Rx8 tuning help

[Jr_gosetto]

Hey guys I'm pretty new to the rotary scene. I know the engines pretty well at this point besides a few thing so if there is a link someone could post to learn more would great. im not to sure about how to tune the pcme. I have looked for piggyback's but I havnt been able to find any. So my question is can the pcme be open source tuned. I'm planing on doing a street port from mazdatrix bc i have ti rebuil the engine anyways and wanted to tune the engine aswell to try and get a few extra ponys. Any help would be much appreciated.
