I will say it once again. MS is not a world-class EMS. It's cool for tinkering, and it provides CHEAP EMS functionality, but it's not world-class. Here are just some of the ways MS won't be as good as an Autronic, for example:

-Linear IAT compensation map
-2D, linear coolant map
-No charge estimation map
-No engine load relative to ambient pressure
-Very sketchy acceleration enrichment handling

Some of the MS versions also have:
-Maps that are too small
-Hardware that is insufficient to drive certain GPOs.
-Forced batch firing due to its inability to see a 24/1 cam pattern on the 3S engine.
