also i dont know if this is related but the security light now comes on some times and the truck wont start, just cranks forever...

also if i do fix this problem will i need another license?

The 000000000000 serial number problems was present in a now seriously old (we're talking late 2006) software release.

What version of the software are you running now? The latest release is 7.5.5 Build 83. If you are running a version earlier that 7.5.5 Build 72 then you must upgrade. The latest full download is here: http://www.efilive.com/index.php?option=com_content&view=article&id=48&Itemid=124. Then follow the instructions below the link to update to Build 83.

You must be running a version prior to 7.5.5 Build 72 you will need to uninstall all existing EFILive software and drivers. Before uninstalling please copy your ‘C:\Program Files\EFILive’ and ‘Documents\EFILive’ folders as a backup.

Once the new software is installed the latest drivers are in the ‘C:\Program Files\EFILive\Drivers\EFILive’ folder.

Can you also please send a screenshot of the 'Help->FlashScan V1 PCM Licnesing' screen from the Tune Tool with your FlashScan connected to your PC to support@efilive.com (me)?

i had a battery error when i first went to flash it. it errored out before it started flashing. so i drove it to work (30 min drive) and flashed it at work then these problems started..

i have since put a new battery in the truck as the old one was 6 yrs old. it now seems that the key on voltage is about 13v where as before it was about 11.5 i have re flashed with the new battery 3x now with no avail..

also the computer i am running efi live on was updated last night and it still didn't have a serial after a full flash. i didn't however update the flashscan driver as i didn't know we needed to.

i will post the screenshot when i get home from work. thanks

i flashed it again today and same problem. also it has a vin in the file but when read or scanned there is no vin.

i was going to flash the stock file back to the computer but afraid that if it takes the file and fixes the problem it may cost me a license?

sent the blx files off

May 19th, 2009, 02:08 AM

still no reply form anyone at efi live. i have sent off the requested info 4 weeks ago...

today i reflashed the original file and it is showing the same symptoms, it wont allow me to do a quick flash only a full flash.

do i need to replace the pcm? if so can the credit be transfered to the new pcm?

And you're seeing:
PCM serial number goes to zero
VIN goes to zero
PCM now accepts only full flash
Vehicle won't start now

akafred

May 19th, 2009, 04:13 AM

when flashing it comes up blank serial number and will only do full flash.

after flashing if you do a read it comes up blank vin

truck wont run with vats enabled.

when i did a full flash using the original dump my truck wouldnt start. i had to full flash agian with vats set to none in order to get my truck to start.

The latest update to the V7.5 software (i.e. build 86) has a PCM recovery option for LS1 controllers. I'm assuming you have an LS1.

It requires that you do a full flash using a known, good *.tun file.

If you lose a license we will replace it free of charge.

still havent fixed this yet, i am getting these codes coming up now. the crank one was a easy solve just did the crank relearn the rest i dont really know how to fix...

alos i have done a normal full flash with the latest version, is that all that is to it or is there a special menu for recovery flash?

There should be a checkbox called "recovery" or something like that. Make sure it is checked during the full flash.

Thanks for offering to help out Jesse.
Akafred, I think that would be your best option to recover the PCM.

One last thing to try is to specify an unlock key of $00FF (same as the seed) before starting the full flash recovery.

Can you also send me the blx file that is created when you tried to reflash the controller.

Hey Paul,

A while back I almost loaded a custom operating system by accident. My son was looking at them when I was working on my car and did not notice until the last second that my tune was not the one that was ready to load.
I noticed that they all have a vin of 00000000000000. I had a nightmare about that almost happening for a few weeks as that could have toasted the PCM or made it very difficult if not impossible to find the seed or vin within what is left of the PCMs RAM/ROM etc etc... It seems like the steps you are suggesting is the same thing.
So is this what could happen if that was done.
I am not saying this is what happened here but it seems so similar.
Respectfully,

In normal full flash mode the EFILive software goes to great lengths to NOT reflash any vehicle specific data from the *.tun file into the PCM. Instead it saves all the vehicle specific info, erases the PCM, reprograms the PCM from the *.tun file substituting in the previously saved vehicle specific values. If the PCM already had bad vehicle specific data then a full flash would never be able to "correct" it.

