Hi guys and the few that use titanium and are inexperienced, I bought a alfa 19multijet 150 hp
And I discovered that it was already mapped and evil besides
Practically had lifted the values of the turbo without
Touch the limiters have increased 150 points
And the machine mi fails when it sank l throttle
Then I got up to 150 points for the limiter, but fails the same less but the same
What should I do??
Thanks to all
Alex
prepare a map ori the write try the machine and see if in the meantime it's fine . you have to go by logic, not by trial hello
With the gold goes well with my doubt and when I lift up the parameters of the turbo-150 points how much points I have to raise the limiter??
But before seeing the map or not map, because you have not made a diagnosis to see if the breakdown of that is on the turbo pressure? could it be another thing? with the map ori should not be in recovery because he has a request that is different from the modified map, it is normal, but should be fine with the change if the stain is applied.
It is, in fact, I have done the diagnosis and I know turbo pressure low
Place that, as he says rightly egs, it should be made a diagnosis in order to understand if the problem is that the failure is the pressure of the turbo, it would also be helpful to understand which version of the 1.9 jtd have. It is a 147 €3 with ecu is EDC16c8 or €4 with EDC16C39?
Given also that I am a user principiantissimo I advise you to take everything with pliers, what I will say and maybe wait for a confirmation or a denial from some experienced user.
In the case of edc16c8, the original map of the 150 Hp seems to me to have to 4000 rpm and for 70mm3 of fuel pressure, turbo 2330 which is also the expected maximum value in the map turbo, then in the version of the mod if it is increased to 150 points, the pressure should be 2480.
The maps of the turbo should be 3 addresses 0F82DA,0F851E,0F8762 and are all 3 identical, then there is a map to the address 0F89E8 which is full of 2400 which I think is a restrictor in the turbo pressure as a function of the external atmospheric pressure and I believe that if this was not adequate, obviously, as they exceeded the 2400 would give an average and I think there's another bit that is located just after the map to the turbo that limits the pressure and also this should be changed to a value that is obviously superior to the 2480.
Then the machine and euro 4
And error and p0237 pression low
pression low= low pressure...Originally Written by alfa150cv
Are inexperienced I use titanium I have increased the turbo pressure of 150 points and also the voice limiter turbo I have increased 150 my doubt and it is not that the machine when the pressure peaks should be even more on the pressure and maybe I have to raise more the limiter? ?
Because if not fo rapid decompression should not be in recovery
According to me, it is possible that there is a peak of pressure that goes beyond the limit, and probably raising more the limiter, the problem disappears, but I seguirei in a different way, or will a little bit the management of the variable geometry making it open just a bit more to do to reach peaks so high pressure.
I repeat, however, take everything with pliers, because they are not very expert, wait for advice from those who know more.
I I were you I'd post your modified map and the ori, here there are so many users that are experts and would give us a eye on it and advise you for the best
