Ecu Development om605/6 - seanyt - 03-22-2016
Been at this quietly for a while now.
But i now have a selection of om605 and om606 ecus ready.
with deimmobilisers for conversions and also to swap into w202 and w210 vehicles.
The final piece of the puzzle has been the rev limit, ive been working on this for a while and should have good news of a custom rev limit soon
At present i have stage 1 tunes 180hp for om605 and 220hp for om606 both with egr removed.
i also have far more aggressive maps that can max out the stock 6mm pumps.(suited for turbo upgrades only)
My own car has a 8mm pump fitted and an ecu map also to give it minimal smoke but excellent power and response.
The same can be done for another other vehicle with 8mm edc pumps fitted.
The benefit of these is a solution to tuning your own car and not needing to buy the increasingly costly mechanical pumps.
The car also requires no modifications unlike fitting a mechanical pump, other than removing one connector from the das system.
This means ecus can be sent out as spares and also sold among members without dealing with immo issues, further remaps can also be sent in the post with a removal tool
if changing turbo or fuel pump or any other mods.
RE: Ecu Development om605/6 - seanyt - 03-22-2016
The only model i have run into some problems with are facelift w202 and w210 with a newer style das system.
These can also be tuned in the same manner but require facelift ecus to work with the system.
I have some w210 facelift ecus but no w202 so an ecu would need to be supplied for this.
I have also been working on a simple canbus box that receives the ecu variables like tacho , engine light, glow light and outputs these to custom clocks ideal for a conversion and reducing
the need for running additional wiring or systems, i can post details up about this with code for people to play with.
The price for each ecu supplied is €350 plus shipping worldwide, if i receive an ecu to work on it is €300.
Remaps can be sent in the post at a small additional charge.
all ecus are tested before i send them out.

Very cool.
On the CAN bus for outputs Lingenfelter Performance already has a great product for this. All you need to do is put in the CAN data and output structure. They are pretty cheap. Retail is around 250.00 if I remember. I have used a couple for all sorts of things.
RE: Ecu Development om605/6 - seanyt - 03-22-2016
The solution I'm using at present is about €20 but more for a specific use. Rather than a open source unit.
I have seen them alright and have friends who have used them for aftermarket alarms. They are easy to setup.
RE: Ecu Development om605/6 - whipplem104 - 03-22-2016
Cool.
Yeah you can do it a lot cheaper if you do not have to do software with it.
Up to what year and CAN system are you able to do the ecu for? I do not know in Europe when they stopped making these. Did the om606 ever come with the 312 id structure with egs52? Should be around 2001-2002 when they switched. Gas cars I see with ME2.8 with egs51 still sometimes. Odd cars though like 4matic wagons.
RE: Ecu Development om605/6 - seanyt - 03-22-2016
Latest e300td I've seen are 99. Probably still egs51.
I do know someone who was able to get the stock egs51 working connected to the stock ecu and just feeding it two canbus packets containing wheel speed and a brake signal byte also.
What's 312id structure?
RE: Ecu Development om605/6 - seanyt - 03-22-2016
The clocks and ecu are on the same bus. So I'd imagine all w210 w202 clocks use the same can ids to drive the clocks.
RE: Ecu Development om605/6 - whipplem104 - 03-22-2016
Early cars use 310 id from the ecu and later ones use 312. Mainly torque is in this. Also a few other things are moved around and there is a lot more data from the tcu.
RE: Ecu Development om605/6 - seanyt - 03-23-2016
I guess that rules egs52 out then. 310id is definitely there but nothing on 312id
RE: Ecu Development om605/6 - Hario' - 03-23-2016
Hello
My understanding is the key / ignition switch barrel and ECU are all coded together.
Is the necessity to match the key / ignition switch and ECU part of your immobiliser fix?
So your random ECU will work with my random car key / ign. barrel?
Cheers, H.
RE: Ecu Development om605/6 - seanyt - 03-23-2016
Hi
there is no need to code or match anything with the ecu is send,
anything prefacelift i supply an ecu and you remove the canbus connector from the das and it start and runs with out any immobiliser issues.