So we added a new "recover" option.

The recover option bypasses the saving/restoring of vehicle specific data. When you do a "recover" EFILive copies the vehicle specific data from the *.tun file into the PCM. That means you need a *.tun file that has good vehicle specific data (VIN, BCC etc) when you do the recovery. Usually the original saved stock *.tun file is the best one to use in that case.

Even in recovery mode, EFILive will not copy the seed/key from the *.tun file. Instead it substitutes a pre-computed good seed/key pair. So the PCM will never be accidentally locked during a recovery process.

Regards
Paul

No 1998 files should show a vin number from the read in the software. To see if your vin is still there, which it is you need to just click on the chip at the top of the software and select your controller type and then hit "get info" You Vin should be there.

Thank you Paul,

I sounds like you have either found our programed a back door to the PCM.
I guess it is all hacking in a way but a great safe guard none the less and is appreciated very much. What if it was just the normal re_calibration (not the full re-flash). Once I had my wife in my car when I was flashing a small Calibration adjustment (not a full re-flash). During the process she opened my glove box and somehow the PCM was loaded with 19980100 instead of 19980200. (This seemed to be impossible but yet it did happen) The correct tune and OS was the only one opened and could have been loaded(I had never even looked at or opened a 19980100 prior to that). But the PCM still interpreted the *.tun as 19980100 and in fact that was loaded. Was that because of the use of a circuit during the re calibration. I have always been very careful to double check what I am loading and not to touch anything in the car and make sure the car has finished all of its key on processes prior to calibration or re-flashing, but in that one case with the opened gloved box and the light in the box turning on affected what the PCM was doing. This had made me wonder if there was a short or something left on, what would happen to cars with an electrical issue. Also if a car does have an unknown electrical issue it seemed several things could happen that could be serious. It was a frustrating problem as we were in a bit of a rain storm and did take around an hour to repair the weird calibration/OS switch and an unknown vin. (I used that same tune to do a full re-flash so it was not the *.tun) I does seem possible that if the right calibration for the custom OS were merged due to an unknown or accidental electrical operation like turning on a light or short could cause a vin 000000 during the loading process. Unlikely but not impossible?
Please let me know. Since that time I have been wary of cars that could have a short.
Thank you,

Since the 97/98 PCMs do not have a usable identifier to determine the difference between 1997 and 1998, the VIN is used to make that identification. If the VIN is damaged then EFILive will probably not determine correctly whether it is 1997 or 1998.

Why the VIN went to 0's is unclear. During a calibration only reflash the memory that holds the VIN is not erased or re-written by EFILive.

Paul

Send me the computer with your vin number and an original read of your computer and i will replace the ecm for free. Just make sure to print this thread and stick it in the box.

my shipping info is on my website.

Perhaps this offer of 6 months ago might be a good option then?

If you do go this way Jesse can confirm a PCM swap has occurred and we will replace the license for you.

December 31st, 2009, 09:35 AM

i pmed him 4 months ago with no response.. also i cant really have the truck down for a 2 weeks to a month while shipping pcms to and from the states..

you make it seem like this is a 8month scam to get a free licence. in reality efi live hasn't been working and i have pretty much given up, last week i acquired a new pcm and would like to be once again able to tune my truck.

so i already have a replacement pcm all i need is licence for it. if need be i will ship the fried one somewhere to verify its fried..

Tordne

December 31st, 2009, 09:48 AM

i still don't have this sorted out. i want to put electric fans on my truck and without being able to flash the controller i am pretty much screwed..

can i cancel the licencing on this pcm and transfer it to another pcm?

i have a 03 pcm sitting here that i could use but i am out of licences.

