Show original supplier description
The COBB Tuning Accessport V3 is the world's best-selling, most flexible, and easiest-to-use ECU upgrade solution for your Subaru. The device features a large, full-color, high-resolution screen capable of displaying up to six parameters in real-time, such as boost levels, 0-60 mph times, and trouble codes. This Accessport allows for simple installation with intuitive on-screen instructions that identify your vehicle and available maps. It also offers a straightforward uninstall process to revert the ECU to its original state. Beyond performance tuning, the Accessport functions as a diagnostic tool, enabling you to read and clear engine trouble codes, potentially preventing costly dealership visits. You can store up to 100 maps from COBB's Off-The-Shelf (OTS) database or from custom tuners, allowing for quick switching based on your needs. The Accessport V3 also includes a performance measuring suite to track metrics like 0-60 mph times, 60-foot times, and quarter-mile ETs, along with a customizable shift light feature. For data analysis, it supports recording multiple data channels simultaneously for up to 10 hours. The device can be connected to a PC or Mac via the AP Manager software for managing maps, downloading data logs, and updating firmware. It is compatible with USDM vehicles only. Included in the box are the Cobb Tuning Accessport V3, a mounting plate, OBD2 cable, grey faceplate, storage case, and user instructions. It comes with a 1-year COBB warranty.
