If it failed, keep trying to flash it until it accepts a tune. Might not be this one, if it doesnt work go back to the previous tune so its at least driveable.

Trying V8 couldnt hurt, Paul/Ross say the V8 read/write scripts are more robust than the V7.5 ones. Remember you have to save the file as a *.ctd in the V7.5 tune tool to use V8 to flash.

Their is obviously something to be looked into so please flash with V7 pass-thru for the time being.

EDIT: We have been able to reproduce the issue so we'll be able to identify the cause.
