Anyone has any update on SCT?
The car is not "tuned" specifically for 87 octane. The stock ECU is able to advance and retard timing as octane increases and decreases, with a minimum spec of 87 octane. Don't believe me? Hook up an OBD-II logger to your car, put in high octane (or even better e85) and watch the magic.When a car is "tuned" several aspects of the factory settings are changed. Timing advance or retard is one of them.
