Sounds good. We'll see how it looks. Glad it felt good.
The sport pedal just tightens up the throttle pedal to throttle plate relationship as you go up in rpm. From the factory, the pedal relationship is very lazy, meaning you are pushing the pedal more percentage than the throttle plate is opening. The stock pedal map, say you're accelerating with 30% throttle pedal movement, the throttle body is only opening 19%. In the sport pedal, I tighten up that relationship so that it feels more direct, like if you're pushing the the pedal 50%, the throttle body is opening a similar amount. It doesn't make the pedal physically feel different, but it makes your brain feel a more one to one feel if that makes sense. I don't make it exactly one to one, which would make it touchy, but I tighten up the relationship. The pedal map in your file is my base pedal map, so it's already been adjusted over stock, but the sport pedal map makes it a little more direct. I throw in the sport pedal later in the tuning process so you're not on sensory overload in the beginning.
Technically no it doesn't take the ECU time to learn. As we remove knock, the knock control value goes down and it stops removing timing proactively to prevent knock. So, now that it's been knock free for some time, the ignition being delivered is what we have programmed. The ECU is always looking and learning where knock may potentially happen, and works to stop it proactively by introducing knock retard while driving even when knock isn't present. It's doing less of that now, so that is probably what you're feeling. Could be partly intake temps if it was cooler today or something like that as well. But most likely it's the ECU lowering the k control value and begins to deliver the ignition we have programmed. Which is exactly what we want.
