This is for port injection converted vehicles ONLY. The direct injection no longer works and GDI Injectors should be removed, and blanks fitted. All PFI injectors are supported.

PFI Injector harness can be ordered as well with customer specific injector connectors, otherwise injector outputs are provided in the auxiliary injector connector.

Alternator, Oil level, Oil Temperature and Waterpump BSD control is built into the adapter.

Some R8 coil looms available for the OEM ECU will not be compatible with a MaxxECU! Contact the coil conversion manufacturer to verify that their coil loom is compatible with logic 0-5v signals.
