Who has installed an APEX turbo timer on an STI ?

I need to know which wires you spliced into at the ecu. if i do not run these wires, will the tt work properly, i am not concerned with the actual a/f function on the tt.

its the same as a normal car if you dont want a/f ratio

just make sure theres the parking brake sensor there which im SURE there is, just splice into that, i have mine running in my rs w/ no ecu splices just fine just had to cut the ignition wire to my alarm system

yeh i saw that a few weeks ago, but my sti is different. i just was not sure if it would work right without the a/f spliced, but its been fine

Hey I checked that link but couldnt get it to load. That turbo timer looks nice and id like to get one that installs in the same spot on my STi, also does anyone know if one can wire the alarm system's and the turbo timer to work together? Id like to get a nice alarm system, maybe viper or other (suggestions) but I would like a turbo timer also because most of the alarm systems only keep the car on for 2 mins max which from what I understand is somewhat less then optimal.

My HKS Type-1 TT came with instructions for a 2002 WRX so I found the 2002 ecu pinouts off of Ravensblade's website and cross-referenced the two so I could figure out what Subaru called each sensor.

Then I looked up those sensors on the STi ecu pinout (ECM I/O Signal) from the manual I downloaded and got this:

Plug B134:

Pin 23 = I RPM

Plug B135:

Pin 5 = B 12v Switched (ignition)
Pin 19 = U 12v Constant
Pin 27 = S Speed Sensor

Plug B136:

Pin 3 = #4 injector
Pin 4 = #3 injector
Pin 5 = #2 injector
Pin 6 = #1 injector
Pin 22 = P (FCD)
Pin 23 = P (AFR) Air/ Fuel

Plug B137:

Pin 1 = E Ground

*There was no TPS info for our ECU I guess because we are drive by wire but this was the info on the diagram for the STi:

Plug B136:

Pin 18 = Main; Fully Closed = 0.6; Fully Open = 3.96
Pin 29 = Sub; Fully Closed = 1.48; Fully Open = 4.17
