ECU / Lambda Sensor Wiring
I'm in the process of fitting a Stage 3 closed-loop fuelling kit from Stu, and could do with a couple of bits of info 
My car is a red-top 4x4, but the loom has a lambda sensor connection on the drivers side chassis leg. I've cleaned up the plug and put a meter on it. As far as I can tell, the wires are:
BN - Earth
BK - Heater +ve
BN/WH - Signal
Is this correct?
The other thing I could do with is an ECU pin-out diagram. I seem to remember there was one in the destructions for my SECS monitor, but god only knows where that is!
Can anyone help?
Cheers!
Neil.

Pin 2 is signal on the ECU for the lambda
SECS wiring is:
PIN 8 (BLACK) > ECU PIN 1: GROUND
PIN 7 (RED) > ECU PIN 20: 12V POSITIVE SUPPLY
PIN 5 (PURPLE) > ECU PIN 25: IGNITION SIGNAL FOR RPM READING
PIN 4 (GREEN) > ECU PIN 17: THROTTLE POSITION SENSOR
PIN 3 (BLUE) > ECU PIN 29: ENGINE COOLANT TEMPERATURE SENSOR
PIN 2 (YELLOW) > ECU PIN 31: AIR CHARGE TEMPERATURE SENSOR
PIN 1 (WHITE) > ECU PIN 15: MAP SENSOR

I'd expect no less!
I'll give you a bell if I get any questions specific to your kit... Just getting the more general stuff out of the way before I trouble you

In a nutshell....
Ł250 for the hardware key & software.
Ł80 - Ł180 for a lambda sensor depending on options.
Ł20 for teh stainless steel boss for teh exhaust.
Ł20 to weld it into teh downpipe if you dont want to do it prior to teh visit.
Ł50 to wire the lambda into the management system to get the signal and heaters working.
This will give you total closed loop fuel control.
Bear in mind i dont do the sofware off teh shelf for any larger than 803s. If you want 400s or larger i will ONLY live map it.

My downpipe allready has the lambda boss just before the bend near the turbo, would this work ??
Also i have 400's so would require a live map aswell.
Are there any benifits of this sytem Stu ??
