Hello!

I made some changes, but I couldn't find the SOI maps. Where should I look around and what factor to apply?

I also didn't spot any other rail limiters, and have looked for 13500 values around other rail maps.

I should give it a try soon!

Many thanks!

6 maps 1x1 rail pressure limiter
Soi with pilot inj
Soi without pilot inj
Soi of pilot inj
factor for soi maps 0.023438

thank you very much! I will look at this.

So today I tried the new mod file. But Im still getting the same problem. Just a little gain from stock file...
I made some more changes, trying to inject 76mm3 smoke map allowing large fuel quantities, but no smoke at all and no power.
I may have something limiting my fueling.

Can some of you give a check on the loaded file?

72460 and 72730 little, 70mm -->75mm +5%, 70mm-->80mm +10%, about though so.
72d04 - bad! mod return ori!
78450 - mod return ori, map start car.
78690 , 78692 - return ori,
78b5e - increase will lead to an increase in fuel consumption, better only increase axis 1000 and 1050.
78efc - You can not touch

Duration is wrong, so you are injecting only about 70mm^3

Go here and download attached Stilo ols file:
http://www.ecuconnections.com/forum/vie ... ilit=stilo

Open it and you will found much of maps and locations. Then, open your file, view both hexdump files in text mode, 16-bit mode and decimal (some on/off bits are 8bit) and compare Stilo maps with your hexdump. Firstly, start with EGR map which is very easy to find, than go forward. Look for similar values/patterns in Stilo maps and find them in your file. With that method, you can find all relevant maps that you need, including SOI.

Some maps that you modified are not needed to modify.

For basic remap (without car hardware modification), you will need to modify:
- PGW drivebility map
- BEG torque limiting
- BEG smoke limitation map
- EXT fuel quant. limit. dep. on temp
- INJ duration, both maps
- INJ basic map, start of main with and without pilot
- LDR open loop dc setpoint eco, sporty and transient map
- LDR boost pressure setpoint limiting map
- LDR basic boost press setpoint eco and sporty map
- Boost control, upper absolute setpoint limit

Also if you want, you can play with common rail pressure to achieve better EOI, than need to modify 7 single values and 3 maps.
