Our MSD Ignition is capable of 2 map that you can switch on the fly but you can save an indefinite amount of curves on the software. They do require the laptop to access though. If anyone has any further questions regarding the MSD unit post them on this site and I will reply or feel free to call me personally. I will gladly fill you in on all the details. If you are interested in reviewing the software it can be downloaded for free at the following link.
