Secondary Air Pump Delete E46

I actually planned on going up to the mountains this weekend hopefully its chilly enough to get a real life result from this change test to see how it impacts fuel on start in a real world application. Is this PURELY for emissions purposes? Switching off: No catalyst heating with MLSUS = 0 in%BBKHZ No Lambda action during lean warm-up: KFLMSKH = 1 with secondary air: MSLUB = 0 in%SLS and KFLASKH = 1. Secondary air pump delete e46 how to. I was speculating that this richness is purely during "warmup function" which i would imagine the SAP dumps air + Gas to the cats to get them up to operating temp as fast as possible in case of a cold start emissions test? I have sufficiently coded the SAP out of the DME portion via the 64kb mapping tables myself a I have talked with a few dudes online in Russia who are familiar with our DME and all 4 of them gave me different methodologies and reasonings why the other guy was missing X function or why Y function was important to 00 out as well it was pretty easy to figure out once i had some data sheets.

Secondary Air Pump Delete E46 How To

Long explanation below: By the bit B slsfz from CWKONABG the catalyst heating concept without / with secondary air system becomes compatible: B slsfz = | 0: no secondary air system, lean catalyst heating operation of the engine | 1: with secondary air system, rich catalyst heating operation of the engine Further possible secondary air variations are described in%SLS. I have been driving with the relay removed for 4-5 years. Maybe some on the tops of the pistons too. OK so you're probably wondering whats going on right? Euro byte for Secondary Air pump = 0.

Yes, it's an emission thing.

I was more just curious what negatives I am looking at other than emissions and slower catlyst warming on cold start due to leaner fuel conditions. 5s, Sound Magus VS3500. There's no real harm in deleting it if you block it off properly and code it out correctly (which plenty of reputable tuners like DUDMD will do as part of a tune). Sounds like a win/win to me. Please be forgiving I am not really a mechanicly minded person I work with computers all day so I get what the datasheet is saying that it aids in the warming of the catalysts via exhaust at a more rapid rate. NO cel no nothing, quiet as a mouse. Airlift 3H/P management, M5 steering box, M5 LSD, Eibach/Dinan front and rear anti roll bars, PM Modifich door boards, 4 Eton 6. Or Lambda engine default selection by code word CWSLS in%SLS analogues to lean warm-up. Codeword for secondary air system. Secondary air pump delete e46 parts. I also deleted my SAP using a kit I bought from here. So in my adventures of learning how to tune my car I wanted to track down DTC definitions (I have all of them I think) and that required some testing. Takes a little extra key turn to get her on.

1992 525i 5-speed - Thread. The SAP interacts with lambda tables and timers as well as interacting with catalyst heaters and heating function. If it is enabled then it injects more fuel during startup routine to make cats reach operating temp faster.. the really long technical looking snippet right before my inquiry is a snippet from the software data guide. They cannot handle that much extra fuel without air on short trips, maybe it will burn off on longer runs. The goal is to get the cats to work ASAP. Rich warm-up: Default selection KFLASKH with 1, 1 to 1, 2, transition to > 1, 3 when starting from rest and adjustment to the lean performance limit (lalgm) from%ESWL, as described in%LAMKO.
