After picking up(yet another ecu) from emerald yesterday, this question is going to be answered by Emerald themselves.
But as I read it you just go to F8, to LIVE UPDATE, put in new figure/s press ENTER all done.
I am not versed in these things though, so when discussing it, dave said he/karl would answer it, it may be a little delayed though.
He had yet another INNOVATE LC1 controller that was fubbared yesterday, glad I bought Tech Edge now, skint is not the word!!
