as you act on a map in the case of the intercooler?

[magi1984]

I have a curiosity? to ask, on a bmw 120d edc17 gi? mapped and sfappata and with the egr closed, the customer would like to change the intercooler, and put an oversized one.
I have to intervene on the map, or not ? need being gi? been mapped with an increase of the turbo pressure of about 150-200 points???

[legendaryslave]

see the evolution of pressure before and after the diagnosis, and will adjust accordingly, according to the theory, there is a decrease due to the increased surface area of the radiant mass to cross, but an increase of oxygen due to low temperatures

[SandroMarciano]

as a rule, an intercooler cools down the temperature of the incoming air more, so it increases the density? in parit? pressure. If you do not increase the diesel, we say that the replacement of the intercooler to serve? little.

[magi1984]

ok, I just need to know how to intervene, and gi? saying increase in the diesel fuel, I put you on the right road, great!
there are many ways to increase the diesel fuel, injection timing, amount? fuel injected, rail, etc, etc, there will be? have fun

of course, if you have any tips are welcome

Depends on how you performed the change, or, if you simply increased the stroke, without adjusting the axis of q.the. then you will need to make increasing the time until the attainment of the smoke, and then go back (to trial), but if you have unlocked the torque limiters and q.the. then will we need? set the lambda to a value greater than 1100punti if you do not want to smoke and increase the torque. If the limiters were properly adjusted with this system decides everything the ecu, then just a single attempt....

moddando times it bites better...and if you put a ic plus I bet that the guy wants to senire feather...

[munro]

in practice, an ic plus good workmanship can cool down more, the compressed air that passes through it, even with the same operating pressures turbine for a speech efficiencies...
and as I have said this to cost reductions of temperatures makes it the most "thick" the air intended for the engine and then with more oxygen...
generally then you can give more diesel because c'? more air and more pressure turbo because c'? more disposal of heat of the same, that does not affect in a significant way, not even the operating temperatures of the engine...
if you want to make an ad hoc work according to me you should be saying to the efficiency of the new ic, and through this calcolarti theoretically, the quantity of air at the exit of the ic in order to compensate, so stechoimetrico with diesel....
otherwise you risk going to trial and error before getting the right "mix" of air and diesel....

the intercooler ? the kit performance BMW
so theoretically I would only need to find a map of the kit performance BMW and studiarmela

[giuseppe1374]

I'm at the point if he wants to put the intercooler would also recommend the replacement of the injectors

[bart]

According to me, lowering the temperature of the air fed into the combustion chamber, you might consider to work on the advances of the injection and/or the pilot injection...
