I'd be wary about using an ECU that has few MX5 users because you're going to be the pioneer on that ECU for MX5 peculiarities - pioneering takes time and time with a tuner costs lots of $$$.
eg.
The NB's alternator was traditionally painful to handle on most ECUs and some resorted to swapping it out for an NA alternator.
Now, after many years of use on MX5s, Haltech, Megasquirt and Adaptronic ECUs now handle it.
Does your ECU handle the NBs alternator properly?
If not, you'll never be happy with your car.
Haltech has had many years of involvement with MX5s and even with their latest incarnation NitroDann spent a lot of time identifying issues, including a harness wiring problem which Haltech should have been aware of.
The ECU rule of thumb is to use whatever ECU your tuner prefers but if it's untried on your vehicle, you could be in for a lot of grief and $$$ to figure out vehicle-specific issues.
Having said that, if you do choose the EMS ECU, please document it here "warts-and-all" - if it works out well the community would be greatful for another ECU option, if not we'll know to dismiss it.
