hi there, i'm thinking of getting a 4G91....anyway manual trans half-cut one is not widely available here but got a lot of Auto transmission one.. however i wonder is there any difference on ECU between 4G91 Auto and Manual version?? such as differet ECU code etc....or both Auto and Manual versions share the same ECU?

thanks a lot!!
