lambda T2 ecu

[cosworth]

I have a T2 ecu on suzuki gsxr600
i would like to get the lambda into the t2 ecu
i'm using a bosch 4.9 sensor

pin1 is going to pin 5 of the t2 connector
pin2 to pin 4
pin3 to pin 15
pin4 to 12V+
pin5 to pin 7
pin6 to pin 2

but i won't get the signal into the ecu
in the t-win sofware it shows lambda is 0.000 and sometimes -0.001
Does anyone knows why ?

thanks in advance

Hi,
Your pin-outs seem to match the wiring diagram - have you ticked the "internal lambda" box in the sensor configuration / lambda sensor page?

This took me a while to figure out (basically one at a time per pin referencing the Bosch 4.9 data sheet by process of elimination) It seems every on-line diagram has different pin-out numbering which isn't helpful especially when labled with only a symbol or letter none of which correspond to the DTA pin outs wording - its bloody frustrating and its only 6 pins!

Pin 1 = pump cell Pos - red - = dta t2 pin : 5
Pin 2 = pump cell neg - yellow = dta t2 pin : 2
Pin 3 = heater neg - white = dta t2 pin : 15
Pin 4 = heater pos - grey = dta t2 pin : none separate 12+v supply
Pin 5 = cal resistor - green = dta t2 pin : 7
Pin 6 = ref cell - black = dta t2 pin : 4

It seems maybe pin 2 (sensor) is interposed with pin 6 (sensor) ? ? ? Whether this cures it I don't know! It one advantage of using a standalone controller and sensor - they plug together and just work.

If DTA pinout info is not good enough, that needs improved.

But onboard lambda control is far better than relying on external controllers, even more so if you're relying on an analogue voltage input from said controller, especially Innovate stuff which is renowned for having voltages all over the place.

This is wired correctly.
You must turn on "Internal Sensor" in the Lambda Sensor settings.
The sensor will then show in the Diagnostic Display.
It will not read anything until the engine is running, as powering the sensor before the engine turns on will break the sensor very quickly.

Sorry if the above confused the issue - i'd still be confused!

surely the colours define it and make it easy to get right then ?

it worked now, thanks everyone for the tips and explanation
