Simple ECU flashing with gauge package! The new in-cabin mountable Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time.
Fully customizable from the look (multiple bezel colors), layout (set up race, street, or dyno gauge clusters), and mounting options (choose from 1,000s of standard vehicle mounts). And what's looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs.
This is your new Accessport.
For those looking to add a bit of power to their Ascent, two versions of our Stage 1 OTS map are available for the Subaru Ascent. A Stage 1 87+ map is ideal for those who want to continue putting lower grade fuel in the tank but may want a slight increase in power.
This calibration can safely be used with any fuel ranging from 87-93 octane. For those looking for a larger bump in power over stock, the Stage 1 93 map file provides even more power and torque gains across the board. This calibration does require users to run 93 octane fuel to prevent more significant knock events.
During development, we discovered that Subaru truly calibrated the ECU to use an 87 octane fuel and testing with higher octane fuel while using the factory calibration did not impact the overall power of the engine, though it did clean up occasional minor knock events.
