Not sure what I'm going to use yet. That board does actuator movement only and gets input from ethernet, for now I'm going to control it from software on a laptop, but eventually I want to develop an entire ECU on a couple pic32 micros. As of right now I have a USB boost/exhast press./egt board for my laptop... I'm actually working on my own SMS-controlled 2 way remote start car alarm that will probably also get integrated in somehow..
I think this is the basic idea of how the code is gonna work:
1. try to maintain X psi of boost
if boost > X, open vanes unless fully opened
if boost < X, close unless fully closed
2. if exhaust pressure too high, open vanes even if boost < X
3. if egt too high, fully open vanes, sound alarm
after i get a throttle position sensor in, X will vary based on throttle position, i'm probably also going to add a smoke button that will fully open the vanes on demand
