Quick question to every one who still follow this thread:

I had managed to upgrade the compressor wheel of the OEM turbo to GT2871R wheel (51.2 mm ind and 71 mm exd vs. 44.5 mm and 59.4 OEM wheel). I am also putting together intercooler for this project. Already have 4 bar MAP sensor and intake w/o flaps. Planned changes to the ECU map are:

Higher rail pressure.
Timing adjustment.
EGR delete.
Injection pulse width adjustment.
Changing turbo vanes open position - maybe using longer rod.

My question is:

W/o changing or overhauling my injectors what power gain should I expect.

Do you have a 6 inline or V6 320CDI ?

isstay

I6

Is the Map sensor ?
What rail pressure sender you use? how many bar?
Do you have part numbers

Thanks

isstay

What about the MAP sensor? I have two different ones that are 4 BAR, one is from Opel other from VW, but both are made by Bosch (I can look part numbers if you need them). Both read pressure and temperature. Fuel system stays same, ECU remap will raise the rail pressure up to maybe 27000 psi (1862 BAR) from the current 23500 (1620), sort of like those Performance boxes but through the pressure sensor by itself. Turbocharger is stock on the hot/turbine half and upgraded to GT2871R (51.2 mm ind/71.00 mm exd) on compressor side with new billet wheel (OEM wheel is from GT2859R with 49.5 mm /59.4 mm respectively) so it flows more air under higher pressure.Intercooler core is made by Bell Intercoolers.

Is the map sensor PNP?
So you want to use a fooler for the rail pressure sender?

isstay

Yes, only thing that needs are bigger holes for sensor by itself and the bolts plus 3 wire connectors, just have to make the original holes bigger, and introduce it in ECU map.

No, no fooler will be used, I said "like" because that what they do - alter the signal from fuel pressure sensor, thus raising fuel pressure, ECU map is getting changed so higher pressure is build and held in the fuel rail.
Beside the turbo and cooler everything else is done through the software.

OEM vs. AM.

diesel2fast4u

Do you have a part number?
Also for the rail pressure?

thanks alot

isstay

Bosch #0 281 006 060 refer to VW/AUDI #03K 906 051 available here:

http://www.darksidedevelopments.co.u...k-906-051.html

But I don't understand your question about the rail pressure, I won't be changing any fuel system hardware.

diesel2fast4u

On the fuel pressure sender that I have is indicated 0 to 1600 bar, after 1600 bar he's at full reading so if I have to change him for a 2000 bar or more

isstay

Now I understand what you where asking me, sorry. My assumption is that I will have to replace it.

diesel2fast4u

I have been playing around with mine for a long time now.I think that
if you want more then 300HP without injection duration that will give you sky high EGT you need a different map & fuel pressure.
We didn't find the fuel pressure map in the ecu though

isstay

But you have V6 w/DPF and so on emission junk (ECU map is different and more complicated). Mine is I6 and has only cat and O2 sensor before the cat. 2.5 inch piping to the end of the car with only two mufflers. The guy who will tune the map told me that he will change timing, rail pressure, injection duration (pulse width) and turbo pressure setup, so I will assume that he knows where to find all those settings in the map (I assume and hope so).

isstay

Here is info for all Bosch fuel pressure sensors and the rating they have. You may have to fabricate adapter if the OEM and after market ones have different threads.

great link ! thanks

hii... Im pretty much new to tuning diesels so far.

I have a 05 e320 CDI, with just a eurocharged tune on my car, and have a muffler delete. I wanted to know how to get more performance, i have read this whole thread, but i was just looking for somewhere to start.

The tune put me at 212 WHP and 370 Tq at the wheels.
This was ECU flash.

What else can i do to make my car faster. !

hi, i need your help guys, i need a bigger map sensor, i heard that the diesel has a 3 bars map sensor, can someone confirm and part nb please.
thanks. and who tuned the ecu for bigger map sensor?

isstay

Bosch #0 281 006 060 (from AUDI, VW) and #0 281 006 052 (OPEL, VAUXHALL) - 4 bar (3 bar absolute) - those have temperature sensor build in, but you do not have to use it.

3 bar (2 bar absolute) MB # A 006 153 99 28 or A 004 153 31 28

4 bar (3 bar absolute) MB # A 007 153 00 28

thanks so much
the 3 bar(2 abso) i found today playing with EPC are:
006 153 99 28, 006 153 15 28 and 004 153 84 28
i think the 004 153 31 28 is 2.5 bar not 3.

isstay

this is currently on my car and i doubt that is 2.5 but anyway.

isstay

This is generic tune, anything else you want will require parts - bigger turbo, custom intercooler, few sensors, more fuel and custom tune.

Guys i need help, i just installed the 006 153 99 28 on my car 3 bar instead the stock 2.5 bar, it did not work! the car did not idle.
is there anyone here on the forum went with bigger map? who tune for it?
who calibrate the ecu??
thanks.

isstay

Whoever tuned your car after you put bigger SC should be able to do it for you.
They all max out at 4.5 V - just different number 3 instead of 2 and so on. They should know were in the MAP is located and should be able to change it.

Hello all,

I have decided to upgrade my c220 using the good advice from this thread.
I have a question for Tuikku or anybody who knows the answer.
In terms of the turbocharger, I have understood that the GT2359v is the best option, and that the one with the vacuum is the best due to the position of the pressurised air outlet.
I have three part numbers for this turbo:
6130960199, 6130960299, 6130960499
Anybody knows the difference between them and which one to chose?
Otherwise has anybody succesfully installed the one with electronic actuator, part number 6480960099?
Tuikku, you say that you have the vacuum type turbo with an electronic actuator. Did you just fit an electronic actuator?
Finally, how did you guys fix the turbo? I don't think it would be wise to have the whole weight of it hanging off the exhaust manifold. Did you create custom fixtures?
Thank all,

Michel
