Rabbit Due Open ECU now has 3D mapping! Up until the last few weeks, the timing and volumetric efficiency maps were both a combination of 2D tables. The timing advance was just like a distributor; advance = speed advance + vacuum advance.

This works pretty well for a simple engine. But you can get a lot better result with 3D mapping. Over the next few weeks I am hoping to have the C14NZ engine running a lot better with a nice 3D tune. Shown here is the base volumetric efficiency 3D map.

In other exciting news the Rabbit Due Open ECU can now be found in kit-form at our tindie.com store!
