Hi all

I have an E220D and am considering a custom remap (rolling road) and am curious whether anyone has had this done on their own car and whether you have had any issues afterwards? Long term reviews welcomed!

The car is heavy so I really think the extra 80nm torque which has been quoted will make a difference, I'm assuming the extra BHP will be more top end, its really the torque that I need.

Am I right in saying that the engine, tranny, injectors etc. are all the same as the E300d in the same year etc.?

I got my E400 remapped a few months back. Never had an issue with it so far. SHOULD be close to 400hp and 580nm but actual testing needs to be done. Car feels faster and definitely throws you back in the seat more plus I got 38.2mpg fool economy coming back from Newcastle

Being a 2021 vehicle Bosch actually locked all the ECUs back down so tuning wont be possible without further cost and having the ECU shipped abroad for unlock procedure. This is the case with BMW and Audi (VAG) Bosch found the loop holes being exploited on these newer MD1/MG1 ECUs and reapplied a lock

Many thanks

My local rolling road performance tuner has quoted me price and performance figures to do this, suggesting it isn’t locked down?

Not really a fan of remapping as you always read posts later down the line of knock on problem and some
mappers using cheap files.

Each to thier own mind.

If you can get it done and its what you want. Then go for it. do post back the results. .

GAD are pretty experienced in this, so I guess you'll find out if your local tuner is telling the truth when you get there.

I'm not sure the gearbox is the same. Mercedes use different internals depending on the torque rating the gearbox is expected to handle.
For example the 5 speed gearbox in a V8 SL500 is rated to 580Nm whereas the one in the V12 SL600 is rated to 900Nm even though both are nominally 722.6 gearboxes.

I don't know about the 220d vs the 300d but I would imagine the 300d is uprated.

Bflash is a tool that we have for communication, the tool Bflash is a side business to BR Performance, i have the tool so i have the option to ship the ECU to Bflash for them to perform the unlock at a price and can then tune them, the issue is a lot of people do not want to fork out the £500 extra to send the ECU off for a week and then pay after for the tuner to actually tune the vehicle

It worries me why they have not at least given you the heads up that most likely it cannot be done, personally that would suggest to me they dont have the knowledge or experience with these MDG1 versions of ECU

Lots of people say lots of things… and many promise the earth and deliver very little.
Good to hear your thoughts and advice as many on here have suffered with “maps” that don’t deliver and lead to warnings lights and poor running.
