Maybe me too...I don't know, because I haven't seen/touched the ignition table.

With the turbo table is all ok for you?

Maybe I found the solution

In "Edith Parameter XDF Info"
Rows
Address step: -2

Previously I had 2 as value, I had to put a minus forward and the table appears correct now

I've to test it on the street...

Gday mate.
Have you tried ecuconnections.com and ecuedit.com
Both forums are full of semi pro and pro mappers and have a rate my tune thread. I have found mapping my old Alfa Romeo fairly straightforward after a few hrs on these two forums.

Hi there,

I'm the guy that did the legacy XDF file long time ago. I set the 8000 offset in order to get the same address range the ecu code is using. It doesn't hurt as there is no map data before 8000. Sorry if this confused you. Be careful if you change the offset value : I don't remember if the checksum calculation (header section as well) does depend of this offset value or not.

Happy to read the definition was enhanced. I consider buying a 16V turbo again in few months. I'm missing this car.

UP!

Hi! After two years I'm back mapping with Ostrich and Tunerpro on P8 IAW. I made my own xdf and now it seems 100% working. I found other errors on JMA xdf. I don't remember all of them, but the most important is that in the duty cycle table, the colums Address Step has to be negative, while it was set positive (2 but it has to be -2).

I would ask you a thing, if you know it. I'm working on a friend car, so I don't have it with me and I can't do the things I want when I want. Anyhow, we set turbo boost max to 1.5 (Lancia Delta Integrale Evo I turbocharger, so a bigger one) and the car goes very fast. But the friend of mine would put the overboost to 1.7 bars (he is a very good mechanic and the engine very reinforced, he knows what he does with cars, he had an Integrale with 2 bars boost, only he don't manage computers, so I then go into the game). I ask you: is it possible, removing the turbo limit (I see the limit is 1.55 bars with 255 converted with the formula) to go over 1.55 bars, or the car will cut (due to aps limit or a P8 limit)?
Any of you has a map with more than 1.55 bar on his car (obviusly with the Iaw on it)? Thank you very much!

Is it possible, i think. But i never did it lately on all iaw ecu. Installing and remap for larger reading map sensor is not huge work and you still have failsafe boostcut and proper fueling(ecu still adding fuel, even you dont have maximized kpa axis in fuel map, for example).

Hi, thank you, yes as you says, I find out it's necessary to mount a 3 (2) bar map sensor and then remap. The friend of mine mounted the sensor and says the car runs good as with the 2.5 (1.5) bar sensor. Only I don't know if it's necessary to do other things more than put all the turbo limit curve to 255 to rise the turbo pressure without cuts.
About fuel I'm not worried. At the moment, at 1.5 bar the afr is 10% so very rich...this thing for safety...

Hi. You need to adjust all the fuel and ignition maps to suit the 3 bar sensor. You also need to recalculate your boost limits to suit, because of course they will all be out by 20%.

Hi, as I said, the turbo limit is not necessary at the end if you know what you do. So I put all the turbo limit to the max 255 value...yesterday the friend of mine tried the eprom I made for him on street with the 1.5 map sensor... but now mounting a 3 bar map sensor. He says it's good. He says that the fuel ratio (I haven't touched it for the 3 bar map sensor) is good at all range. The turbo pressure has a peak at 1.6 bar (with 4th-5th gear) witout cuts and 1.2-1.3 of constant pressure.
So it seems it's not necessary to do other things indeed...he says the car is very powerful :-)

Just to precise things, you can go above the max pressure reading of your map with stock ecu by putting 255 on max values for boost pressure limit.

It will keep the last known values for injection and ignition data.

You should also think about timing as changing MAP without rescaling the hole thing will read lower pressure timing values (which are usually higher) and this could also damage the engine even with rich AFR.

Also You must know that overfueling is not good for an engine as underfueling.

If you are ready to send your xdf we could share our work, as I have also worked on it.

As I said I'm not a beginner and I knew that thing for IAW 4W-4WE of Delta Integrale, ecus on which I was used to work on. So now I exerimented that it's the same for P8.

I haven't controlled, but the friend of mine says that there is not knocking. There is a knocking device mounted.

I found 11% of afr at max boost on standard integrale's maps at 1 turbo bar. So it depends which is the value you mean as overfueling. The only things that can happend are cleaning oil from cylinders and fuel in oil. But I think you have to put a lot of fuel more. The friend of mine (I repeat: he's an expert mechanic) says that if we have that ratio at high rpms and turbo pressure, it's a little bit lower as %, but the engine eats all. No black fog or exhaust detonations...just to say two things that could express too rich carburation

I didn't want to tell you that! I don't like it when people disable boost safety cuts laugh
