Map Alfa 147 1.9 JTDm 120 hp

[SandroMarciano]

the gt2256 ? a turbine is bad for our processing, the horsemanship I, and are not at all happy... according to the compressor map you can keep max 3bar absolute at 2800rpm, then go down to 2.65*4000... no ? the maximum, even why? ? very clumsy, in starting to push. I would say that anyway ? enough to squeeze the can from the plant iniezioine of the series.

Then, if you are talking about va and VB already? you don't know these engines, since? va and VB are fitted on the injector pump of the vag group and on some of the rotary pump of the same group, the 115 and 120 hp montano, respectively, gt1749v and gt1749mv that differs from the first geometry was improved "multivane" as to the gt2256v that use ? of the same generation of gt1749vm and has the same strength, it varies from model to 175cv multijet only on the nut of the exhaust connection at the exhaust round instead of triangular, with screws but the core assy and the same. The same Barrett for their compressor 56mm bushings on a compressor map that exceeds 2.0 bar of boost, more than 25 lb/m intake, then pu? hold the 1.8/1.9 bar without problems if you do not claim the 5000 rpm, where the heat generated by the egt is likely to cause harm, in fact many make it out to that number of laps.
The turbine ? mounted on the necks of the original but changed the attack to not suffer deformations and seal trimetallica.
I'll give you reason on the fact that we have been able to mount a turbine as the gtb1756vk that but he had also recommended Munro or a gtb2056 derivation Brera 210cv, but I had to deal with my pockets and I opted for a choice that guarantees me anyway, a good cavalry in the order of 190/200 hp, of course I know I could not expect more than but enough for me and I advances given that the car ? for normal use, and must also and above all last longer than that give me some satisfaction every so often where it is allowed.

Hello tidus saw that it seems to me you know very well the 1.9 jtdm 120cv I wanted to know, according to you, the maximum operating pressure for the turbine of the series as to the various forums you read of all the colors, etc., Attualmenta my travels at around 1.5-1.6 bar peak. The map turbo in the ecm indicates a maximum value of 2500 that are prex absolute no? the compressor f? 1.5. How to increase we are on the 150pti with respect to the base map.

Maybe I did not express it in the right way, speaking of acronyms mounted if different cars, it does not seem appropriate to say that I don't know these engines..
Va or vb are only 2 versions of the pi? recent v 1? generation 1.9 jtd-m 16v 140cv, then they are mounted on audi or ww what to change? the core assy are the same.
Many mountain 2260vk that ? derived from the bmw, the other 2056vl derived from the volvo, the other 2260vklr of the mercedes, just redo the manifolds and some adaptation.
The core axis between ww and alpha are the same on the v of the second generation alpha and va and vb ww.
If, instead, you speak of the vm if you want to mount it you have to cut off the nut collectors, why? ? a single piece.
If you have made this choice for economic reasons, then that's okay. By that machine comes your 2256?
Then pi? that the pressure in the test phase, you should keep under control the rpm of the turbine.
If you spin with about 190/200 hp you should have a good standard

I apologize Blackhawk , I didn't want to offend you absolutely, we are all friends here the starno ? as you say I too until recently I knew of the vm as the theme of the nut of the exhaust and the hills in unn single fusion, but my turbine from the database garret is referred to as gt1749vm, and turmax told me that differed from the first in that the variable geometry improved, hence the name mv "multivane"
if, then, the explanation is appropriate or not I don't know that for sure.
however, my car takes up 190/200 and maybe 200 I don't even know if it gets there, an injection-110mm3 of diesel and I have pressure in the order of 1.6/1.7 bar of peak-to-2000/2200 rpm, 18/1.8 bar peak 2700/3000 laps and then falling back to 1.7 bar over 4000 rpm and, for now, no sign of the surge and the game on the impeller controlled even today.
now I'm trying to accaparrarmi a gtb2056v derivation 2.4 210 hp to put in the hills that I have and keep it for a possible greeting of the current turbine, although I hope not given the care that I have in it to heat up, in the off and in the treatment of teflon on the oil that I run with every oil change

with regard to the va evb I read in the forums wolksvagen of people that the port with no problems at 1.7/1.8 bar, so I suppose I have something different, because responding to thekid, I for 30000km I have never had porblemi with the turbine original, a fixed pressure of 1.6 bar after 2000 rpm, and with piccate 2 bars when I had broken the pierburg, sold without the least game, so held good for the buyer I think it was rebuilt and not used, while sandro. cracked to 1.5 bar, so that I say to you, I would say that in my experience is not the make out, as long as you use good oil, coupons also 15000km ( I do them every 12000 km ) and in accordance with the cooldown and pulling only oil above 70 degrees, for the rest I would tell you even if you do not ? "technical" who goes to a fortune

Hello to all, first of all thank you why? this discussion is helping me a lot in trying to change the map of my car. I wanted to ask you, I think I have found the 4 limiters iq in my map, 2 are straight lines with a value of 10000, the other two start from 7700 to climb. I imagine that those 10000 to indicate an iq of 100, then if I don't want to exceed this value, I can leave the original or am I wrong? Instead, the 2 with the limits 7700 no I can interpret them. Help?

[tidus1985]

the 2 limits to 7700 are limiters of diesel impoatstai to 77mm3, you can increase them if you want to make a map informed, looks good, the first one ? as a function of the fuel pump, for a number of laps, the second as a function of the temperature, I don't remember if water or other

Thanks tidus, so I wanted to get a iq of about 90 raise the limit to that value. I seem to have read that you just have to pull a straight line, without regard for the curve origianale.

If I understand the difference between informed and deceived ? in the first change the limiters iq and adapts the map times, in the second you change the values of the map iq\nm, and therefore the map times. In any case, for both you have to lower the values of the map of lambda inf and sup to prevent these limit the diesel.

I read in the discussion "edc16 impariamola" which, among the 2 kinds of maps there are differences, I don't understand the conclusions, but by informing the map ? better both in terms of consumption that yield?

PS Thanks for the time tables that you have inserted a few pages back, they are really useful. In fact, I have been following your inspiration to try to change mine. I climbed the values of the last column, based on the original values in the column 80, I've entered the new values that would correspond to 100 so that for inj higher than 80, the ecu has the correct values, am I right? You have found the technical data of the injectors in order to derive the time of opening\closing, you have been really good, congratulations.

The fact of pulling a straight line is not the best but still could go, the spreadsheet of the times and was created with the formula of the charge/discharge of the capacitor adapted to tinj, for the fact of the yield consumption depends, in general, the deceived should be better informed, it seems to go a little worse

I was wondering why? that informed it seems to me an approach to ir? fine, probably avr? the other advantages.

[jovandj]

Exact exactly as you say....with the deceived l ecu, and convinced that everything is going according to plan then not give a damn (less) of what happens to you while with the informed account of the whole earth
