Tips map Ducato 2.8 JTD 127CV

[zluca71]

Hello all, can you give me some advice on this map that I would like to try on a Camper van Ducato 2.8 JTD 127CV. The goal ? get a bit of torque in the pi? at low speeds in order to better cope with the climbs, considered that the vehicle is traveling almost always at full load!

Hello Luke, I'm sorry for not being able to ranks of pi? x, which I can't read the attachments, I have a Iveco Daily, and I have given at low rpm a lot less on average smoked a bit, but he had a breath in the boot

that you can't help him know that, having regard to regulation, however, even if you can't download, you can give him the guidance he needs, then you do not need to download.

Hello zluca71, to get help, you should upload the original as well, given that you did not put even the data of the ECU... ;)

[jolidj]

in fact, without the original tt is more difficult .

[zluca71]

Sorry, here is the original file, the data of the ECU HW: 0281010931, SW: 1037366765.

hi, you can take a cue from this discussion, in which you analyze an engine like yours, even if you may not see the attachments from the speeches we understand, however, very much.

Sorry, here is the original file, the data of the ECU HW: 0281010931, SW: 1037366765.

I will have you know that we file ori posting in the section database file ori if not already present, and then you paste only the corresponding link in the discussion in question.

[zluca71]

Thanks for the information, I'll have to remember? for the next post..

[zluca71]

Thanks SandroMarciano, the discussion that I have reported I have already? read and I followed part of your directions for the map that I posted, I would like some advice on this map, and figure out if I can upload it without problems.



Thanks

What are the two values that you have changed addresses: 7BD7C and 7BD7E?

[munro]

hello I gave a quick look to the sun maps moddate in the driver and I have to say that there are things that I think are not good...
for example, the map pedal does not touch then your demand for diesel fuel, and stops at 74 mm3 but then for? in the lim couple decides 78mm3...and in the lim fumes you are always limited to the value of iq ori... why???
the mappache ecm calls injection phase and related to the hysteresis egr if you want to quit you have to bring all the values in the table to the high value that you see in the map...***** and the made you do not need has nothing..sae did not make you turn on a malfunction indicator light...
you touched on, even if just a little map press the rail, but then do not adapt in the same way his limiter I wonder..why??
in the maps the map x boost 1 and 2 that are referred to you times inj in the first map,the map x boost 1,which are the times from 0 to 2500 rpm, according to me, that's too soon to moddare even if the increase and modest....
in the second map x boost could go..but have you made calculations as to inject with those times????
why? you haven't touched the maps turbo???

Hello,
I don't know what these values are, I'm working with ECM Titanium, when you make any change to any of the maps are also updated these value.. ? perhaps the checksum?

Thanks munro,
here is a new version taking into account your suggestions.
I have not touched the turbo why? this engine has variable turbine geometry to the electronic control, but a fixed geometry turbine and pneumatic control, I don't know what benefits it can? bring the change of the map.
I brought the map of the egr to the ori, I took inspiration for the increments on this map in a mod done by a professional, always up for a duchy, but in power (146CV).

now I've seen the map, but it seems not to have read the other thread... where I said that there was no need to change the rail and injection times. this means you can give diesel, by simply lifting torque limiter and pedal up to 100mm^3/i, obviously, then it is likely to be impacted also the other organs, and then proceed gradually.

[zluca71]

Thanks for the tips, I have been reading other post on the jtd engines and a bit of documentation.
Attached the new version, can someone tell me the pu? say if on this engine with turbo (fixed geometry not cotrollata from the ECU it makes sense to edit the maps turbo.

Thanks SandroMarciano,
attached a version of the "hope" as you suggested in the other discussion, I touched only the driver's wish and torque limiter with modest increases in the percentage.

[SandroMarciano]

I don't understand the need? to change the timing of fuel injection when you can give diesel in a very pi? simple and probably saving you a little bit of smoke, and then through the torque limiter and the pedal. the rest can? go.

ok, I replied to the previous message, this is the look, but I advise you to act in a finite value, you have to know yourself where you want more? and how much, consider that it is on the pedal and on the torque limiter will act by increasing the flow rate of fuel to be injected, without too many complications its maximum ? 100mm^3/s, but to have a means of performing non c'? need to get there.

in the morning, as promised, I looked at the map, the last post to upload it without problems ? a little light, but ? better if you go for degrees!

Thanks 1000, tomorrow I try and let you know.

I tried the map between yesterday and today, with a log before and after to write it on the same path, I think that already? very good, restored from just above 50Kmh in 5? (the first under the 70 was a lot of effort ? a camper that weighs from only ir? 30-Cwt), such as diesel now at the maximum injection 77mg/cons of 67 the highest. Now I just have to see how it behaves with the consumption, even if you touch only arrich. acceleration and lim. the couple should change something only when you "pushes"!!
