First try at flash - have problem

[voda1]

Car is 97 Vette. Loaded my saved orig tun file and made 2 changes to the stock tun file. Saved changes to new file. When I try to reflash this message displays:

EFILive has detected that this pcm does not have a valid calibration.

EFI can still read the damaged calibration or reflash a new calibration.
Click ok to continue...

Do I need a different pcm?

When you read the OS/cal what does it say?

[voda1]

19980200.cal
v7.81 01/30/06
cal id 9352010

To me it sounds like EFILive 'thinks' the PCM is not 100% functional because the PCM did not respond to a request of some sort.

If you can locate the folder on your PC -
\My Documents\EFILive\V7\Bug reports

in there will be some files with the extention .blx
If you can send the ones you have in there from the date you tried programming to support@efilive.com then we can take a look just to make sure it's a false warning.

Cheers,

Currently using V7.3.1. Should I upgrade to v7.4.2?

Problem solved - must turn key to 'on' postion instead of 'accessory'.
