In my quest in bringing availability to boost the AR series, one of the problems I’ve ran across for majority of people would be the ecu and tuning. It’s been since 2009 the engine was released, and the “opensource” availability of the ecu have been few too little for the 2nd Gen tC. So, I have gone through the wiring diagrams and made an open pin-out guide/sheet for the 2nd gen tC. This pin-out guide is recommended to “piggyback” with the ECU. I will release different Guides and videos over time for different aftermarket ECUs. As I am only a humble fabricator, I am NOT a wizard in the arts of tunning and wiring. This is for others to get exposed and allow the performance community to grow.
