AlphaECU Plugin for Scion tC (2005–2010)
Unlock the full performance potential of your first-generation Scion tC with the AlphaECU Plug-In—the ultimate upgrade for drivers who want more power, sharper response, and complete engine control without sacrificing OEM reliability.
Designed to plug directly into the factory harness, this ECU replaces the stock unit with zero wiring cuts or modifications. All factory systems continue working exactly as Toyota/Scion intended—from AC to gauge cluster and everything in between—while giving you access to powerful tuning features the original ECU simply can't offer.
Whether your tC is turbocharged, supercharged, or naturally aspirated with bolt-ons, AlphaECU gives you the headroom, stability, and control needed for serious performance.
