COBB Stage 1 + CAN Flex Fuel Power Package – 2022+ Subaru WRX

The COBB Stage 1 + CAN Flex Fuel Power Package is the complete, plug-in-friendly path to unlocking the real potential of your VB WRX on pump gas and ethanol blends. This bundle combines the Accessport V3 with the supporting hardware you need to take advantage of COBB’s CAN-based flex fuel strategy—so your WRX can safely adapt to varying ethanol content (including E85 blends) when running compatible OTS maps.

Whether you want a stronger daily driver on 93 or you’re chasing bigger gains on ethanol, this package is built to get you there with the right foundation: monitoring, calibration support, and the components required to run flex fuel correctly.

Why We Like It

If you want to run ethanol the right way on the VB platform, this bundle keeps it clean and complete. You’re not piecing together a flex setup from random parts—you’re getting the core COBB ecosystem that’s designed to work together, with OTS map compatibility and the monitoring you need to keep an eye on fueling.

Tuning Notes

• Compatible with COBB OTS Maps (use the correct map for your fuel and modifications).
• Flex fuel tuning allows the calibration to account for varying ethanol content (for example, E10 = 10% ethanol, E83 = 83% ethanol).
• Always follow COBB’s map notes and hardware requirements before flashing.
