I drive a 1991 Honda Accord EX, but i dont know what the sportshift does, or how to use it...does it eat gas, conserve, or it doesnt have any effect on the car wutsoever? I'd appreciate it if someone could explain it to me. Thanks.

 

It raises the shift point for each gear for part throttle. I think it holds gears a little longer when you let off the gas too.
