325i, 3l, 3 stage manifold, remap with nox delete running stratified with a slightly broken nox sensor!
With 325i is no brainer to remap. 330I is marginal BHP improvement maybe 10-15bhp...
To really make it work and sound better with either NOXEM or Remap/NOX code out it would be best to remove the exhaust mid section with the Nox cat as both solutions are fooling the ecu in different ways..

So which would you advise/recommend Will? I've already deleted the secondary cats with the Direnza pipe as you advised!
NOxEM and Maptech NOx delete both cost about the same! Just not sure which method to go for (reliability, efficiency etc.)
Maptech charges £70 extra for a rolling map for the 330i which although don't add much I think it may improve the throttle response! |

Interesting, thats exactly what I want to do with my 330i (not much gain I know); code out the Nox sensor and remove secondary cats.
Where did you get yours remapped if you dont mind me asking? And did you get a before/after printout? |
If it was me I'd remap it, mid range response was allot better. But it's all subjective.. I'd also make sure I had some new plugs in and check my coil packs to make sure there in good shape .. ie no arcing marks discolouration etc |
Cheers for that! Has your mpg improved too? As most with NOxEM claim around 40mpg easy on steady runs?
Just trying to see if the remap makes the car as efficient as NOxEM! Specially as bimmerprof claims that NOxEM improves efficiency up-to 10% over a fully working OEM NOx system! |

Hallo. I have followed your discussion in this thread with high level of interest as I have become myself a victim of noxem marketing in May of this year and "enjoyed" the experience of claiming its failure (still think that it was originally very good product but when costs saving launched and production outsourced somewhere to people republic of xy it became a questionable and tricky piece of s....t). Now, I have back in the car but knowing many construction details, I do not dream about its lifetime and prepare myself for the remap/ nox system delete. As I checked in my country there are already few garages doing nox delete....but only version which allows the engine to run in homogenous mode (which is also not bad because emissions in this mode are apparently low compared to stratified charge....which was designed for fuel economy but its emissions ruin costly and fragile nox system ), but it seems that some of you have enjoyed remap which allows both homogenous and stratified modes. Can you please provide some details on the remap? Thank you |

Where and how are they claiming that?
