TDC Tuning has specialized and focused on Subaru ECU calibration utilizing open-source platforms for years. As we are some of the only current active contributors to open-source ECU definition development, we have the ability to produce new patches, extended tables, and custom logics that expand OEM ECU functionality that other tuners lack. Our capabilities allow us to offer OEM-quality flex fuel blending, true speed density fueling, custom map switching, and extended failsafe parameters that can auto-switch to safer maps to protect your investment from unforeseen environmental factors.
We are open to all levels of modifications, whether your vehicle is fully stock, full bolt-ons, or even fully built track cars. We offer in-person and e-tuning depending on modification levels and personal preference. Additionally we offer mechanical labor and advice for more extremely modified builds.
Although we focus on Subarus, we also maintain experience with Mitsubishi Evo, Nissan Z-platform, and other import ECUs using open-source, commercial, and standalone systems.
