I assume you are referring to the new Procal tool. The original Procal stored the performance tune and downloads the stock tune into internal memory. I'm not really sure but perhaps now everything is stored to the MMC - just my guess. The instructions say to install the MMC which should come with the Procal. You can download the instructions here.Hi,
does anybody know why there is a MMC storage card required in order to use the ProCal tool? I was under the impression that the tune is "on" the ProCal?
