A light weight Fly on the Focus you cannot tell it revs faster and it adds little to no power

As for making telling the ECU that its 5 to 10 deg cooler then it is wont do a thing on the Focus 20 years ago with the early ECU yes you could see some changes by doing it and in the end it spark knocked most of the time from the added timing , 10 deg now would add maybe .5 to 1 deg and it it wasent needed the ECU would pull it right out because of other things it is looking for

You are correct to a point adding more fuel does cool the Cyl but if you add more fuel and it isnt needed you loose power , just because you add fuel and cool the cyl doesnt mean you are going to make more HP or TQ
