FAQ EDC Pumps / W202/W210 W463 ECU’s
As this is a community that i have learned so much from. I will try answer the most commonly asked questions and even some questions not asked but to give some knowledge back so people can better understand for their own projects.

FAQ
What pumps and injection quantity can EDC achieve?
The stock 6mm edc pump can put out about 90cc at the rack limiter, All 5 and 6 cylinder edc pumps can also be upgraded with dieselmeken 7,5 and 8mm elements, giving upto 170cc with reduced.
What power levels are possible with either?
Some power figures quoted for a stock 6mm edc pump are 250hp(om605) and 300hp(om606) these are realistic figures although i would not suggest building a car to stay at this level for long period of time. These levels of power are fine for daily driving blasts and fun etc. But if your racing or drifting i suggest get the larger elements fitted and this will help reduce injection time along with egt, larger element are sufficient for around 380hp(om605) 450hp(om606) these need to be confirmed by dyno.
Can the engine run standalone?
The stock ecus can be remapped to run completely standalone like in a swap just requiring minimal sensors and 2 wires for power along with common ground.
When running the ecu standalone the immobiliser needs to be removed, this requires a CR1 deimmo fitted and a small 24c04 chip to be reprogrammed to suit.
The absolute minimum wires needed is listed below

What are the minimum sensors needed to run the engine?
The engine can run on just a few sensor these include, crank sensor (CPS), Coolant (ECT), intake air(IAT), map sensor(MAP), throttle position sensor(TPS), Glow Plug relay, EDC pump. Most of these sensors are already fitted to the engine excluding MAP,TPS and IAT and glow plug relay.

Can i remove emission hardware like egr and airflow meter?
The ecu if used in a w202/210/463 can have limp modes for airflow meter and everything egr related removed, these would already be removed if using the ecu standalone.
What other changes to the stock ecu can be done?
Some additional functions the stock ecu can do along with altering fuel levels at various points to reduce smoke outpout and raise power output it is possible alter the stock rev limit from 5400rpm to whatever the engine can handle and introduce a hard rev limit upto this point. The map sensor can also be rescaled from stock 1.65Bar to 2.4Bar and even 4Bar sensors this is only needed with larger elements.
The throttle pedal can be rescaled to give more on-boost fuel control and make it more sensitive or less sensitive to use, as opposed to nearly 70% of the stock pedal controlling off-boost fuel in the stock setup.
50-75psi(a) pressure sensor that can be used to improve resolution with larger elements.

What will stage 1 give me?
Stage 1 on an om605 is rated at 180hp, om606 220hp. Stage 1 keeps the car ready for NCT/DOE/MOT vehicle testing with low smoke output and stock rev limit, there is a lot more to give after this map as it is very conservative to what is possible.
The w463 has more low/mid range power from stock than a w210 so w210 stage 1 will also have this improvement over a w463 remap.
Can i remap my ecu again ?
A socketted ecu can be remapped by fitting two new chips using a chip removal tool, unlike a petrol engine that needs rolling road tuning for fuel A/F and ignition timing, These simple map changes can alter the fuel at different point depending on your end goal easily.

What turbo upgrades are possible?
Using the stock 6mm elements on an om605 engine, swapping to a k14(om606) turbo is possible if your car is LHD, otherwise some very good results have been found using he221w, gt2871 and some testing is being done with a t04e turbo, also on stock elements for an om606 a gt3071/gt3576 or holset hy35/hx35 are some options available.
All of these upgraded turbos other than the k14 require a manifold or manifold adapter , custom intercooler pipes and new oil lines fitted. Along with improvements to the exhaust and intercooler.
Using larger elements is possible with all of the above turbo but larger turbos also become possible giving higher boost levels along with higher rev limits.
Can i get a spare ecu for my car?
There are a few options to tuning edc cars. You can get your stock ecu modified or use a replacement. The replacement ecu used has to be a facelift ecu if used in a facelift vehicle (one using the electronic key system, touch start) or any ecu will do in a pre-facelift once it is a matching 5 or 6 cylinder ecu for the engine, this is then fitted with a CR1 deimmobiliser and will work in your car.
Another alternative is code the immobiliser of a new ecu to your car using something like STAR DIAG, or make a copy of your stock ecus immobiliser and program that information to the new ecu.
Either solution gives you a spare ecu to use as an alternative.
How do i remap my ecu myself?
In an ideal world you have already done it before or are very good at soldering. I have had to replace a fair amount of ecus due to damage recently due to using too much heat and damaging the chips or surrounding chips along with forcing the chips off the board and damaging the tabs that they solder to. Both situations make the ecu non-repairable or beyond repair.
A hot air station can be used or CHIP-QUIK to remove the stock chips, a fine tip and steady hand is also needed to solder the two plcc32 sockets in place. Using alcohol to clean the surface and flux before and after to help the solder flow.
The same goes for the immobiliser chip this is a small soic8 chip so care is needed to remove and resolder this, a programmer is also needed to make changes to this chip.

No doubt some of these figure are incorrect so if anyone else has any input i will amend the post. As i get more feedback i will also update the post with results from people.
