The map Difficult to Bmw 320Cd 122_369

[bmw320cd]

hi to all

today I read with galletto v54 the serial file .ori of my bmw 320cd 150hp edc16c31

and I went into total confusion regarding some of the torque limiters torque limiters

the whole way I did the first change, of course, the map is incomplete and is not writable,because it lacks almost everything....pero useless to go forward if I don't do well with torque limiters

so here is the limiters that I found but I do not understand the operation....

torque limiter #3 map (1/3) --> 0E8262 to 0E828A

torque limiter #3 (map 2/3) --> 0E830E to 0E8336

torque limiter #3 (map 3/3) --> 0E838E to 0E83B6

then I think I have found the torque limiters for each gear,here are the addresses

--> 0FD0BE to 0FD0FA


I don't understand fully the operation....because at a certain point down to 0,then to ascend and then descend again definitely.... just out of the way here are

while in the other limiters



from 0E7CA6 to 0E7CCE I run the "classical" straight line (torque limiter #2)
from 0E09B8 to 0E09E8 ditto here as well... classic line,increasing towards the end (torque limiter #1)



then the driver wish already adequate,they obviously do always try it,given that they are still at the beginning

idem rail pressure and relative limiter

limiter pressure turbo the increased advance,because then will work on the turbo pressure....

someone explain to me?

anyone? they are really on the ball with these limiters.... needless to go next on the map (which I can do) if I can't superere this difficulty in this file....

[bmw320cd]

I don't know why once you have sent the message can not be more change to add new attachments
anyway, here is how I have operated with the limiters indicated in the addresses of the message above...
I hope they go well or they are all wrong?

watch sincerely with regard to rail pressure and rail pressure limiter can go, but for the restto map enrichment accelerator too soon with the change, and the increase did not see it proper,you have increased the limiter pressure turbo (incorrectly), but not the turbo pressure and the various limiters you are incremented are made with a logic that is wrong also, the speed limit doesn't have much meaning,I would say first do some research in the forum with discussions on maps similar, and focus only on the main map, and then to deepen the rest,with the maps in the main, you can easily pull out 30cv without a lot of effort and without complicate your life.

ok then, rail pressure, there are...

1) the map driver wish I leave early,because the 320 has a sensitivity of the pedal-meta practically nothing....to do this move with the decision you have to always go beyond the 60-70%, for this I was given, even at low loads, a request to the higher.... however, I've moved the increase more forward following your advice, and why not show adequate?

2) on the limiter pressure turbo, I think I understand the error,and in this new map should be ok... I also touched the turbo pressure with a maximum of 150 points,as written several times here on the forum,without increasing too much...

3) on the torque limiters unfortunately, as I have already said, on this damn file,I can understand how it works,so I pulled a straight line.... if I may how to work those addresses from me posted,it would be better....

4) speed limit redone as well, we see in this version if all goes well...

5), as well as the injection time... injection (split)

[msport (exil77grande)]

the injection split the increases start with a % acceptable but end up overly,while on enrichment and acceleration that's too soon to give and risks of smoke and putting too much stress on the flywheel and clutch and also start them off with a % acceptable but end up overly,torque limiters incremetali starting from the same rpm that you will take as a base a little bit on all of the maps and perhaps by no more than about 15%,the speed limit can also leave you so but you have not figured out how to do it but it doesn't matter it's okay,the timing of an overboost forgive her ori,turbo pressure can go up even if the similar maps are slightly unpacked, but also in this case, leave them so they can go,the pressure limiter turbo adegualo pressure turbo though so you may leave it if you want,the more of this I can do and then do it all and try and draw your own conclusions from that,good continuation.

step4 of my file... I adjusted what I have told you,except for the torque limiters... I found a file of the 320cd and I saw that in the torque limiters pull straight lines to a certain value....then I'll try and I'll know....in the case of limiters incorrect, it should go into recovery right?

I also increased the rail pressure at 5000 rpm, bringing it to the value .the gold of that wax 4400rpm (should be 1600bar, then rail pressure practically ori,but instead of 4400rpm at 5000rpm...I think this should give you a little more power especially at the top), so do not be scared if you find +146%, because the decimal value ? equal to that of the ori 4400rpm....

dropped some point the pressure turbo, I want to see first how it goes with these injection time, and in the case then modify it accordingly....
ah one last thing,let's say a fundamental... the damn egr I saw that ? the injection phase,but being edc16 this does not close as in the edc15 bringing the decimal to the maximum.... I had read that they had to find "cakes" or something like that...could you give me a hand for the egr?
I'm learning a lot I hope....

Hello
Some torque limiters show the inner torque'an others show external torque.
For the EGR you need to find 2 hysteresis map, after the EGR map.

thanks but I can not understand the differences between external and internal torque limiter.... what does that mean and how they work
I'm working for the egr

[biela]

The Inner torque is related to mg of fuel injected.
External torque or output torque is the inner torque minus friction losses.

[bmw320cd]

The Inner torque is related to mg of fuel injected.
External torque or output torque is the inner torque minus friction losses.

in this file, which is the internal one and the external one?

[biela]

The Output torque has got lower values.
