What you need is openport cable: http://tunertools.com/proddetail.asp...C-OpenPort1.3U

Ecuflash software for reflashingand modyfing maps: http://www.openecu.org/index.php?title=EcuFlash

Evoscan software for datalogging (and mony other things like actuator testing, bleeding the diffs etc): http://www.limitless.co.nz/

You may also want to read a bit on the openecu.org forums. One of the problems with Ecuflash is that it sometimes needs better definitions for particular ECU which can be found on those forums, sometimes particular maps may be notwhat they seem. (AFAIR boost control and knock control maps have wrong names often).



The above is true for Evos 7-9, Evo 10 is under development and previous ones cannot be reflashed this way I think (although I am unsure about Evo6).
