There guarder? better tomorrow, what time are time...
But in substance, that limit and what is the meaning of these maps?

Request rail pressure at cranking
PrailRef warm-up weight map
PrailRef warm-up factor map?

Are 3 maps that in fact I was not touched... why? I didn't understand and I still do not understand their operation.
By placing these you have solved the problem of the pressure jump?

Increasing these maps, and the bit corresponding to the cut diagnostic described before, which is to be modified in the same way that you change the bit limitation, I solved the tripping of the pressure..

[Fede78]

The bit 6748E led to 850, and then (850x2 - 100 =1600 bar)
C'? this is the only bit of the right cut?

Now I have to try to understand these other 3 maps (pover? to take a cue from those of the MJD8...)


I know that it will have? increase the counter of the scriptures on my point.. I know that are already? plus 100 scriptures
Found this solution and then seek one of the lim of the turbo
Then... from the damos of the MJD8 I extrapolated a map that may limit the quantity? maximum fuel... in fact in the log, I have never gone over to the 42 mm3), although only peak...
Can be 065574 (map 4x1) eprom*0,002930

However, one thing at a time

I also noted I that the map you indicated 065574 also present in the 75hp, regarding the turbo pressure and I'm working on not ? just a bit limiting, for the pressure gas, please review the previous discussions and you'll understand what to change

I tried to pick up 50 points all over the map 0677DE and a 15% across the map 067966 but no differences...
Now it remains for me 067886 but without coming up with some ideas... I don't get it right.. 16-bit +/- I have negative values... or without the +/- values are very high and even with the factor of 1.6 x eprom as you indicated, I will not get out...

please carefully read well

the maps above taken from the file lancia Y annex at the beginning of the forum, in addition, look for the bit 01d4 0307
change the bit 0307 in the same way as the bit restriction rail pressure

Guys, if you have the patience, late in the evening, place a screen of those 4 maps, so? think it through better

06748e bit that is located at 775 (multiply x2 )limits to 1,400 bar (offset -100)

as you can see are 13-bit part 50 and arrives at 1600, likely, instead, that it starts from 067496 and should be limiter prail in function of the pressure of the turbo

This here we all know, ? the map rail pressure indicated by the ecm.

attention to the addresses posted by backgroop...it should be I THINK a lim rail ftemp but I don't understand the axles and I am not with the conversion factor

it is here, it seems like a limitation in the function of Iq, but I'm not sure...

067946 - 0679e4 Rail Press. Gov. - PrailRef warm-up factor of the map: f(pTcool, Patm)

I believe that being here is a real map of limitation, precisely, as a function of temperature and pressure atms.

Being here I know of limitation...but I don't know the conversion factors,...okay on the z, I read the prail (offset -100) but the axes...

[munro]

I believe that in the a-axis(Y) there is the temp diesel in degrees celsius....
in the other, I think something related to engine revolutions per minute+turbo pressure...

[Fede78]

please carefully read well

You are right, I would assume that you bit 0307 there was only one change, and I had escaped what 0605BA...

Tomorrow I try again and who knows what I can understand those last 3 maps of the rail
