MARELLI MJET impariamola!

[bob125]

6748E prailrefmaximum limitation value eeprom*2 -100
674BE lim rail f (boost) eeprom * 7.51
67946 I don't know
675BE the rail pressure
67A06 lim rail (temp, fuel) I have changed the whole map
677BE I don't know.. and I have not touched


then I would say
605BA rail max pressure
655D4 line HPUb1 - Rail pressure upper bound
655D8 line HPUb2 - Rail pressure upper bound


But you see that I run away a few bits in the map of michell is changed.
Also having my point 1065P351 I took this as a base and made some changes without having time to figure out which bits were
Let's say that the way it is, that file works to 1400 bar, changing 67A06 and 674BE instead, he goes to 1600 bar without any errors
Then I don't know if also serves as the regulator of pressure of 90 hp or if the functions of the 70 hp. I have the 90hp together with the flute (it is a change with a t for a return of the diesel)

Humm...I can't even download..
sorry, but the limiter rail, after the rail, what they call a ladder did you modify it? to 677de

[bob125]

the 674be the you've raised it all? the toes high-are at 199..you brought type 214?

[bob125]

sorry, but then if on a road 85cv (cos? they say....) I have golds in the table the value max to 192 means 192x14,5=2784 - 1000 = 1784mbar......I'm not a p? too many?

Hi erre, those values are relative to the variable geometry vgt..192= 75%...and it's all closed

[bob125]

However, these maps lambda should be decremented right?
I have to say thanks michell, who taking a cue from this map posted I've made some changes and I was able to edit my map and turn to 1600 bar, which in my tests of a few years the pressure going up and down and cut..
From the file posted by michell, however, lacks the limiter of the rail function to the temperature of the diesel fuel.
I have the engine, 70 hp, flute and regulator of the 90 hp injectors, 95 hp and BV35 (for now works at 1.2 bar)
Saw that I now have a wastegate that manages the geometry if I put, however, a faucet I could up the pressure as you do about the kp35 original no? at least 1.5 bar should keep?

Faith, but the turbo of the 90 or 95, ( I don't know if they are the same) have the same attack of the 70's??
in my 70 the turbo has the game( post...the palette, touch the nut!!) and I have to change it...that I put??
The lambda, or afr, marelli, must be lowered...as we should understand it with the log!!;-)

Should be the same attack as the cylinder head is identical then identical with the manifold, you may need to change the hoses/drain the oil turbine and possibly weld the gas pipe and exhaust if you're not, I say this because on my 1.3 I have made a change of the genre but with a turbine that is derived from the engine giulietta 1.6

[Fede78]

The turbo 90 hp must be changing by mounting a wastegate that can handle the geometry, then there is a water pipe and the pipe of the back of the turbo. The manifold is not from the tap.
I want to put on the GTB1549 that if I'm not mistaken it mounts the 2.0 mjt... only that them there to bother to change the exhaust manifold... but I think it would have been a thing fierce!
There is to say that once you have done the work if the turbo 2.0 is great too... you could also put the turbo 1.6 mjt and should have the same flange

It exact have the same flange, the change is not so much ruthless ec to sacrifice a manifold taken at the belly-up and to pay to the flange of the turbo above, and modify the exhaust and decatalizzarlo as I did

But the change to the wastegate I would be able to do it myself..I must make it a specialist?
water hose??...the 70 does not have water...maybe the 90's??!!
pipe return turbo what is it?

I hope that we do not go outside the ot

I believe that faith is the aluminium tube of water that goes to connect the heat exchanger tube and a return would be the hose that is located under the turbo for the oil drain lubbrificazione in the engine cylinder block

[Fede78]

Yes, the water pipe I meant the one that goes to the heat exchanger, and as the oil return pipe from the turbo to the block.
Now that I remember I have also replaced the return pipe of the oil of the turbine.
