Fitting decats

[G1uk2010]

Did I read somewhere on here that fitting decats normally causes EML issues?? Or am I imagining things (again)

[GMballistic]

It can cause the EML to come on yes as it can when fitting HFC's.

 

You can get spacers though which are cheap enough and from what I hear do fix the problem in most cases.

 

I fitted HFC's to my Zed and the EML came on not too long afterwards ~ I just kept doing the pedal dance (ECU reset) to turn it off though after I had the code read to check it was just the HFC's causing the problem. Eventually though I had it turned off for good when I had my UpRev done.

So might be worth getting some spacers as well then. Do these fit between the manifold and the decat or the decat and the Y pice? ?

 

Sorry, I'm not that knowledgable about exhausts lol

 

I do have a code reader to clear the code if it does come up. Just as long as it's not causing any damage.

I'm looking at getting the UpRev done in the near future anyway. So this could be turned off at that point by H-dev or abbey?

Yep it was Horsham Developments that sorted mine out for me when they did my UpRev.

 

Fyi the spacers go between the 02 sensors and the de-CAT's. Like the below picture although the picture is of an 02 spacer on a Subaru Forester with de-CAT's.

 

 

Edit: Also some de-CATs and HFC's do come with a sort of built in spacer. Like below;

Cheers mate, that's great info.

Shameless pic whoring here, but you get the mother of all spacers built in on the Fast Intentions HFC

^^ Nobody likes a show of Chris.

 

Although who could blame you.

I had to do this recently. the spacers didn't get rid of the EML so I had it deleted down @ my Mates garage. It hasn't come back

Yeah as I said in most cases the spacers work but for some (like you) it hasn't. Good though that you got it sorted.

 

Nuisance seeing that darn yellow light lit up on the dash ~ even though I knew why it was lit up it was still a downer seeing it lit up every time I started the car.

Don't you need a special tool to remove the O2 sensor or what's the easiest way around removing it? ?

A spanner?!

 

Seriously as far as I know you just need the correct size spanner. Never heard of any specialist tool being needed but happy to be corrected if anyone else knows better.

[Rock_Steady]

yeah. I hated turning the key to see it there, staring me in the face. Glad it's gone.

Haha I'm obviously thinking about something else there. I'll try fitting them myself when I get some.
