Im not a fan of the edis module because of the way it manages to run the engine at 10 degrees advance even if the ecu fails or there is a problem with the wire between the two.
As a "get you home" its awesome, but if it happens on boost at a time where you are under 10 degrees advance for det it can be bye bye engine, I'd prefer just to have a misfire or the engine cutout.

For N/A though its kind of cool I suppose as 10 degrees everywhere on most engines will drive relatively well, but I still just prefer the idea of the ecu doing everything and if it fails then I'll just fix it!
