COS5 upgrade issue

[lastcall190]

So I am following the tutorial to the T right now... and have run into a problem almost immediately. I pulled the tune that's on there right now, saved it, everything is fine. I hit step THREE, perform a full reflash of the COS, and it wont let me. It's barking at me to "save the current calibration before reflashing". I downloaded the 02020005.cal file, put it practically everywhere on my computer. Nothing. What am I doing wrong... AGAIN :bash:

If I understand correctly (I'm capable of missing...)...
did you save the file you edited (the one to which you copied the tables to)...?

Yea after I pulled the tune that was on there, I saved the file. As I understand it, I use that file AFTER I flash the "02020005" file, as a calibration only flash. Right? Just getting there is a problem for me :D

I pm'd Tech Support.

Oh so it's not simplistic user error then, that's refreshing. Thanks, had I known I would've just PM'd them rather than having you pull the leg work.

"save the current calibration before reflashing".

You will get that message if any changes are made to the data in the *.tun between loading it from disk and flashing it into your vehicle. To see what changes have been made, select the menu option: View->Calibration window, then click on the [Modifications] tab page. If that is empty (i.e. no modifications), but EFILive is still telling you to save the current calibration, then there is a problem with the software.

Note: the message does not have anything to do with *.cal files. By "save the current calibration", it means save any modifications that have been made to the *.tun file. The message is worded that way because the *.tun file contains calibrations and the calibrations are what get modified when you edit the *.tun file.

On the other hand, the *.cal files contain the information about the calibrations in the *.tun files. Information EFILive needs in order to be able to display the calibrations in engineering units (like rpm, kPa and DegC).

OK I think I follow. What I did was change the VIN to my vehicle's specific VIN. Would THAT be causing my issue? That is the absolute only thing I did. Good point, thanks, didn't even think of that.

Yes, that would cause the message to be displayed. Don't change anything before flashing in COS5. You can change the VIN later.

Thank you. I will check it out again tomorrow morning, I have no doubt it should work now. Didn't realize I could just change it later.

I did the COS 5 w/ the Vette this spring, I have a thread detailing all the issues I encountered, the forum was great, many PM's and a few phone calls to the guru's, they all helped out.
