Map needs adjusting. Its only a few values within the minu wont take your mapper more than 10 minutesokay cool! good that i don't need to pay the price of a new map. Will it work with the lambda cutted off if i install the cat for MOT again?

No need to cut lambda off. Can leave both installed. Primary lambda will be fine with a cat fitted for MOT purposesso it will work fine after the lambda is coded out for the de-cat to work fine? and no coding needed when re-fitting cat for MOT?

If the map (emissions threshold) is adjusted correctly, you won't get an EML with the de-cat. The primary fuelling lambda is unaffected so it will be fine, and you will be fine to re-fit the cat for the MOTNo need to cut lambda off. Can leave both installed. Primary lambda will be fine with a cat fitted for MOT purposesso it will work fine after the lambda is coded out for the de-cat to work fine? and no coding needed when re-fitting cat for MOT?
A friend to me told me its possible to pass mot without cat. True?

No. It will fail on a visual inspection (as it is missing) and it will also fail on the emissions. It will not pass a legitimate MOT with a de-cat fitted

To stop the EML coming on the map will need adjusting to change the cat efficiency threshold map. This is still a map adjustment but is more of a patch to the software already on there, it will not affect the running of the car in any way
There are two lambda sensors, one before the cat, and one after. The one before is the primary fuelling lambda. The second one (after the cat) is simply there to monitor the efficiency of the cat and is the cause of the EML when fitting a decat. The adjustment to the map changes the threshold that triggers the EML (or they simply remove the DTC all together - either way)
And yes I have a decat and Revo software (Stage 2+)

To get the most from the car, the map will need adjusting to take advantage of the increased flow potential, but it is not essential. This could be some adjusting to your existing map or a whole new one - talk to your tunerWhat arw the gains when fitting a de-cat? And it will be fine when re-fitting old cat for MOT?

It will be fine if you drive it normally/off boost, but I wouldn't advise hooning it all the way there, and hooning it all the way back

Impossible to put numbers on it, depends on whether you're K03 or K04, the mapping, stage of tune/other hardware fitted etc. It will definitely open up the higher RPM though regardless. Have a read of the TFSI stuff on Niki's site - covers various stages of tuning and gains: http://r-techperformance.co.uk/ (make sure you look at the right sections for K03 and K04)So i should not hooning when the oem cat is fitted with the lambda coded etc? But can hoon when de-cat is in place?

Lambda spacer can be used to try and avoid the EML if you don't get the map sorted. Of you have the map adjusted then they're not needed
Post by: K9 on December 07, 2015, 06:08:11 pm
Correct, sensible driving with the cat fitted if youve had the map tailored for a decatcool! any good place to order a lambda spacer from? i guess it don't hurt to use the spacer and tweak the custom map? Btw should i install a CAI or a good ( K&N panel drop-in filter ) ?

If it comes on, get the mapper to map it out so you dont get EML.
If your map is to suit a car with a cat in place, then you remove cat and only have map tweaked to rid the EML, then you put cat back on for MOT- you can still drive it hard as it was mapped with a cat anyway.
Only time you couldnt drive it hard with cat fitted is if its been mapped without one (and itll have smaller downpipe than a decat).
The rear lambda which you get mapped out is not important, its there to make sure the cat is doing its job, hence why it pops a EML when you remove cat. The front lambda is the one controlling the fuelling.

Fit a decat and see if your EML even comes on, it may already be disabled in your current map file.Great info m8! Will install the de-cat myself and see if i get the EML or not. how much can a tuner charge to tweak the map?

Hi Dan, some people like to wrap and some don't, why would you not advice it, anno ceramic coating would be best...

I get you dont have to but you can get easier access to the top of the downpipe bolts by reaching over the engine

It depends on whether you are having the map tweaked for performance, or whether you simply want the Lambda fault patched out. Since you haven't named the tuner, I would hazard a guess that most will want between £50-100 for doing it, but you're at the mercy of your chosen tuner really.i got a reply from my tuner and he told me they need somekind of hex address to de-activate it and they don't have it on there custom map? Can i try to cheat the EML light with a spacer and bounch of wire wool stoffed inside the spacers end? and if the light comes on can i still drive with it normaly? mo defects?

The spacer is the next option as mentioned. You can try wrap a gauze or wire wool to fool the cat into thinking the cat is still there and preventing gases from triggering the sensors eml off so easily. It's a cheap mod so worth the pennies.Any ideas how to "cheat" the lambda sensor without mapped out?No because I didn't want the wire wool to get sucked further back into the silencer and block itI've tried the spacer and it doesn't work for very long and the eml keeps popping up here and there so I have a hand held diag tool on the car to delete this. lolTried with wire wool?
