Tue, 18 Jun 2024 06:28:07 +0000Must also help the bigger secondary CAT's too. What am I doing to my motor. Ed in San Jose '97 540i 6 speed aspensilber over aubergine leather. 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). This heats the CAT's up quicker along with the pre-CAT O2 sensors. Zarboz, have you done this to your 540 yet? Some emissions issues at all? I like to pretend I know stuff. Lean warm-up: Default selection KFLMSKH with 1, 05, transition to 1, 0 resp. Euro byte for Secondary Air pump = 0. If you don't it will ruin the cats. Last edited by zarboz; 04-26-2019 at 07:21 PM. Is this PURELY for emissions purposes? Airlift 3H/P management, M5 steering box, M5 LSD, Eibach/Dinan front and rear anti roll bars, PM Modifich door boards, 4 Eton 6.

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. I have been driving with the relay removed for 4-5 years. Your not that far from Pikes Peak, take it up there and let it sit for a few hours and see how it starts. Cold startup fuel enrichment is separate from Cat-preheating enrichment. With the normal A/F about the only negative I can think of other than possible CAT issues would be the back sides of the exhaust valves may get more carbon deposits on them. 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. 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. When starting a cold engine, especially in the winter, on a leaner A/F mixture it won't run that well until it warms up. 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.

CWKONABG Altering from 5>1 is required (Explanation below). So zarboz must turn off the EXTRA richness for the SAP. It has been working flawlessly for 4 years now. "0:no secondary air system, lean catalyst heating operation of the engine | 1: with secondary air system, rich catalyst heating operation of the engine ". Long explanation below the TLDR is here: MSLUB and MSLBAS are expected return values for the SAP pump CWKONABG tells the car that the SAP is not installed and to treat the kats differently the CLA* items silence the check engine light because the pump is unplugged. Thanks for that Danny / Jim. SO I had to 00 out other items in order to get the SAP system to truly be "deleted" from the cars ecu functions. The SAP is pretty much there to please the emissions people, that's why plenty of countries don't have em. Maybe some on the tops of the pistons too. To get my SAP code to not be thrown on the dash anymore I did the following: This yielded me no error for SAP activation (it is unplugged and block plated off now) and I get no error after cold start for SAP. 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.Secondary Air Pump Delete E46 1
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. Some catalyst warming function during cold start. 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. Richer dependent on load (rl) when starting from rest and adjustment to the lean performance limit (lalgm) from%ESWL, as described in%LAMKO. I simply unplug the relay to the SAP air pump. You get to lose some weight, remove a few potential sources of vacuum leaks, simplify the engine bay, and you don't have to hear a pump whining on every cold start.

The SAP helps burn the rich mixture that is used during a cold start. 1, 2 x 10" Kove audio subs, Alpine ICS X7 Headunit, 19" BBS Hammer Sports RT245/RT246, Muffler delete, electric coolant fan. 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? The base point distribution of KFLMSKH, KFLASKH is to be chosen such that the "catalyst heating idle range" is sufficiently covered with regard to engine speed and load at idle and that a steady transition by interpolation to partial load can be performed. Well I did the SAP delete on my 97-528 using a kit from someone here.

OK so you're probably wondering whats going on right? Give it a try and report back, of course it's now getting warm so it might work pretty OK. 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. 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. The engine runs EXTRA rich when the SAP runs so that the unburnt fuel can be burnt in the cat with the air from the SAP. Codeword for secondary air system. I also deleted my SAP using a kit I bought from here. If you ONLY disable the SAP in the ESKONF file and make no changes to the cat heater operations the car stalls out on first cold start of the day. I don't see any cold start problems but as my car has a jag charger now and has had some fuelling changes I don't know how that has changed things.

I figure I throw it on here for someone who interests in this mod. Or Lambda engine default selection by code word CWSLS in%SLS analogues to lean warm-up. Sounds like a win/win to me. Yes, it's an emission thing.
Glad I don't have one! Takes a little extra key turn to get her on. The goal is to get the cats to work ASAP. This the kind of kit that connects to the 02 sensors I bought this simulator from a vendor here at bimmer. 1999 540 Auto with Eaton M112 supercharger.
