Increase power and mpg?

Postby Motopsycho87 » Tue Nov 22, 2022 12:15 am

Hi all. I'm interested to know how with a remap are people increasing power and economy when doing a remap? I can understand one or the other but not both? Can anyone tell me the science or logical reason behind this? As to me if you increase fuelling to gain more power, you're using more fuel? Or am I missing something? I'd love to see the difference between a good example of a standard map and a tuned map to see how it's achieved!


If you can't tell I'm very new to this!

It's not too difficult to explain, most cars have a built in safety limit. They keep their specs well below limits of the car.
VW are most guilty of this, they use many limiters to save car parts to last longer.
Turbo's and Clutches are examples of their restrictions.
So on this particular mark you can raise turbo pressures and lift Torque limiters so the clutch has more to do.
More power and more economy strangely as the foot is less on the pedal for the same speed.
It's more complicated than this but you get the gist.
