You can save multiple tunes on the SD card that is in the hand held monitor. The SD card will also hold 100+ data logs depending on how big they are. The SD card pops out of the hand held and you can plug it into a desktop or laptop computer for tuning.

Most people talk about laptop tuning but you really don't need a laptop unless you are tuning at the track. I just pop the SD card out of the hand held and go in the house and use my desktop computer for tuning since the monitor is a lot bigger.

I'm not so sure the tunes need to be much different between progressive and 1:1 since it is all based on RPM and MAP. The only difference I've seen so far is the AE vs. TPS table since the TPS has to move a lot more with progressive.
