Hi Guys,

What could be the explanation for line two on the label ? It says "6 Zyl.". Isn't that two cylinders short ?

If anyone could give me an answer it would be great.

Kind regards Lars Rasmussen

So weird, normally that do say 8 Zyl and that part number isn't listed that I can find in EPC for a C63, but it does start with the A 156 number so is for an M156 motorl.

Did find zip tuning references that number as a C63 ecu that they have a calibration for https://www.ziptuning.com/ecu-tuning...-tuning-files/

LARSLEMANS

Yes but the ECU hardware number ends differently in the ZIP tuning data.

Could the original ECU been changed at some point in the cars life ?

Very strange !

I found another chiptune for exactly the same ECU hardwarenumber here:

http://www.dyno-chiptuningfiles.com/...-392156-56846/

So it must be the right ECU, but with an error on the label.

ME9.7 is correct also, the 6 cyl on the label must be a typo as the others say 8 cyl some have AMG on the label and some don't - could have been replaced, could be a very early one as you have an early car and just had a typo they eventually fixed.

It was my bad was looking at 204.277 in EPC, you are an early car 204.077, so it is a the early ECU part number - first one in the list - very first ECU part number.

Hey Rob,

Eurocharged couldn't tune my ECU unless I sent it in, as they couldn't retrieve the stock file from MB. That first site looks like I can get the stock file for free? Is that correct?

Also how would I match have the data up - maybe it's just difficult cause it's on mobile...

roadkillrob

I have no idea about that first site just had a reference to your part number.

Not sure what you are asking about matching the data up?

Adi-Benz

(I'm not OP) The first site you linked says that they give out the stock tunes for free. I thought you might be familiar with the site. I see you directly grabbed the c63 # for the OP, I was just searching the previous page for c-class models and their ecu's. I think I figured it out, I'll have to look into it.

LARSLEMANS

Thanks for the explanation and for looking into the parts catalogue. Last time I counted, I fortunatelly still have 8 cylinders, so agreed it must be a typo.

Yes my car is an early model, and to be safe, I got my headbolts fixed last year.

roadkillrob

Is it really slow because the ECU can only fire 6 spark plugs . I would have to agree - just a funny typo probably from the first run of labels - maybe it will be worth something someday!
