an awesome piece of hardware and they have priced it well (but doing so makes it only able to do certain protocols) . If you need to do all the protocols they have the cardaq but the price is also a lot more...

I am going to prob get rid of the mongoose and go with one of the newer all in one devices soon once a mate has tested it a bit more as they will be able to also program F...F...F... FORD (there said it)

Hi Ross,

Sounds interesting, I have never flashed a later os in my vehicle only the current one. My car's speedo ceased working after a reflash with ign off with the previous software(efilive) release. Was not related to GM software/hardware compatability. So in my case am I entitled to a replacement pcm? As it appears my pcm has been damaged from efilive software using its original operating system.

GM currently has to allow devices other than TechII, they don't just appear in the options menu by magic, if they wanted everyone to use the MDI then they simply drop support for all the hardware in TIS2WEB and only give the MDI option.

I am not 100% comfortable with the wireless unless the MDI can buffer the entire contents of the flash before starting.

In TIS you add the devices yourself to the application (thats how they appear magically) - not because of GM. Secondly TIS uses different protocols to talk to the different Hardware The Standard that uses this is J2534. MDI , Mongoose Cardaq are all devices using this standard . GM wouldnt remove it as they are cutting off the own hardware sources/devices.

Note: - I am talking about TIS DVD not TIS2WEB but i am sure that one of the options would be J2534 Pass Thru. (which the tech 2 can actually act as well).

What is your Email address so I can search? I don't recall anything about this or wanting a free ECM, did you send it to me direct or support? Maybe it was spammed by a filter, hotmail accounts etc are usually killed by our filter.
I can fix 99% of ECM problems, I would be happy to assist, shoot me a PM, or is there a thread where you discussed this?
I'm still not sure how on earth programming an ECM with the IGN off can even be done yet alone cause a speedo to stop working, that was the part I meant 'Are you serious?' , sorry for the confusion.

Google allows one to revile some interesting things about what people say in public. I was not aware that EFILive killed so many E38's for you (5 wasn't it?)
I've searched on here for a post from you regarding how to recover failed flashes, found none, I asked support if they heard anything, no.
Dale, I've never spoken to you on the phone or via Email about any issues you have had, in fact I didn't even know you were using EFILive, I figured since your forum banners elsewhere have the HPT logo on them then you wouldn't have EFILive.
You are probably not aware of the amount of PCM's I see pass my bench for recovery and unlocking from workshops, from what I see with most of the errors, the term you used 'trusty HPT cable' can't be taken as gospel.
Hey I'm glad you gave EFILive a go for the VE SD tuning, but before you throw it in the corner and tell the world it doesn't work maybe put your hand up for some advice from us first.

i actually brought my v2 cable from Dan at Chip master around 12 months back..

i did actually email support at the time when it first happened... i got nothing of use back other than "it has been a few hours did you get it sorted" to which i replied yes i did get it sorted i did this... and explained what i did, not my fault there is nothing on the forum about it....

im only starting facts here. i have never had a problem flashing any PCM with my HPT cable, weather it is a LS1, E40 or E38 they have always worked perfectly fine..

im not going to get into a HPT ve EFI bashing session, only stating facts, efi live has done all i have asked of it with a few little issues...

EFI LIVE killing E38s??? Very strange. I'm doubtful that almost anyone out there has flashed as many E38s as me with Efi Live....With NO problems.

I've flashed quite a few E38s where the vehicle power dropped off, customers started opening power windows and moving power seats, my laptop battery died:angel_innocent:, and where I even (accidentally) pulled the usb from flashscan while flashing E38s.....and never had a failure, lost a fuel guage, or ANY other issue.

To the contrary....I rarely if ever use TIS to update E38s cause it sucks. It fails more often that I'd care to say and seems to me (even though the files are cached) that when the internet or wireless signal is weak...It always fails and I've lost way more controllers than I'd care to think about.

In fact, I actually use EFI LIVE to recover most failed E38 TIS flashes...and in a pinch...Hammering the pcm with HPT over and over sometimes works as a last resort.

Some of the early vintage E38s just fail if you look at them too long. It has nothing to do with anything. It just happens.

I have to honestly say...Something else must be going on or maybe you just got a bad pcm cause....

If I ain't killed an E38 with Live.....I don't think it's possible.:bangin:

EFI LIVE killing E38s??? Very strange. I'm doubtful that almost anyone out there has flashed as many E38s as me with Efi Live....With NO problems.

Dale, the reason I sparked up about your comments is that what Chuck has said is about par with what most people tell us. I'm not saying you didn't have problems with your EFILive set-up, obviously you did, however, for only your second post on this forum to be how wonderful HPT works for you was a little out of order.

as i have stated before TIS i have lots of problems with... but have never rendered a PCM/ECU useless....

just finding it very hard to believe that GM have done what is said... as they have locked them selves out if the seed/key changed


i would find it more believable that while flashing a PCM there was an error cause by communication problems...

