Richard this is exactly what I am doing. I am using a 5 way bosch relay(N?C) to open the hop switch circuit to the FIA.

Calvin I understand the resolution issues with the PSI 3. What happens to current between pins 3/4 when the WI injection boost is reached. i.e if boost is reached , does the PSI3 energise(close) the pin 3/4 circuit(current flows)? ATM the volt meter is not showing any current even at/passed boost point.

PS I am doing this to test the efficiency of my boost activation point(currently 1 bar). It is hard to change the hop switch everytime and to set the boost activation point easily. Also by setting only one parameter on data page 7 the map reading mirrors my boost guage quickly enough. I agree you cannot use the PSI 3 as a primary trigger for the 2D system.

Unfortunately it takes time to fine tune the hop switch and then datalog and start all over again.
