So what you're saying is that if I have the A/C on, I need to get into the gas pedal more to experience the same performance?
-yes for part throttle, but at WOT the A/C gets killed. But the ECU might fiddle with the throttle to hide this. I never felt the A/C from a power perspective with my T5 95SET, so its small stuff.
At WOT, compressor is kicked off, and all is the same.
-yes
At idle, there's an active compensation, and all is the same.
-yes
Everywhere in between, it's not really compensating for me. I've gotta do it with my foot. So unless I'm going balls-out WOT the whole time, I'm gonna get performance loss with my A/C on. Boo.
- not really a performance loss as you are moving the throttle all of the time when not steady speed and when steady speed performance is not an issue. And when you are playing with the throttle, you get what you want.
I would have done it such that torque output is directly linked to pedal position, and the system compensates for things like A/C. So when I've got the pedal half way down, whether I have A/C on or not, I get 50% of max torque at that RPM. Oh well.
- I don't know how that would work.
