A Nightmare. This is the worst app I have ever used. On an Android phone there are options you can't see or click. I can't get the basic options working with this MSD ignition box. MSD must of paid someone pennies to make this terrible app.

Navigation of the 3D timing map is terrible. You can't select more than one cell in the RPM and MAP column/row so you have to enter data in each cell individually. You should be able to scale map and rpm just like the timing cells. Map x .4 would get to 100kpa like most users will want. RPM x .75 would get the rpm table to 7500rpm instead of 10k. This allows a finer adjustment with more cells over a smaller range. You should also able to select a chunk of the map instead of only rows or columns.

terrible.. just glitches when I attempt to connect to my device.. flashes the loading icon and thats all it ever does. I can use the program without connecting to my 6al ultra box.. but won't let me connect in real time.
