I installed a Lambda Link on Saturday and when I turn the ignition off the green led stays on for 30 seconds or so then goes out, is this normal?

Jake

anyone?

Where did you nick the +12 VDC feed from?

The green led should stay partially illuminated with the ignition on. Where did you connect the +12vdc and the ground to?

Some cars (including mine ) have an 'interesting' 12v feed to the stereo - when the ignition is switched off, it gradually drops to 0v over the next 2 minutes or so. A bit odd, but nothing to worry about the supply appears to be stable when the ignition is on.

All the connections are at the ECU.

My power is from the ecu too.... no such problems with mine. Immediately goes out after switch off.

Delboy... think your confusing this with the knocklink. The green leds should not be lit with just the ignition on.

But there is one green led that stays on. As far as I know you can use two connection points for the +12v at the ECU one of them must stay live for a few seconds after the ignition is turned off?

When does the clear (bright red) LED light on a Lambda Link?

Jake

Good question I was just thinking the same thing, perhaps when really leans out the big clear led flashes red like the knocklink.

Tone loc - On my Lambdalink(which I have just fitted) there is a green LED on the left hand side below the AFR LEDS, this illuminates green when power is applied. On the right hand side beneath the AFR LEDS there is a what looks like a clear LED(actually light sensitive, changes the brightness according to light)
It is imperative that the ground for the lambda sensor is connectedto the engine block as the signals you are monitoring are millivolts so the less impedance introduced into the ciruit the better.

I think that connecting the ground to the bolt holding the ecu in place is just as good. Can anyone confirm this??

Delboy2

On the Lamdalink fitting instructions it actually says to fit the lambda sensor ground to the engine block.

This is what I have used from the LL group buy. I think this was supplied by BRD

I followed the instructions as per Lambdalink packaging. As the sensor is located in the exhaust the best place to fit the ground is as close as possible to it as this reduces any added impedance to the circuity.
