Hi
could someone explain to me how can you understand when a map ? on the contrary. I knew of the marelli, but I have a file of a bmw and I have the impression that they are on the contrary

Hi
could someone explain to me how can you understand when a map ? on the contrary. I knew of the marelli, but I have a file of a bmw and I have the impression that they are on the contrary
however, someone more? expert and that you know how to explain better arrives !!!!
We take into consideration the torque limiter, immediately after the BP does not have the torque value corresponding to 0 rpm, but the max rpm. Pu? be
Why? I ? appeared the message "? important to read the rules" ?Quote:

hahah it is a writing that appears in each of the last message of the various posts,in this case the last to write here was you, but now after my reply you will see that buying on my message.Quote:

I had not read the other messages belonging to the regulation, that's why? I had not realized. Thank you and sorry.
P. s. with regard to the topic of the post, no one can? suggestions?

To understand the true meaning of the maps, their orientation, and the conversion factors you need damos specific.
If you have not, in most cases, just take into consideration the map for a time and test with a good diagnosis
also the marelli they are not,they are just based on the bp.....
Excuse me an example
On 6F3 you can take as an example the rail pressure.
look at the torque limiter of this map (the map ? ori, if you need it for the archives of the forum you can also move it)
here is a screen so you should see it.

and here's what the grid.

I have said that ? on the contrary, so I'm not sure, I ask you to confirm.
the first part ? the bp and revolutions,the second part I see normal,estimated that the 1.4 mjtd after 3500 rpm die then ? the normal curve that falls cos?...

I thought it was a marelli,sorry but that unit is to mount the x3?
that ecu ?? edc16c31 or c35? ? the first time I hear of maps on the contrary on bosch then..according to me ? a normal torque curve anyway the hand on fire, do not fix it and I would wait for other confirmations
sorry but I maps I read them all from left to right...
Where you understand that ? 21x1, and then torque limiter in the lap function?
from the bp before the torque curve,before the bp usually c'? a number or 2
if there are two 16, for example, the map ? 16x16
21x1 means that the map ? composed of 21 points and has only 1 axis of his reference.Quote:

ok thanks for the clarification.
I had had a doubt why? if you notice at low rpm, type 1000 1250 1500, do you have torque values high, while at higher engine speeds are more? low. Then someone told me that it was on the contrary
among other things, a limiter do not want to say that necessarily the engine to get to those values. I note also that the "couple" that you see on a edc16 ? an ideal value, then 500Nm provided by the control unit are unlikely to 500Nm at the counter.
Absolutely right, ? a "limiter" and therefore not an objective map.
We must think about the conversion tables, as did intedere SandroMarciano, to understand the meaning deglio NM required and limited
I would say most holy words,then everything depends on the logic of the single map and a single logic of the engine control unit
There are different protections to adapt to what you want to achieve and not only the torque lim "classics".
but what? the bp...sorry....Quote:

break point.
if so, we can say of the curves before each map management,who say to the map management how to work and on what basis,as the time of injection on the bosch on rail system, the break points are based on the rail pressure and the engine rpmQuote:

or even rail and quantity? diesel,is dependent on the cases
so if I understood well...knowing the bp can't determine when increments of make....right!!
The only way to "logical" to modify an ecu is obtained by knowing all the real information you need for...***** and bp, the conversion factors and the meaning of each map that is going to touch you.
But in the marelli, the maps on the contrary, what are they?
