Efi live does not recognize os

[slows10]

Hi trying to write to my pcm. My truck is a 1998 S10 4 cyl. Efi live does not recognize my os. Then it could not retrieve the pcm serial number. Also it is coming up as a 1997 camaro. Ive included a screenshot. What am I doing wrong? thanks keith8422

[slows10]

we can read the pcm. also when we hooked up scan tool the os # that came up was 9356824 not the 19970100 that i showed in my screen shot.

Hi slows10,

Which PCM is in your S10...?

Where did you get the 19970100 file from...?

[joecar]

What happens if you try to write back to the PCM the 9356824 file that was read from the PCM...?

[slows10]

hi joecar my pcm is 16228016 I got the file from efi live when I read the pcm I guess lol. Not sure what you mean. thanks

[slows10]

What happens if you try to write back to the PCM the 9356824 file that was read from the PCM...?

I will try this now

Are you able to read the PCM OK? IF so what OS does it show in the calibration?

Is your software and FlashScan V2 firmware up to date? As at time of this post the latest versions are:
- 7.5.6 Build 117
- 8.1.2 Build 97
- FlashScan V2 firmware 2.06.35

Download updates as per this guide (http://support.efilive.com/kb_article.php?ref=5404-IJZV-0820). For V2 firmware updates check this guide (http://support.efilive.com/kb_article.php?ref=7243-SFGL-2949).

it appears efi live cant read my pcm when we are trying to write. It says its generating an os number based on my vin witch it says is a 1997 camaro. it is indicating an os number 19970100

[Tordne]

The read and write operations are distinctly different. What I was wanting to clarify is; are you able to select the correct controller type and perform a read (upload) operation on your PCM?

hi tordne, we did not install 8.1.2 build 97, because I thought it was for black box logging etc that we were not going to use at this time. Is it neccesary to load version 8.1.2 build 97. but we installed the others you listed. And yes we were able to read the pcm with the correct os number.

Im a little confused when you say read(upload). When I think upload, I think write to the PCM. When we select 97-02 Chevy S10 4cyl, we can read the PCM fine.

[slows10]

upon further reading I think we are supposed to download version 8 even if we dont need it.

[slows10]

uploaded version 8 no change. Did you guys look at the screenshot I posted? The top 4 lines seems to say what the issue is correct?

[slows10]

we are going to use the second license we have and are going to try reading and writing a v6 s10 1997 just to see if we have everything installed correctly

[joecar]

Do you have a FlashScan V1 or V2...?

If V2, then when you installed V8 you then need to flash V2 with new firmware (using EFILive Explorer).

[joecar]

hi joecar my pcm is 16228016 I got the file from efi live when I read the pcm I guess lol. Not sure what you mean. thanks

I will try this nowWhat happens when you do this...?

[joecar]

it appears efi live cant read my pcm when we are trying to write. It says its generating an os number based on my vin witch it says is a 1997 camaro. it is indicating an os number 19970100Can you post these files:
- the file you read from the PCM,
- the file you're trying to write to the PCM.

[joecar]

hi joecar my pcm is 16228016 ...What vehicle was this PCM from originally...?

[slows10]

What vehicle was this PCM from originally...?

A 1998 s10 4 cylinder. Anyway we just tried reading and writing to my brothers 1997 s10 and everything worked fine. When we hooked it up to his truck it asked us to licence it and we did and it worked fine. When we tried to write to my 98 s10 it didnt even ask us to liscense it. So im thinking my o/s number is not supported by efi live yet.

[joecar]

I thought 19970100 is a 1997 Corvette LS1 OS...

[slows10]

I thought 19970100 is a 1997 Corvette LS1 OS...

Efi live says is from a 1997 camaro. I attached the file I pulled from and tried to write to the PCM. I really think it has to do with the licensing as this same procedure worked with my brothers s10. Is there a way to tell if my os is supported?

[slows10]

well weve tried everything,checked every update installed all firm ware etc. it works on one vehicle and not the other. Also just after we try to writ to my ecm the security light is on when it should not be. then I go to start the truck and it starts and runs for 3 seconds then dies. After I disconnect the battery and clear the pcm it will start and run fine. So is the o/s number I gave you supported? This is the answer I need. 09356824 have you ever seen this o/s number yet?

[slows10]

This is a v2 scan and tune i paid 799. On my blue paper that came in the box it said it was commercial scan and tune . I thought this wasnt right. I would think I bought the personnel scan and tune. Does this info help?

If/when EFILive attempts to read the operating system number from the PCM and it fails, EFILive then looks at the VIN to try and determine the vehicle type. It will assume the vehicle is a 1997/1998 F or Y body based on the VIN. Seems like your VIN is reporting back as a 97/98 F/Y body vehicle (i.e. Camaro or Corvette). What VIN and OS (and associated explanation) is displayed by EFILive when you connect up the Scan Tool software? The VIN and OS and explanation are displayed in the "Console (F6)" tab page of the scan tool.

Blacky, I think you are correct, it assumed our vehicle is a 1997 F body when we tried to write using the tune tool. When we connect with the scan tool the correct vin (1GCCS1447w8167329) and the correct os (09356824) are displayed. I assume there is no explanation because there is no issue reading the vin and os numbers. However when we we first started the scan tool and entered my vin number, it said the vin is not recognized and no manufactuer specific parameters would be available. I'm not sureif this makes a difference as I said before, it was able to read the vin and os numbers. Thanks for your help

[slows10]

Just to add this 1998 S10 always had the original pcm, it has never been swapped. This is the first time ive tried tuning this truck and im the original owner.

[slows10]

I should be selecting the controller type as 97-02 4cylinder correct? And not the 98-00 vortec correct. Might be a silly question but who knows. Even though my 2.2 is in the vortec family it is the 2200 sfi vortec

[Tordne]

Wow there's a lot of posts here in such a short time :shock:.

For FlashScan V2 devices it is necessary to maintain both the V7 and V8 software and firmware versions even if you are not using the BBx functionality. The software and V2 firmware have are codependent.

That controller selection is correct based on the VIN provided.

So the fact you can read the eCM correctly and it shows the correct OS# is good. If you modify the file read out can it be flashed back to the PCM?

[Blacky]

There was a bug that sometimes caused *.tun files to be read out of 4 Cyl PCMs with a corrupt first block. That in turn *may* cause trouble for the EFILvie software to identify and therefore flash those corrupted *.tun files.
That bug is fixed in the latest pre-release software available here: http://forum.efilive.com/showthread.php?13991-July-03-2010-Pre-release
It would be a good idea to install the latest pre-release V7.5 and V8 software, update your FlashScan firmware* and re-read the PCM, then try flashing in the newly read (and hopefully non-corrupt) *.tun file.

* The process for updating FlashScan's firmware is explained in the document Start->All Programs->EFILive->V8->Documents->Upgrading Firmware

That was it blacky. The pre-release update you provided seem to be the fix. Everything seems to work good. Thanks for your and everyone else's help.We were a little bit worried that we screwed something up with the tool. Mild panic started to set in lol. Thanks, Keith
