The first thought that comes to mind is that you must have a 3-bar MAP sensor in order for the higher scaling to work. If you confirm that, then go to the FAST HELP menu to get detailed instructions on what Disco Stu said. (As a side note to Disco Stu, I certainly agree with rescaling for more resolution in street tune; need a bunch more cells under 100kPa and very little between 100 and 200, and then going over 200 becomes critical as well. (For anyone that doesn't know, below 100kPa is vacuum, 100kPa is zero boost, 200 equals 14.7 psi and 300 equals 28.4 psi.... therefore the necessity of a 3-bar MAP; kPa is simply the metric equivalent of psi.) Your boost will climb really quick between 100 and 200, therefore very little resolution is needed, but under 100 is where all the driveability is so more cells are ideal, and then exceeding 200 becomes critical as well, so I like a few more cells in that region also in order to fine tune. Best of luck to you!
