Another Decat question

[J@Y]

I have a decat for my 182.

When I fit it, will it bring an engine management light on due to lambda readings?

Also, there is a hole in the decat for a Lambda, should there be one or two for a 54 plate 182?

Thanks

Yes it will, although mine hasn't come back on for a while.

One hole in the decat for the lambda. Although nw performance forgot to drill mine so I just unplugged the lambda, couldn't get it outa my old cat anyway so that's a bonus lol.

Surely running the car without lambda will cause it to run badly? And/Or use shed loads more fuel?

Can anyone tell me; Does the change in lambda sensor readings after the car has been decatted lead to a noticable increase in fuel consumption?

Thanks

the lambda in the cat does nothing but read the emmissions, it has no effect on fueling, thats all down to the first lambda
