De-cat pipe and lambda sensors...

[ian_jobson]

ok so if i had a decat (not sports cat0 for "track use" for example (i know ill have mot issues) how do i get round the lambda sensors?

 

[Martyn]

You'd need a stage 2 Revo map or similar...

 

[ian_jobson]

no other way round it i take it? what will happen without map?

 

[Martyn]

You'll get a CEL and more than likely 'limp' mode

 

[ian_jobson]

great

guess ill leave that off till i get mapped up then!

 

[Martyn]

Dont forget that the CAT is part of the downpipe bud.

 

[ian_jobson]

could use standard downpipe and cat tho? with the rest of the system?

 

[Martyn]

Rest of what system mate?

 

[t18con]

there is another way around the cel thing, by spacing the lambda out of the gas flow witha small spacer.

 

[Martyn]

It's a bit of a bodge though!

There is 1 expert who knows how to do it and he did mine today. You need to know the codes for the ECU - Jabba sport convinced me that they could'nt do but MRC tuning did it for me no problem

I had a de-cat on mine. Got the CEL warning and engine light but no limp mode . Sounds quality, quite miss it come to think of it
