Auto Octane Adjust: Version 2.0
As we all know, 93 octane isn’t available at every gas station across the country — and even your local filling station doesn’t always receive consistent batches of fuel, So what happens if you get a bad tank of gas or simply can’t get the good stuff when you take a trip? Frequently, aftermarket ECU tunes require a certain octane rating and don’t take into account the fact that you may not always be able to run that same octane rating in your car.
Perhaps the most important aspect included in Gearhead’s tuning is its retention of the factory “auto octane adjustment” feature present in the ECU. This feature allows the ECU to self-adjust according to the type of fuel being used (be it 87, 90 or 93 octane, etc.). But, not only does Gearhead keep this feature, they improve it. Gearhead augments the factory auto octane adjustment strategy in a way that allows considerably more power to be made as you step up your octane rating (without changing the tune).
