First time I saw this one.

Some general comments:
1) The ECU is in the throttle body, which is a fairly warm place for computers.
2) They do not say if it is speed density, but it most likely is. Speed density does not play well with radical cams and low manifold vacuum at idle.
3) They say it will control timing advance, but the video didn't explain anything about how to do that or what ignition system is required.
4) They say nothing about what the air fuel ratio is at different loads and if you can adjust it. Nor do they say how the system determines what the engine load is.

It may be a decent system. My take is there is a whole bunch not said and too much how easy it is claimed. I would like to talk to some independent experts who have tested one, before I purchased one. Good luck.
