very rare that both o2 goes bad at the same time.... must be tune related

Stile

Could it be? I do exactly the same thing. Just got my new ECU flash tune from the EC.

Hulk

Can you guys get to a star das system and you can shut off the rear O2s

nafania

I have read about it and i tried. But i believe once we got the screen we couldn't find the item #183.
is it 183? Also once we got to the implizite codierung all the fields were -----(dashes) but the car was not running. i also read somewhere that it should be running once you do the codding. Is that correct?

Hulk

Yes running
Some cars do it with just key to position 2

nafania

Thanks HULK.
Well mine didn't.
My car is at the shop now, but next week i hope i will get into that.
Once again Thank You.

Do a quick test and deleted all codes on the car and then right after doing that go into dev menu

nafania

Got it.
Thank You, Sir!

if there is any code current or non current stored in the ECU none of the fields will be populated in the dev menu

nafania

quick test. clear all code. ECU must be error code free. Fire up the car and into dev menu.

Once i am there should i turn off EGR and Secondary Air Injection also?

EGR #0176
Secondary Air Injection #178
Post Cat 02 sensors #0182

Are those correct fields?

From pacougar and works

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

So is there a difference between the O2's being disabled in STAR versus in the tune?

Rob CL

Really, it should be the same. The monitoring code is just switched off. Basically the same option Diablosport made available to earlier SRT8 models.

I had my mids installed a couple months back, and I'm loving them. Only running headers, tune and EC H/E, and there's a HUGE difference vs stock. I have a pulley laying around, but I want to get a few good passes on this setup before upping the boost.

Some of you may have already seen this, but here's a half-assed video of the difference in exhaust notes.

nafania

Thank You Hulk. Appreciate your time. Next week i am scheduled for some Star coding. Hopefully this o2 sensors error will be solved.

recently got EC mid length headers installed. looked under the car and noticed the shop didnt install the o2 sensors back in. none of them. not even o2 bungs for the secondarys. will retune turn off all sensors? im waiting to hear back from EC

E55AMGGG04

Have them install all 4 sensors.

Clean install, LNDMISL!

Can I ask why you wanted to have those short flexes installed? I don't believe our cars have any flexes from the factory in that location..

Also, Is your car completely stock aside from the header installation? I'm asking simply because I ordered a set from the guys here in Toronto and they should be arriving next tuesday/wednesday so that I can install them.

In your honest opinion, do they make a decent power gain? Have you had Eurocharged tune the car for the headers? Any more gains after that?

Just a curious fellow GTA buddy.

thanks,
PMG

Flexes are to handle the stress of engine torquing itself and rotating against driveline, and the flexes relieve the stress instead of it eventually cracking the aftermarket headers.

Stock car doesn't have them because the oem logs are very short and can't put the same leverage that longer headers do (plus they are cast, and just stronger than aftermarket headers).

pmgiarrizzo

Yes, I agree flexes are used for those intentions, I was merely curious as to why he seems to be the only one who has placed them there. I haven't seen any other header installer (with pictures posted) that show any signs of flex joints. I mean, good idea and all, but is it necessary?

HeissRod

Flex pipes are not a new thing around here

Rob CL

Missing cats aside, flex pipe is illegal in several states. Just a thought!

HeissRod

I've never heard of this. Educate me!

speedyc43

Let me know how you like the headers, Im also a customer of Eurocharged here in Toronto

Rob CL

In my state (and others, not sure if it's a federal law that's not enforced) if you fit flex pipe on a factory exhaust that didn't include one or more, you'll fail visual inspection.

Not being a nanny, just been down that road before!
