Lambda sensor

[trackspec197]

do you have to run both lambda sensors? The new system I've bought from a Clio cup race car only ran one sensor in the first cat and that's it. Can I do the same?

You can but it might turn up a warning light
You can map the car to solve this and any other things that might come with this changes.
(Fuel cons,flat spot maybe etc)

Yeah that's what I was thinking. I'll weld a boss in there for it I think.

You can buy blanking boss's that you could hook the Lambda upto; and then just 'tie-wrap' it up somewhere out of the way.....if this is help in your situation.

Might fool the car into thinking the second reading is always 'clean' (As it will always read the air inside the boss its screwed into) compared to the reading from the first cat - This worked faultlessly for me on a previous car.

The first sensor is the one that the engine uses for mapping. The second is to check if the "cat" goes awol. Plugging the second and Putting it in clean air thinks everything is OK.

All sorted now. I had a boss welded on.
