This is apparent when the car is in top gear and you floor it. Rpms build very slowly. Compare this with first gear, where its at the gear's speed limit. Doesnt take a lot of throttle to get the rpms to climb further more quickly.
The engine cylinder firing is an indirect effect of having the throttle depressed. The ecu just measures the air that you are letting in and adds fuel and spark timing.

What I was getting at when posting about increased RPM is when you push the "go peddle" the RPM via tachometer sweeps across till however long. What I dont understand is how is WOT unrelated to RPM when pushing the go peddle increases the RPM via tachometer? It doesnt make sense to me, mainly because I cant tie the the actual function behind them. What is the difference between WOT and RPM? I'm super basic when it comes to cars, but I want to learn and that is why I ask and I feel real stupid asking this but I'm doing it anyway for myself and the next guy. Basically I'm having a hard time understanding how WOT is achieved when you guys say RPM and WOT are unrelated when in my eyes, when I push the gas peddle RPM's go up via tachometer. You can PM me if this is getting too off topic.
