My opinions:

Emeral is reliable hardware, if getting mapped by Dave Walker then it will be made to look easy, if getting mapped on the rollers by anyone else it will look reasonable, if you are going to map it on the road yourself though its like pulling teeth.
Ive been mapping it for years and years and still hate it


Megasquirt mapping software is very good but it is quite complicated for a first time user potentially, but not too bad if you have a good basemap.
Hardware is not great though, the main loom connector is shocking and depending on who made it potentially there could be dry joints and all sorts.
I have megaquirt from James Murray on my bike ITB corsa though and it works well and I like mapping with it.

Mtech V4 is all the plus points of megasquirt (other than slightly dearer) but with none of the hardware downsides, really good connectors, properly machine assembled etc, and this is what I personally would choose on your engine
I have this on my clio trackday car for example, which I bought for it when I went to ITB's (now im on a custom single throttle inlet instead though)
As per megasquirt, a joy to map once you understand the tuner studio.


Omex 600 is a good option too, Reliable hardware commonly used in motorsport and althouhg I think the software looks a bit cheap and cheerful I cant deny that it actually works very well, its easy to map yourself on the road and its very well supported by rolling roads etc to finish it off if you need to.
Ive mapped quite a lot of cars on this, and its definately one of the easier to use systems if this is your first time?



Realistically by the way to get good results you WILL need some time on the rollers, you wont be able to find optimum ignition on a throttle body engine on the road, its just not really possible.
