I paid for EFLIve, why can't I flash COS3?

[mr.prick]

Can you flash at all or just not COS'?
Is the firmware up to date as well?

[Mr. P.]

I can read/flash/scan, just not the COS.

FIRMWARE = 2.04.70
BOOT BLOCK = 2.04.10

Joe, are COS's available to be used on ALL PCM's?
I thought they weren't?

Mr.P
What vehicle do you have?

[Tordne]

The gasoline COS's (other than the E40 2bar) are only for use with the 512kb and 1MB 1999+ PCMs.

Good point thought. I don't see that having been asked and it is an assumption that this is what is being attempted.

Can you please post a screenshot of any error message you are receiving? Also have a look at this page (http://www.efilive.com/index.php?opt...111&Itemid=121) and send any related .BLX file to support@efilive.com.

The truck is stuck dead in my friend's driveway. So I will have to get screen captures tomorrow.

The vehicle is a 2003 Silverado SS, current OS is 12593058, I am trying to flash COS3 03190003.tun.

Step-by-Step to recreate the problem:
1) boot laptop and flashscan V2
2) open EFILive Tune v7.5
3) open COS 03190003.tun
4) cut/paste the VIN from my truck into the VIN text box
5) click Flash menu item (first 2 options are disabled)
6) click 3rd option, 'Program PCM operating system and calibrations'

Software will show a dialog window saying that this requested feature is only available to Commercial and Workshop versions.

7) Click File menu option, click 'Close tuning file' option;
8) Click Flash menu option, click 'Read PCM calibrations' option;
9) Use dialog window to read entire PCM from truck, turn off key, wait countdown, dismiss dialog window
10) Save read PCM calibration to HDD
11) Navigate to B0702 Cat Low Protection Temp, increment temp 1-degree
12) Click Flash menu, Program PCM Calibrations
13) Use dialog window to write PCM calibrations to truck, turn off key, wait countdown, dismiss dialog window
14) Close EFILive.

I am a developer myself, I was very careful in testing to verify USB communication was NOT a factor. I will get screencaps tomorrow.

Its a licensing issue for sure, if you can read and perform cal flashes then for some reason the software doesnt think you have a commercial version.

Also, you're running OLD firmware on your V2, those are at least 6 mo old. I would suggest you download V8.1.2 and update the software like you do 7.5 then update the boot block and fw on your V2 to the latest.

I'm afraid I cannot duplicate your problem here, we'll wait for those screen shots.

Try uploading COS3 without your VIN number that you cut/pasted in before. Leave it as 00000000000000000 .

I'm pretty close to you , if you need a second opinion , I would be glad to come over and take a look .
PM me !

[Mr. P.]

OK Gang - whatever the issue was, updating the bootblock/firmware did the trick. I successfully installed COS3, walked through the tutorial, even drove the truck around for a few minutes.

Thank you ScarabEpic22 for the suggestion to update the Flashscan.

Now on to the next issue!!!
