I have an SDS EM-1

It is set up to be used on a 2 rotor wankel engin in staged injection mode
thus i have 2 Primary 2 secondary injectors, the injector driver is of the peak and hold 
type.

The setup is easy you have a small hand held 2X20 lcd with 7 push butons all u have to do 
is cycle through the diferent values ....etc

It works fine, easy to tune, A neat mixture trim helps you get a rough mixture closer to 
what you are looking for it varies your seting by +- 20%.

I have not had any problems
All sensors and wires are included but the injectors are left up to you and the manifold 
pressure sensor are optional.

I opend up the box and found not much filtering, shielding,the cpu is a Motorola 68HC11
8bit micro,the code is set up as 8k eeprom data for the look up table and 8k code of 
programing.
 
If looking fore a racing box i would not recomend this one unles u have R type ign wires, 
and the box is in the car.
 
I could be emailed for more info.

             Thanks!
