I'm about to tune my car, tdi 1,9 PD engine.
I have made som changes with great powergain but now I see a limitation in the duration maps.

Why is there six maps? What do what and do I have to change them all?

Duration maps are related to SOI maps.

SOI maps are related to coolant temperature and fuel temperature. Combination of all of those maps + IQ that needs to be injected gives which SOI map will be used.

Different SOI gives different Duration map.

Depending on the tune, sometimes there is no need to change the duration maps, but sometimes they need to be changed.

I work with my file in VAGECU15P+Suite, when I opened it alot off maps just showed up, no search for maps at all.
I have 6 (12 with duplicates) duration maps but only 1 SOI map named 0ºC.

Almost all my duration maps peak 65mg/stroke in axis, and below 55mg/stroke has same value, witch means I will never get more fuel then 55mg/stroke, am I right?

To specify more I have ATJ engine, 115hp. Map addresses are not the same as PD130 engine have I discovered.

I need more help go understand the situation.

All PD engines have 10 SOI maps + the duplicates.

I do not understand what do you mean with this -

Because there are so many PD sw - when you ask for help it will be nice to post you ORI file and post the maps address that you are talking about.

Thank you for your answers!

I now understand there is more SOI maps. I find more SOI maps in Winols with some help from youtube vids.
But they are not namned in VAGsuite, does anybody know how you rename them?! I probably can get all maps needed with Winols but I need to get them namned and categorized in VAGsuite :/

I meant duration values makes curve not rise above 55mg/stroke, you understand what I mean when you see the map yourself.
I upload both originalbin and my latest modified

Addresses of fuel maps automatically recognized as folow (I skipped duplicates):
Inj dur 0 6146A
Inj dur 1 06157E
Inj dur 2 61804
Inj dur 3 61A8A
Inj dur 4 61D10
Inj dur 5 61F78
SOI 0°C 060F94

- I must correct myself. This is the first PD engine file that i have seen with only one SOI map. :oops:

For what market(country) was this car made? What year of production is the car?

About your tune - This is the worst ever made file that i have seen. Looks like you hate your car so much that you are trying to blow your engine. Lucky for it there are few limiters that still hold you back.

The car is made june 2000 and was sold here in Sweden. The 115hp version seams to be odd, not often you read about in ecu forums etc. I think it's the first VAG PD engine ever?!

I'm glad you liked my setup ;) Because you have so strong opinion about my tune you maybe have some advice?
What is so terrible? I'm totally new to ecu tuning, I do have some basic knowledge about diesel engines due.
I drive with that setup today and it works fine beside I get a low boost failure when I push it max. I think my worn out turbo can't handle my boost request :)

By the way, I found a duration selector map in Winols, address 621F6. Witch data is used to determine map selected? What factor/offset should I use for X-axis?

I appreciate your help, hope you can continue make things clear for me!

Incorrect.

Something is wrong with your turbo setup (boost, N75, PID).

Is that so?
Actually, the map I upload is not exactly like the one I have in my car now. The N75 and EGR map is not modified in my car yet, as they are in the file you read. By the way, my turbo is worn out, I inspected it when I had it out to clean turbine mecanism.
With the N75 map set to 80% maximum as original the boost went to max 1,7 bar, maybe thats in order?

I didn't check the maps.

If you didn't alter a SVBL, then this is a reason turbo boost is limited.

If you didn't alter N75 map, then this could be another reason boost doesn't reach requested (modified) boost.

beside, 1.7 bar is more than enough for a fast road and track remap that is done right. I am currently running 1,45 bar and have more than enough torque.
