- | ====== ECU-based Boost Control Overview ====== | ||
- | |||
- | ECMLink's boost control mechanism is modeled after the factory implementation provided on 1995+ DSMs and Lancer EVOs. The most notable difference being that ECMLink's implementation provides gear-based control rather than a single curve that applies all the time. | ||
- | |||
- | The basic operation goes like this: | ||
- | |||
- | - Look up a base duty cycle from the Base Duty Cycle table based on gear and engine speed (RPM) | ||
- | - Adjust this value by some amount based on how far away current boost is from desired boost | ||
- | |||
- | This sounds pretty simple and it really is, but once you start picking about the phrases, you'll see it's a bit more involved than it might seem at first. | ||
