Tactrix OpenPort 2.0 | ECU Reprogramming Interface — Subaru, Mitsubishi EVO, Toyota, and Mazda

What is the Tactrix OpenPort 2.0 — and what is it for?

The Tactrix OpenPort 2.0 is the industry-standard interface for ECU reprogramming in Japanese sports vehicles — especially Subaru WRX and STI and Mitsubishi Lancer Evolution 8, 9, and 10. Used with EcuFlash software, which is J2534 compliant, it allows reading, writing, and modifying parameters of the vehicle's original ECU.

Key feature: datalogging directly to microSD without needing a connected computer during use.
