Hi, I came to this forum as it seems that this was once the hot place for the A'pexi Power FC hacking....
I'm actually a Subaru owner, but have a strong background in electronic engineering and software development.
(But my Subaru bizzarely does use RX7 Air filters: ARC tuning used standard sizes.....)

I intend to restart the open source ecu hacks and interfaces, at least from the ground up, if possible.

I've posted my thoughts and intentions to the Power FC forum, where I'll probably be staying for a while :-)

Hope its all good,
Edwin
