Wastegate - Throttle position sensor

[alex nicu]

The TPS it's just a potentiometer whith a range between 0 and 5 volts. 
The only problem with this TPS it's that for throttle release the 
reading it's not 0 and also for full throttle it's not 5V . The range 
it's between 4% to 70% ( aprox ) . So , on my AIC , I make a calibration 
procedure to set release throttle and full throttle . 
I'm also thinking about one electronic boost controller . The only 
problem it's to find a good ( fast  enough) valve ( or maybe 2 valves 
like on PROFEC B ) to control the bleeding for the wastegate . 
On my AIC I'm using a 2D map ( TP and RPM ) and the MAP sensor like a 
variable limit switch . This one will be very ease to change in to a 
boost controller .