On facelift models you also remove the canbus wire from the ignition switch and once it is a facelift ecu supplied it will work off the key, a prefacelift ecu in a facelift model will also work but starter will not turn off the key.
your only removing the canbus wires so there is not a immobiliser conflict, thats why these ecus are also ideal for conversions. you run the minimum amount of wiring to the ecu 2 power wires and 1 common ground gets you going.
RE: Ecu Development om605/6 - whipplem104 - 03-23-2016
So how do you start the car if the EIS is not on the CAN bus. The start message is on the CAN. Also you mean facelift by when they switched from DAS2 to DAS3? mechanical key with imobilizer ring to Smart key?
RE: Ecu Development om605/6 - seanyt - 03-23-2016
The eis authorises the existing key and sends a signal to the starter.
Your just removing the immobiliser conflict. Its worked on plenty of cars so far. But you need a facelift ecu.
pre-facelift ecus will also still work but the engine starter will not work from the key(eis).
RE: Ecu Development om605/6 - whipplem104 - 03-23-2016
Interesting. I believe you that it works, I am just not sure I understand. The EIS has the hash output and then it has the Start message. THey are on the same BUS just different ID. What is the conflict? I would assume there is an issue with the HASH going out and not being accepted by the ECU on the response for unlock? I would think that you have to put a specific filter on the BUS for this.
So if you just send the start message to the ecu from a CAN message will tip start work in a standalone function. If so very cool. What about neutral safety without the TCU for swaps. Or does it need the Neutral safety message as well?
RE: Ecu Development om605/6 - seanyt - 03-23-2016
Its working fine in my own car without any need for connection to anything else. I have full power and no limp.
My understanding is that the starter is on the canbus but is triggered separately from the eis.
when the ecu is unlocked from the deimmo it sends out a message to the starter on the bus allowing it to turn over.
otherwise removing the canbus wiring from the eis would not give this start message to the starter so it has to be coming from somewhere else.
Thats why if the starter is triggered and not from the eis on a facelift model with the prefacelift ecu it will still run as the ecu is given power and unlocked.
RE: Ecu Development om605/6 - whipplem104 - 03-23-2016
I will have to look at the wiring and function schematics. It must be different than the other cars. I wonder if it still uses the SAM module in the driver's fuse box and it is hard wired some how. I do not look at early stuff very much as I am mostly working with newer cars.
RE: Ecu Development om605/6 - whipplem104 - 03-23-2016
I looked it is actually hard wired from the EIS. This is different than later cars. Very cool that you can do this. Would be interesting to do this on Gasoline engines as well. ME2.0 cars with the M104, M120, M119 etc. Should be the same architecture.
RE: Ecu Development om605/6 - seanyt - 03-23-2016
The deimmo is available for some m104 and m113 ecus and also some early cdi engines.
I'm guessing once you go w211 and w203 its wired differently.
RE: Ecu Development om605/6 - whipplem104 - 03-23-2016
Oh yeah. It is in the code somewhere. I have been working on this for several years on later stuff. I am working on a different path now to possibly emulate but most likely just do coded sets with EIS, ECU, keys and ESL emulator.
RE: Ecu Development om605/6 - AlanMcR - 03-24-2016
I'm impressed! Now get this to work on a OM651, I would dearly love to get one working stand-alone.
RE: Ecu Development om605/6 - charlysays - 03-26-2016
I've got one of Seans Deimmo Socketed ECUs in my daily driver... a 240k mile C250 TD auto 1998. Currently running 180hp chips.
All you do is unplug the two canbus wires from the back of the EIS ignition barrel and it works as normal... tried the same ECU in my project C250 and it's fine in there too once the canbus is off the EIS
Got another one coming from him next week for my other C250 (which I've got a GT2871 to fit to it to aim for 230hp).
Considering a superchip costs £350 (and is soldered to your coded ECU) seans ECUs are a wicked C250/ E300TD budget tuning solution.
I've got a silly map from sean too, which will max out the stock turbo so i'll maybe try that gingerly next week
