I just bought my FD3S about a month ago. It comes with a Blitz Access Ecu, the same as in the blitz/scorch drag rx7. I heard that the ecu is chipped (remapped?) in japan prior to ordering. U need to inform the current modification ( turbo,injectors,i/c,etc's ) of your rx7 and they'll mapped it to suit. Is this true? Can the ecu be tuned easily? Do i need a specific software from blitz to tune it?
