Hi you need to either flash dash or do both EPROM and ezs otherwise mileage will jump straight back up

Hi to all.
I record the dump to 24c128 and working 2 second. Now have the previoun value :(
I removed the EZS, is a W204 from Termic. I searched what MCU uses. I read that can?t read, is true?
How I can modify?
Is necessary modify other eeprom or flash? What?
Thank and Sorry so many questions.

I think the first thing that you need to do is confirm what type of Mercedes you are working on ? in post number one we are told you have a 2005 car ? then in post 10 we get more detail of car. First of all a W204 was not made in 2005.
Now that you have told us what the car is, you either need to flash the dash or fit a Can Blocker.
You won't be charging enough to buy a Can Blocker and you won't have a machine capable of flashing the dash to stop theEZS writing back, so your best option will be to give the car back to your customer and tell him you can't do it.

Hello to all.

Dashradio, you're right. I was wrong about the year of the car. But it was not my intention, because it does not benefit from it.
I have to say that, this is not my work is my hobby.
Before you ask all of you trying to find information to do twice the same question, and if I do beg your pardon.
Thanks to those who have answered me, I learned what is the "W204". If I know how complicated it was would not have taken the car.
We often do not provide all the information, but often do not know all the information.
Thanks again to all who have lost a little of your time in answering me and teach me.
Best Regards
