richard -

i'll be using my hfs4 on my 2008 subaru wrx with the stock ECU. is it safe to presume that i can use the 2011 sti wiring diagram from the installation diagrams in HFS4 or should i use the 2008 sti diagram from HFS3?

with the stock ECU being used, i would not be using the blue, MAP sensor, correct? under what conditions would one use or not use the blue/MAP wire connection?

thank you!
