Hello friends!
I present to you my project.

The car is Mitsubishi Space Star, 2004 year, 1.9 liter F9Q1 engine (Renault diesel), manual transmission, 102 HP, ECU is EDC15C3.

Changes:
1. DW – increased by 7% from 50% pedal in all rpm range;
2. Smoke map – calculated to give AFR 17,3-17,5;
3. Torque limiter is set to 58,20 mm3 max at 3000 rpm and it is below figers in Smoke map;
4. Turbo maps untouched;
5. EGR is off by switch and DTC for it are disabled;
6. SOI where the EGR operated before switching off are increased by +1* from 5 mm^3 to 18 mm^3 where is the EGR map dip;
7. Rail pressure is increased to 1400 Bar at high rpm – from above 2700 rpm and 30 mm^3 of fuel;
8. CR valve duty cycle is extrapolated to achieve 1400 Bar;
9. SVRL is set to 1400 Bar;
10. RP limiter map is set to 1400 Bar too;

The car has a little smoke from 3000 to 3500 rpm. Is that normal as I use AFR above 17,3 in smoke map? For the calculations of AFR I used fuel density 0,85 mg diesel/mm^3.

Здравия коллеге! У меня Opel Vivaro, и твоя работа мне очень интересна. Я пока что увеличил наддув и результат радует снижением расхода топлива и приятной ездой.
Hello colleague! I have an Opel Vivaro, and your work is very interesting to me. I have so far increased boost and the result pleases with lower fuel consumption and a pleasant ride.

my, maybe even useful, additions to the map set.
It seems to me in your EGR 15 * 15 that the air flow per cycle during EGR operation is actually registered. This should be necessary to identify errors in the flow mismatch.
I will try to reduce the amount of pre-injection soon, this should add pickup. On the WV 1.9 PD, a short and close pre-injection in the pump nozzle, and they are really more powerful.

Thank you @almetr for map pack update and for looking at my work, but I think that 7B794 is a part of X-axis of map 16x1 begins at 7B990 and in this table values are 1000. It is some kind of limiter which X-axis is rail pressure I think.

Да действительно, и у твоего и у моего ECU, в области дополнительного впрыска много коррекций по температурам и давлениям. И это выглядит слабо похоже на ECU по которому я учился. EDC15C2 Hyundai Tucson 2,0 CRDi 2004. И всё же шанс прибивать "впрыск после" у нас есть. Приложил фото где видно сходство в карте фазы дополнительного впрыска, и карте температуры выхлопа для разрешения дополнительного впрыска.
Мне очень важно сократить расход топлива до минимума, а это возможно только если увеличить отдачу от потреблённого топлива. Поэтому мой следующие шаг с помощью осциллографа увидеть существование дополнительного впрыска и конечно увидеть логику предварительного впрыска. Потом remap фаз впрыска.
Мне нравится твой ECU тем что нет опции поддержания заданного наддува, значит можно понадеяться на исправный vestgate, и увеличить наддув на малых временах впрыска. Ещё преимущество: малая область коррекций по температурам у фаз впрыска и количества впрыска, то есть не заблудишься. А может это и есть Азиатская комплектация без жёсткой экологии?
Мне придала уверенности твоя карта 770B2 Smoke Limit map, в Hyundai это совсем не так.
Будь осторожен с 78EF4Turbo Lim. Мне кажется здесь сомнительная логика в её назначении.

And really, and at your and at my ECU, in area of additional injection many corrections are on temperatures and pressures. And it looks poorly look like ECU on that I studied. EDC15C2 Hyundai Tucson 2,0 CRDi 2004. And however a chance to nail a "injection after" for us is. Attached a photo where likeness in the map of phase of additional injection is visible, and to the map of temperature of exhaust for permission of additional injection.
I am very important to shorten the expense of fuel to the minimum, and it maybe only if to increase a return from the consumed fuel. Therefore my following step by means of oscillograph to see existence of additional injection and certainly to see logic of preliminary injection. Then remap phases of injection.
I like your ECU that an option of maintenance of the set supercharge is not, means it is possible to count on in good condition vestgate, and increase a supercharge on small times of injection. Yet advantage: small area of corrections on temperatures at the phases of injection and amount of injection, id est will not lose way. And does it can and there is Asian acquisition without hard ecology?
Gave me to the confidence your map 770b2 Smoke Limit map, in Hyundai it quite not so.
Be careful from 78ef4turbo Lim. Me doubtful logic seems to here in her setting.

Hello friends!

I made xdf file for my Mitsu. Someone may need it if use tunerpro.

Hi to all!
I want to introduce you to my new project.
What is done:
- The smoker limiter has been completely reworked. The minimum AFR is around 17.9-18.
- The torque limiter is smoother and allows a maximum of 62.3 mm^3 at 3250 rpm;
- the DW is adjusted so that at 90% pedal position at 3000 rpm it ask for 63 mm^3;
- the EGR is switched off in software and hardware;
- reduced turbo pressure from 0 to 1750 rpm and up to 35 mm^3 diesel with purpose fuel economy. 35 mm^3 diesel multiplied by 0.835 are about 29.2 mg of fuel. The volume of one cylinder 487.5 cm^3 as air mass is sufficient to burn this amount of fuel without additional pressure. The rest of the map have stock setting. Cruising speed will create less back pressure and increase engine efficiency.

It's been tested. The car is going great. No smoke in the entire rev range. Pulls tight up to 3250 rpm.

My next project is transition from MAF to MAP smoke limiter, but a little later.


In your opinion, what else can i improve?
