UK ECU tuning - m1tch - 07-30-2015
Hi all,
Just wondering if anyone knew where in the UK would be best to get my E300 ECU tuned, it seems that most of them are in the US and I haven't found any in the UK - most tuners only touch the CDI rather than the OM606 engines.
Can anyone help me on this

The ecu needs to get socketted.
Most people dont get involved cause its time consuming.
But mapping is not an issue .
Ive a lad in ireland who maps my edc ecu.
But i socketted it myself and its a pita.

That's what I mean - do you have any contact details for them? I have a spare ECU (I am aware that they are locked to the car but I figured I might be able to use the ECU and socket the chip) - is there no way to reflash them at all or does the chip need removing before reflashing?

They go under WWW.tdr.ie
You can't flash these ECUs.
But you will need to sort out the immobiliser on your spare ecu. To get it to work or de immo

Thanks for that, I will get in contact with them - I bought the spare ECU to possibly be cloned so I had a spare in case I had any issues with the stock one.

I know when i de immo my ecu. i just had to rewrite one chip to suit the cr1 immo delete..
You may be able to do the same to make your spare ecu by writing the working ecu code across.

What software did you need to read the original ECU code? Does it need to be removed and socketed before it can be read? I am tempted to get the spare ECU socketed and then simply read the code from the original ECU and then reflash the spare.

I hope you find the answers to your questions. I plan on running the MB ecu in my F150 swap with immo intact for security and as many of the necessary modules as possible for speedometer,cruise control,etc. I've been spoiled with my TDI's seeing everything in VCDS with my Ross Tech cable and software. Has any OBD port accessible software been developed and available for the W210 MB Bosch ecu and other modules?

I think the issue is that it uses a DAS system, the ECU is locked to the car's VIN after around 50 starts of the car, its also locked into the TCU as well for the gearbox, might be easier for you to run an OM603 mechanical pump and avoid the ECU - its a real faff to try and sort out as I have a feeling only the STARS system can read it. I will keep this thread updated if I do find something though, but I have a feeling that the chip needs to be resocketed with a different reflashable chip and copy over the OEM coding etc.

You're right, there is a DAS system. The key provides a code which the ECU is looking for. The code changes each time, I think but both key and ECU have the same algorithm to calculate it.
I've bypassed the DAS on mine and it works fine with the electronic pump. I took it to a guy who soldered in a tiny little emulator board. He then sets the ECU into "new key" mode which means it is waiting to learn a code from a replacement key. When the ECU is powered up, the emulator provides the code to the ECU which allows the engine to start. No fancy Merc key required. Works great! Occasionally, it seems that the emulator isn't fast enough or something and I can hear a clunk from the pump area when I turn on the ignition. When I hear the clunk, I know it won't start, so just turn the key off and on again and all is well.
I have a manual gearbox so don't know if there would be any impact on the Transmission computer.