After I'm done I attempt a regular cal flash and it says "bootloader rejected" like it's locked.

If I press the ALT KEYS button, it seems to work on the second try...or the 3rd maybe?

After flashing it, I plug in to check/chenge the vin # and there is GARBAGE in the VIN....

Now, these pcms came in NEW with the red light flashing on the bench harness....They have never been touched.....but, they are locked after flashing them with efi live now....WTF?

Been dealing with this issue via Email too.
From what I can see the problem appears to be a change GM made in ALL 2009 OS's. If the ECM has a 2009 OS loaded from factory then you can only put another 2009 OS over it. Any attempt using EFILive or TIS to reflash a pre 2009 OS will result in a corrupted ECM.
Same goes for any 2006-2008 E38, put a 2009 OS in to that using EFILive or TIS and it will end up corrupted.
This probably explains why the 2009 E38's have a new part number from the 2006-2008's as they come with the correct 2009 base program.

So for the 2009's, at the moment don't attempt to lock the ECM with EFILive either, knowing what the problem is with the 2009 ECM it might result in a corrupted ECM. I will be able to fix that easy enough in an update.
The swapping between the 09 and earlier OS's might be a little more of a challenge. But we will be looking in to how this can be done.

So, in conclusion I don't feel the problem lies directly with TIS (or EFILive), it's the change GM made to the 2009 OS's that basically makes them incompatible with earlier OS's.

Ross

Actually, it's nothing to do with the bootblock in the ECM nor anything actually written specifically to the 2009 OS's, the 2009's just have some data structured different to the earlier ones that when you get the mismatch it causes the problems you see.
I don't really want to give too much away because it will be a nice fix to have in our software when it's cured. But it now makes sense as to why GM had the new part number assigned.


Can we have a "ROSS from EFI LIVE OFFICIAL E38 INTERCHANGE GUIDE"???:angel_innocent:
A provied 'as is' guide, sure. But, I'm away from my main office PC at the moment with all my E38 files so I can't construct anything until next week. The hard part is, some 2009 cars (Z06 as an example) are not running true 2009 OS's, yet the LS3 is!, so you can really base it on the model year of the vehicle. But I will make this list up next chance I get.

Howard, the 2009 Z06 is still running a 2008 based OS, not 2009 which is why any of the earlier ECM's would have worked fine. As I said above, the LS3 is running a true 2009 OS.

From a hardware perspective the 09 Throttle bodies on Vettes are quite different mechanically and electrically from the <09s. The 09 TBs can not be used to replace the previous 90 mm version for 05>08. Could it be that the OS is rejecting the TPS change?
The TBs look similair but are not. New part#, orientation and TPS best I can tell.

The plugs are the same but I know if you just swap a working 08 for the 09 it will not work. Throws a TPS code and freezes. The physical differences are confusing. Looks like the 09 is designed to be flipped. If in the same orientation the 09 blade movement is reversed.

Bruce,

Anyway, I've come to the conclusion, and I may be *way* wrong here, the reason the '09 TB will not work on the '08 vehicles, and vice versa, is that the ETC Area scalar needs to be changed inside the calibration. The '05-'08 C6s (and '05-'06 GTOs) had "4725.0000" as a factory value, and the '09 vehicles have "5636.0000". Maybe Ross can answer this (if it hasn't been already)?


Ross,

Speaking of, I'm in the process of obtaining an '09 processor with '09 LS3 calibration and installing it onto my '08 Z06. Why am I doing this? It's obvious if the car is going to be forced induction: 15k Hz MAF range WITH 127 #/hr IFR range (the IFR being key, so no more scaling down airflow values). I'm fairly sure everything will work properly once I make the necessary changes on the '09 LS3 calibration (basically copy/paste over my '08 Z06 parameters), at least I hope it does. Your thoughts on this, and the TB info above?

Thanks in advance!

GMPX
May 20th, 2009, 10:24 AM
RWTD, I don't think it will work.
You will need to get some sort of confirmation on the differences between the 08 and 09 pedal and throttle, if they are different then you will need to swap them in too.
I did look at changing the 2006 - 2008 ECM code to allow the larger injectors, but it's a mammoth task and probably won't happen.

Thanks, that gives me hope. It sounds as if you're assuming the same as me, the '09 LS3 pcm just might run any '06-'08 LS2/LS3/LS7 (provided one swaps in the '09 pedal/throttle assemblies, if they are needed). Is that way I saw? ;)

I hear ya on the IFR limitation issue. I know it's a monumental task at changing tons of code to allow for such.

All zero's, it isn't really fixed, it seems fixed, but it's not. I don't think EFILive will be able to get that one sorted for you.
There is also every chance that the Ign cycles counter before locking is not at zero, so there is currently no seed/key active, if the data is corrupted and that hits zero it will become locked.
