Yes, it will be. The H4 has two dedicated Di inputs, one will work with the MZS3 and MZS6. The other is for VW FSi engines.

I know the MAZADASPEED ECU quite well. It is weird how it switches, firing alternative injector banks between + and -. On the MZS6, you can tap the injector signal before the driver, the injector signal is individually driven.
