You can use either Toyota or VAG COP units with the Gen2 ME221/ME442 Plug-Ins. These are "Active" style coils.


COIL 3 and COIL 4 trigger signals come out of the AUX Plug on the baseboard.


COIL 1 and COIL 2 should be triggered from the stock ignition trigger pins. The pins of the stock ECU are listed in the tables in the appendix of each models specific Hardware Install Guide.


The GROUND and POWER supply wires should be heavy gauge. Note they should be neatly grounded to the cylinder head. Failure to do so can create electrical noise which can effect USB operations of the ECU.


The OEM 12V feed (taken from the place the OEM coils were supplied their power) should be used to power the new coils, and should be rated at around 10A or more.


It is always best to run new wiring instead of using OEM triggering wires and power wires as COPs can draw significant amounts on current.


Once you have wired them, test them as usual using the test output function. Then, change the Ignition mode to Fully Sequential in the Ignition Driver, and finally, check that COIL 3 and COIL 4 are assigned to COIL 3 and COIL 4 in the Output Settings. Be sure to check dwell settings as recommended by your coil supplier to avoid damaging them.


Note that if the engine runs fine when set to "Wasted Spark (COPS)" but does not run in "Fully Sequential" Ignition modes (yet still sparks as expected) you may just need to add/subtract 360 degrees from your trigger offset to align the ignition event with the compression stroke as opposed to the exhaust stroke.


VAG COILS Shown are the LONG/NORMAL Type. Other pinouts exist. Confirm yours before wiring.
