To get any kind of wave with two MP40s they will need to operate in anti-sync in the Short Pulse mode, that is, while one is ramping up, the other is ramping down. To do this they have to be in a master/slave group so that they communicate with each other. With the EcoSmart drivers and pumps postioned for a typical rectangle tank, opposite each other, the dial on the master will show the colour of whatever EcoSmart operational mode you are using, NTM, TSM, etc. The first slave on the opposite side of the tank should show an orange dial colour. If you have one on the back in the same master/slave group it's dial should light up turquoise. In any EcoSmart mode, there is no sync/anti-sync option, each pump is set up with a certain colour based on where it is located on the tank. The EcoSmart modes themselves take care of changing speeds depending on the EcoSmart mode selected.
If you were to use a second MP40 next to the master on the same side, you would set it up in sync so that they both push water at the same time. In this case, this slave would show a white coloured dial (sync). Sounds complex, but EcoTech has actually taken much of the guesswork out of setting up the pumps effectively with the EcoSmart drivers. A good short explanation of this is on page 32 of the online manual.
I printed a copy of the full instructions so I don't need to fire up a computer every time I need to refresh my memory, which is often. It's also a very useful reference for someone that may be looking after your tank when you're away. Techie or not, these pumps have a ton of options & if you own one or more, it's very worthwile to do your best to become familiar with what they can do. After all they cost a few $$$s more than your typical powerhead so you may as well get the bang for your buck.
