Checking wideband lambda

[Ant.]

Right then , I am now in a position where I need to check the readings that the Innovate system is telling me.
I have checked that the Emerald system is reading the same as the Innovate, so am happy in that respect.

What is the best way to do this?


MOT station? will they be able to give me a lambda reading ? Will it make alot of difference that they will sniff up the pipes instead of where my WB sensor is?(bottom of Y piece).

What's the actual question ? Is there something wrong with the wideband ?

[Ant.]

No , nothing wrong, but it's a new installation, and I just want to confirm that what the system is telling me , is correct.

You can check it with the sensor in the open air, forgotten what it should be but a quick google will reveal what the oxygen level is normally. It won't work in an exhaust due to residual gases in the system.

Ok, I did the free air calibration, but now take a reading in free air?
Sounds simples.

Perform the free air cal, then take a reading in free air-should be 20.9%.

I always found the Innovate reliable.

I guess you didnt read the instructions with your Innovate that explains this stuff ?

Cheers Steve, 20.9%? Will I be able to see this on the Logworks software? At the moment the "gauge" on there reads AFR or Lambda.

Something not very helpful

Yes I did, I have done the calibrations as per manual, maybe your superior instructions state what the free air reading should be, mine doesn't seem to include that snippet.

Ant, yes you will need to start up the logworks.

Im quite surprised to see that the instructions dont include this !!!!

On page 7 of the LM-1 instructions it does, but for the more common LC-1, it doesnt include this information. Although they use the same system.

Ok, sorted it now. Got home and pulled the sensor out, ran logworks and it showed about 19.8%, re-calibrated it and now it shows 20.8/9%.

So that should be happy days now then.
