Diagnose Secondary Air Injection, EGR, and Post Cat 02 Sensors through SDS
#51
I was looking around in here and I saw that the following were already diagnose aus in my car
180
186
And a few other things that were "aus" on the list. Anyone have a clue what those things are?

Correct me if i'm wrong - but that would be an insane "free" tuning possibility.

on some cars yes it may need to be running.
this is always worked for me.
Quick test > delete codes in all modules > then go and into ECU and turn of rear 02

What is the reason of disabling all of these
Currently my car is stock but am gearing it up for mods
Also in NZ we have absolutely NO emission laws what so ever......if you want to run open pipes etc, that's fine with us
, all we have is a noise limit to abide by ~100db and the exhaust has to exit the chassis
Would there be any benefit for me to go through star and disable all of these
I see you guys seem to be getting smoother idle and better low throttle response with them all disabled
Thanks

Does EuroCharged disable EGR in their tune? I cannot get EGR disabled. Every time I try, the change is never applied (although I had no trouble turning off SAI).
Also had problems with DAS showing invalid values in the variant coding. I was able to correctly see the values by not having engine running, and out key in position 2 (position just before cranking).

Cleared all faults
went to coding menu
disabled all 3 at once
applied setting
successful message
car running the whole time
Running fine today
A little richer on initial warmup
Idle seems smoother

Disclaimer: First of all this is for diagnostic purpose only!!! Second in most country's it's quite illegal to modify these on a road going vehicle, in fact in California it's illegal even if the vehicle is for off road purposes only. You should only use this to locate a problem and fix it.
You'll need a Dev mode SDS unit that's unlocked.
1. Select your car
2. Go to Control Units
3. Go to Drive
4. Go to MESFI 2.8
5. Go to Development Data
6. Go to Control Unit Adaptations
7. Go to Control Unit Adaptations(Variant Coding)
8. Go to Implizite Kodierung ME281 AMG C6-Stand
For EGR scroll down to 0176 and change Diagnose ein to Diagnose aus
For Secondary Air Injection scroll down to 0178 and change Diagnose ein Diagnose aus
For Post Cat 02 sensors scroll down to 0182 and change Diagnose ein Diagnose aus
That will disable each of those in the computer.

Going to meet a friend next week who has Development DAS.
Thanks.

No update here uh?
Friend of mine and I were able to change post-O2-sensors (0182) and SAI (0178) into "AUS". But... EGR (0176) kept poping back to "EIN" no matter what we tryed. Any help on this?
And one other thing too... Vmax (0224) there wasn't higher option than 250kph awaible. Why? Where I could switch 300kph?
Help please?