The licensed controllers cannot be released within the FlashScan device. If you purchase a PCM license from our online store (http://www.efilive.com/index.php?page=shop.product_details&flypage=flypage_EFILive.tpl&product_id=20&category_id=13&option=com_virtuemart&Itemid=56) and supply a correct serial number and auth code (as described http://www.efilive.com/index.php?option=com_content&view=article&id=110&Itemid=120) you could have a new license generally within 10 minutes.

so i have my 100$ licence that is locked to my pcm , replacement 100$ pcm, and another 100$ licence and i will be back up and running?

300$ to tune one truck... sounds affordable.

also if waitfrome replaces the pcm i will still need a new liscence to flash it, how am i any further off?

also i need this truck to get to work, i cant ship the pcm to the states and wait for it to come back, this will be 2 weeks minimum turn around.

so seing as you are unwilling to replace the lost liscence what else can i try to get this to work?

If you lose a license we will replace it free of charge.

You seem to have an expectation that we are trying to rip you off, which is not the case.

One of our resellers kindly offered to replace the PCM for you some months ago. I have no idea where you are physically located as it doesn't say in your profile. A large majority of our customers are based in the USA, so incorrect assumption on my part perhaps.

I don't think there is really anything else to try. If all the guidance given by Blacky above has not helped then the PCM replacement is probably your best next step, especially if you have one sitting there.

We have people away over the Christmas and New Year period (naturally) and it is a public long weekend down here now. Our office does not open again until Tuesday local time (your Monday).

So if you want to get up and running quickly purchasing a license, which will be automatically fulfilled, is probably your best option. Yes it is going to cost US$99. When our office is open again we can probably credit you back the US$99, or provide an additional license as a replacement.

akafred

December 31st, 2009, 01:15 PM

I am located in Canada, the reason I never took waitforme up on is his offer is because it would cost about 50$ total shipping both ways, also if the paper work isn’t filed properly there would be extra brokerage fees ect, he also never responded to my pm trying to get more details, and at the time the truck was working decent and I didn’t have all the parts to do the e fans.

Seeing as I have a 03 pcm from a 5.3 4l60 I assume that if I flash my 6.0l 4l80 file on to it all should be ok

is there anywhere i can send my file to verify that it didnt corrupt my pcm? i would hate to have this happen again.

Tordne

i will swap pcm's tomorrow, i will verify that it can be read, if so i purchase a licence and try to flash my stock file to it.

if i have to start from scratch would i be better off just flashing the appropriate custom os to it ? seems like it may be useful in reducing fuel consumption slightly, and probably less likely to be corrupt..

Tordne

December 31st, 2009, 04:54 PM

I full flashed the tune you emailed fine, and read it out to verify. You could of course flash in the COS3 OS (04072903) and then just cal flash in the file you sent.

akafred

January 1st, 2010, 12:35 PM

put the new computer in and it read no problem, will try to flash it tomorrow.

12585950 is my os

12592618 is on the new computer

will this take my os?

Tordne

January 1st, 2010, 03:49 PM

The new PCM is still a 1MB LS1 controller so you can full flash your 12585950 OS into it no problem. You will need to change the VIN manually as it will not be overwritten by the full flash.

ok so today i flashed the new computer and the full flash seemed to go ok, i proceeded to read the flash and that seemed to work also, only problem was no vin.. it should have retained the old vin no? so using the scan tool i set the vin. then i figured i would try to flash the calibrations and i get the same errors that the old controller gave me, it will only full flash....

i need to get a schematic showing the pinout on the flashscan v1 db9 connector and then i will make a bench harness to try to flash this out of the truck. if it doesn't work on the bench then i assume that there is a problem with my cable...

Tordne

January 3rd, 2010, 08:48 AM

The VIN is not overwritten by the full-flash like you might expect (it catches me occasionally too). You did the correct thing changing it through the Scan Tool. Once you did that you should read the PCM out again so you have a full image with the correct VIN to continue on with.

It just seems too weird that a cal flash does not work :nixweiss:

From the Tune Tool 'Help' menu there is a 'Help->Tutorials->Bench Harness Tutorial' option which showns the pin assignments for various controllers.
