Wondering if there is a document out there ...

im looking for ECU wires to tap for an HKS Camp system...

thanks

I can look into after work on Tuesday. I have the shop manual, so maybe it'll be in there.

that would be great !

i only need :

RPM Signal
Speed Sensor
Injection Pulse

let me know ... thanks

Speed sensor and tach wire can be found on connector I11 on the back of the gauges I11 is a ten pin connector , the smallest. Blue/green is the tach (c5 -toward the center) and green/black is the speed(c2 on the end) . I know they both work bcause i use both. Injector pulse i will have to look up.

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

Pinouts are here (http://www.phear7imports.net/subs/btroop/trey/STi/files/05.%20Engine%20Control%20Module%20(ECM)%20I-O%20Signal.pdf)

You might have to go to page 2 then back to 1 to see page 1.

hmmm ... RPM and Speed sensors are quite obvious ... i dont know what people use for injector pulse ? maybe any of the 4 injector wires ?

any one has wired a HKS CAMP can shed any light on this ?

thanks for the help guys

RPM and Speed sensors are quite obvious
The problem i ran into was the difficulty in tapping one of those wires (can't remember which one-tach or speed?) because it is buried in the center of the plug.Thats why i suggested picking them up behind the gauges where there is room to work.Up to you of course.

So when we're measuring Air/Fuel Ratio we should tap into the Mass Air Flow Sensor?

Is there any wire for measuring EGT's?
