Helloo, I'm new to this forum and to chiptuning but I have read and watched some tutorials how to find maps and how to use Winols.
I have a 1997 Mercedes with legendary OM606 diesel engine.People are tuning this engine with mechanical parts and new non-electric injection pumps and get 500+hp. I would like to get more power out of my engine and disable some things.

At the moment I havent got my own eprom read, but i have some original files. People say that this ECU is quite easy, but for now I have looked it and I only can locate some potential maps, so maybe someone could help me out.

My goal is to remove the EGR - to get to know how its done. EGR solenoid and valve (same as turbo valve) are the main problems with this engine going to limp mode.
Increase Torque and I have heard that it is possible to disable MAF on this engine so I can easily install a bigger turbo to it. Original turbo is quite small.

Any help would be useful, thanks!

Here are the .ori files

I have searched for some maplocations over the internet and I have found some clues or even maps.

Maps in first codeblocks :
voltage 3D8D4
torque 3CF04 (20X1) ??
smoke 3D004
driver wish 3A000 ??
3AF7E would be EGR,
3CAB8 would be cranking IQ
3E7C0 would be requested boost
3EBA0 would be atmospheric pressure boost limiter
3E4B2 IQ limit fct t° - cant really get what this is, it something but the temperature is quite odd.

The ori. files, both HHH and LLL are here that this info is from.
(BTW why are there 2 chips and why are they called HHH and LLL, i read somewhere that it is low and high bite data, but why is it used?)

But i cant understand some things, like:
EGR - why is it only to ~3000 rpm and 30mg/stroke of fuel when the engine is capable of 5000? And MAF data looks a bit funny when the end peaks quite alot.
Are there any factor offsets to pump voltage or any other axis?

I understand that this ECU has 9 blocks of data. ECU number should be MSA 25.1 (some say that it is MSA 15.1)

Is it possible to change the MAP sensor to any other, like to a 3Bar map sensor that I could boost the engine a bit more and have a better turbo to it.
And what does the fuel temp sensor and Inlet air temperature sensor do with the ECU - any restrictions to fueling?

this are my maps.
I have a 1998 300TD , with Electronic pump, HX35 turbo, and sockets soldierd to my ECU board.No EGR, NO catalist
I have the WG valve on always vaccum possition, (baypass to provide vaccum to WG valve, to keep it closed at all time, when I connect it, it does not shut, computer does not send valve signal to lett vaccum thru since we changed the turbo, so I baypassed it), I have also a Map sensor from VW 0-3 bar presure (up to 2 bar boost). When I drive on soft ver 2, I keep getting overboost error and i have to shut engine off for 10 seconds, and restart. And it smokes alot. In ver 2 Air Mass flow sensor is supposedly turned off. Its not installed at all before turbo. I dont have intake , I want a K&N directly on turbo. I asked my guy to delete form soft air mass flow sensor.
since March 2016 when I payed the guy to put sockts on ECU, and remap chips, he couldnt supply me with stable soft that does not get errors and once works, and once does not.
ver 1 was once working boost up to 27 psi, and not working via overboost, I purchased mapsensor 4 bar(3bar boost), and tried it on , but with it connected there was permanent mapsensor error (0,9V on ignition, mapsensor linearisation wrong, or something, noone i know can find and change linearisation of mapsensor volts/airpressure) but it operates in other volt range (instead of 1,6V on ignition, its lower) and ECU puts default constant pressure readout at 1024hPa.

For now I know that when car runs ok, its capable of 26 psi of boost, and 260km/h topspeed,
The best soft is probably the one a friend dowloaded from internet in july, but I have to run it with properly connected Airflowmass meter, before turbo with proper intake, I would prefer to delete it from map, as long as there will be no big smoking because of lack of it.
But it should be possble to limit smoke based on mapsensor, and boost readout ?

any suggestions welcome.
The guy that was payed to write me a map, is not answering phone ... and I am to stupid to modify winold without any help or guadiance.

I was thinking of replacing elements to 7,5mm, and getting in this pump, but looks like i will have to change gearbox to manual, and put mechanical pump ? unless I find help.

There are 3 map sets in the above rar archive.
ver 1 , i do not chave.,

https://drive.google.com/file/d/0B4eNTM ... sp=sharing
there is:
1. stock map
2. ver 1. missing(i didt dowload it from chip (was 5500rpm max, 27psi boost, little smoke, good map, but after hitting 27 psi went to overboost error, and had to swith of engine for 10 seconds, + intake with MAF is complicated, so I asked to delete MAF. and increase a little bit fueling 2500-3000 rpm,
2. ver 2. from march 2016, MAF deleted, fueling like crazy in low RPM, big clouds of black smoke at any revs from 1000-3000 than air clears, undrivable. Ofcourse after hitting 25 psi goes to no boost at all.
3. I left the car at mechanic for 2 weeks. He came up with 3rd map, that most of the time doesnt work, sometimes kicks in during driving. told me to fool mapsensor with manual boost control, (after idea with 0-4 atm mapsensor from VW didnt work)
4. Map from internet , probably requires MAF , undrivable, but on my way on highway, used to kick in (MAF is installed low near bumper level to catch some air flow. I drove 180 km without overboost error, it was off everytime i slowed down, but power kicked in after cople of seconds of 100% throttle, very deleyed power response, probably because of MAF in bumper instead of intake.

this are my maps.

What type of rewritable chips you use for Mercedes 300td ? Will it run 28f020 eproms ?

Yes, it can run on 28F020 chips
I have 290TD daily sockets + 28F020

Posting in this threat to save it :D Soon start same road to tune my M-B.
