Folks, what we have here is a failure to communicate. Was able to download from the VCI and record some runs even do smart tune. However was not able to reupload, the ECM  recalibrate flash button is greyed out and only smart tune can be ticked. The active fuel box is greyed out. 

So I thought I would just reload a std factory map and same problem can't  reflash with a std map, am. Missing something?

any suggestions peeps please send them thru.

cheers,

Clem
