Hi Adrian and All the rest of the Petrolheads ;-)

A good question ;-) I'll be giving trial and error a go !

Could someone please enlighten me...... why would you want the waste gate to 
crack before the boost set point ( just for the moment we are living in a perfect world 
where the waste gate stabilises the boost instantly ) wouldn't it be ideal ( quickest 
spool up time ) if the tubo got all the exhaust gas untill it didn't need more? 
Is the PID used as some form of traction control ie: it's programed so that the power 
going down doesn't make the wheels loose traction?

Sounds cool ......I've been looking at doing a couse at the polytech on micros as it 
looks like most of the stuff I want to build would be easyer to do using micros.

I'll keep you posted....
