Not Dyno, Just tune ECU

Josblos

The box in the trunk was disconnected as well as the probes connected to the DPF. The sensors which are on the first catalyst are always connected as well as the EGR. I only asked the question whether other people had also unplugged the EGR. The document provided is general for anyone who removes the DPF. Do you have to unplug the egr too? I do not know.

Ok I had the same done. But the document says to unplug the ERG and Swirl Flaps. I dont think that was done on mine.

Josblos

I found where the EGR is located but the socket seems well hidden for access

C300fan2

If you disconnect it please post instructions and location! Thanks

That document states to unplug the EGR, which will be under the hood. Look for it near/around/under the plastic intake manifold (driver side).

Josblos

I check them but it is not simple what is the plug.

do you put it back after?

Hey guys.

I got a notice in the mail that I need my airbags swapped. I’m just concerned if I took my car to the dealer and they plug their computer in they would revert my time back. Is this something that could happen. Should I be concerned about that.

thanks

J'ai fait faire cette réparation et je n'ai eu aucun problème. Par crainte, J'ai dit au gars du service de ne pas toucher a la programmation. Tout a bien été.

The recall should have nothing to do with the ecu tune. I doubt the dealer will spend an hr flash the ecu for u for free lol

andreigbs

Mine had the airbag recall AND the steering bolt recall work, two separate occasions, no issues with it being tuned (in other words, they don't check).

Now when they call you in for the "fix" that'll be a different story.

GLK Super Fan

QUOTEDo you have any issues after the steering bolt recall? Did they redo the alignment for you?

I am still debating if i should do the recall.

andreigbs

They did in fact check the alignment after the bolt was replaced, it was adjusted accordingly.

They also noted the RF tie rod has a bit of play and will need replacing. No charge on alignment, no other issues.

Is there any difference between the JR and Malone tune? The main thing I want to know is if the egr and swirl flaps get disabled on the JR tune. I am aware the Malone tune does disable the egr and swirl flaps. Also can you buy the buzzken pipe and use the Malone tune with it or the Rawtek pipe with the JR tune? Or, do you have to use the Rawtek pipe with the Malone tune and the buzzken pipe with the JR tune? I am asking because from what I see pictures of, the pipes that are available look identical to one another. if that is the case ill buy a pipe and pick out whatever tune I see that I would like to get. I just want clarification on this headache situation.

C300fan2

I dont think the Pipe matters at all. I just updated my software with a tune from OE Tuning. Running better, better MPG, and EGR is off like I wanted. Pretty easy to do yourself too. I needed to get a proper battery charger to do the update though. They recommend minimum 10A, but optimally 30A while you do the ECU update.

andreigbs

I made sure to hook up my Noco trickle charger before doing the reading/rewriting. I'm on the original 2014 battery, and I know it's weak. You don't want power issues while coding new software.

Also correct: it doesn't matter the brand of exhaust pipe. What matters is the tune. With the OETuning software, the car will still do regens when it thinks it needs them. If you remove hardware, you have to have a tune that stops any/all regens because without a DPF in place, you're likely to burn a hole in your new exhaust.

The best route, IMO, is to not need surgery on the car which isn't really reversible, whereas a tune is. Plus it's cheaper.

I want to install the pipe myself and have the ECU done by a shop, It is my understanding that you cant flash it yourself and need to remove the ECU and take it to a shop.

I am in Toronto, can anyone recommend a shop nearby?

C300fan2

That is not correct. OETuning sends you a module that reads your current ECU, sends the file to them, they modify it and send it back to you, you plug the module back into your car and It re programs the ECU. It is actually nice because the module will have both files on it and you can swap them if you want.

Josblos

Bonjour, dans mon cas, je suis de Québec et j'ai envoyé l'ECU directement chez Malone en Colombie-Britanique avec Fed-Ex. Au total, ca pris trois jours et je reposais l'ECU dans mon véhicule. Tout a bien fonctionné et j'aime le tunning Malone. stage 1.

Best option by FAR! Especially for those of us who will be switching back to stock in order to take advantage of MB's emissions fix and extended warranty.

Again, my condolences to our Cannuck members...

ramo80

are you guys keeping your cars modified or will you get it unmodified by the dealer since they are replacing all emission items as part of the recall.

artim808

You can’t go to dealer with modification for emission recall. They will refuse to do recall if you have any emissions related modifications

ramo80

I think many of us just did the programming change. At least I did. I didn't remove the DPF or modify my exhaust. Everything is as it was from the dealer except for the programming and the unplugging of the AdBlue Module. I can easily go back to the guy who programmed it and have him return it to factory programming. I mean I know as part of the recall Mercedes will install their own new software upgrade so i don't know if i need to go back to the guy or not. 4 years of warranty and a couple of grand don't seem like a bad deal to be honest.
