W210 ECU Conversion (DSL1)
W210 ECU Conversion (DSL1)
I'm considering getting my hands on a DSL1 controller and manual/trans controller. I currently own a 1997 and a 1998 w210 e300 and was wondering how the car would react to not the OG ecu. The 97 has the older switchblade key-type system and the 98 has the newer type. I'm concerned about systems like ignition, ABS, ASR, SRS, climate etc.
Is it possible?
I figured this topic could probably use its own topic and Baldur please chime in if you know.

The safe way to approach this is to leave the ECU in place and only remove its connections to the sensors and actuators on the engine.
But people have converted W210s to use mechanical pumps, maybe they can chime in on what functions were lost in the process, then I can evaluate what needs to be done to regain those functions.

I can't really say as I haven't tried running a W210 without the ECU in place.

The cruise control would go if you go with a mechanical pump, the fuel stop solenoid on the side of the pump needs the ECU to allow it to unlock (although you can bypass it), also if using the OEM turbo, the vacuum transducer works via the ECU as well so you would need to convert that to a pressure wastegate. I think other functions like ABS/SRS etc might also stop working but I am guessing that the DSL1 controller would get round that by emulating the ECU (which is locked to the cars VIN) - let me know how it goes as I will be looking to run the same combo as you at some point.
It had a 722.6 stock but now has a 5 speed manual.
Note that if you wan't the tach AND more importantly coolant temperature gauge to work the ecu must stay there !! The sensors are used by the ecu and then the information is sent via CAN to the instrument cluster.
I have a W202 that was converted to a mechanical pump by the previous owner. The ECU was left in place and everything seems to work in the car except:Tachometer- a flywheel without the trigger pins was installed so there is no rpm signal, ASR doesn't work of course, ABS works fine. Also AC doesn't seem to work but i suspect it is due to the lack of rpm signal. I have no idea why the PO did the conversion.

I've looked into this, and disconnected the EDC IP and turned the ignition on to see what would happen (just the above 2 warning lights).
Installed:
OM606/722.6, big IC, W220 brakes.
Planned:
DIY manifold, compound, 722.6 controller, built IP.

Leave the ECU in place so the key and clocks work. You'll need to remove the bulbs in the cluster behind the BAS & ASR warning lamps because they'll be on.

I've read this a lot on the internet and that the ECU is somehow configured to only work in one chassis and it's confusing and not true.
It is true that you can't take an ECU from one car, plug it into another and start the engine. That is not because of the chassis, or the VIN stamped on it though. The ECU does require a correct code in order to allow the engine to start. This code comes from the key & ignition module, not from the chassis or VIN. So, as long as your ECU is getting the correct code, it couldn't give less of a sh1te what VIN is stamped on the chassis or whether or not it's connected to any chassis at all for that manner.

(02-01-2016, 05:34 PM)Petar Question: When you swap the engine ECU do you have to swap any other controll units ?
Or just the key and ecu ?
I have a couple of ECUs with the DAS (Driver Authenticaation System) bypassed on them. I can take one of these and put it into any W210 with an OM606 and it will run just fine. So, the only dependency I've come across that would apply to an unmodified ECU is that whatever car it is installed in would need the key and ignition module from its original vehicle.
