[QUOTE="richardtan, post: 3481675, member: 73917"] Hi ZTH, I am new to car modification. I have a stock Toyota never been modified before in anyway. Am thinking about saving fuel using SC. Please could you confirm for me if the following understanding is correct or not: 1. when induced air (compressed) goes into a car , the O2 density will increase for the same volume of air taken into the cylinder and O2 sensor measures this and pass this info to the computer which then adjusts more fuel to be injected into the chamber to get the right mix to enable combustion. So, this means compressed air will actually require more fuel, am i right ? Assumption is same level of acceleration applied on the accelerator. Hope you don't mind my novice question but I am very interested to get confirmation on the above. Have a nice day. regards Richard [/QUOTE]
