Anyone ever get any further on this? either with that Mitsu/Mazda GDI box, or any other option?

Do you have a test mule engine?

BMW 760 e65/e66 had separate electrics boxes just to drive direct injectors - those were the early days of GDI. Each v12 engine was running using two of these blocks - each box controls 6 lowZ injectors. Overall they had 5 separate control units to server that v12 engine.

We got one of these boxes - bosch 7506280 from BMW 760 - to click a GDI injector. Two wires to GND, two wires to +12v. Low-side control signal - and it's alive Next step is hooking this to an oscilloscope.

Oh, I've purchased a GDI test mule!

Two months ago already, and made exactly zero progress since

GDI status update: Nick make a step forward - OEM box from BMW 760 is in charge of high voltage injectors for now. This gives us a baseline and a way to test the fuel rig before we migrate to our own high voltage injection control.
