I have five take-offs for manifold pressure (below throttle body), the 21 has five takeoffs conveniently!
-MAP sensor. Don't tee this with anything. You need a clean and fast reacting signal for the ECU, the quicker it reacts the less transient you need.
-Dump valve
-Fuel pressure reg
-Crankcase breather (inc 1-way valve & restrictor)
-MAP Boost gauge
NOTE: You will also need brake servo with 1-way valve, my 21 has electronic assist and doesnt have a servo.
I have another above the throttle body which splits out for
-Pre throttle boost gauge
-Wastegate control
When you start using WARI it's tricky learning the screens and how it all links together. When you get the hang of it it kinda clicks. There are some great screens built in to help you, like the F11 ECU Data window that I showed you yesterday and the Calculation trace window...that has been fantastic for me in setting up good idle and troubleshooting.
I also recommend you set up the two boost gauges, above and below the throttle. Its very educational watching the differences, and how the boost works around the throttle. They only ever match readings on heavy or full throttle. Use the OE dash one for above throttle if you like.
