Hehe, you made a different experience?

I tried a lot the past 15 years. Four Spray Dekas work very well on these Volvos. My experience.
Sure, you must do more than shifting TVUB up and down, but i guess you know Smiley

Not just about that, like people mentioned, they are very temp influenced for one , and very unlinear on low and high pw, but if it works it works, but I wouldnt say that they are better than any kind of bosch injectors, since they come with any size , neck or spray angle/port you need. Maybe they are made for volvo's  Cheesy

I'm using Denso 550cc injectors from Subaru WRX STI knowns like pink. They have longer dead time than green injectors but works fine for me. And for my power is more that enough. But I want to get 400 bhp from my engine and 0-100 around 6 secs. I'll happy if I'll get it from XC90 with 2.5T engine.

Some more investigations. There is a function which calculates lamfa_w variable. This variable clipped by hardcoded value 0x1000 which means 1.0 lambda value.
But code can be patched. Just replacing of 1000h with 1100h in three places allows to increase lamfa_w value to 1.1. I didn't do road tests maybe there are limitations if different places but they also can be found.

Hi everyone. In advance, I want to thank the users and founders of this forum. I emphasized almost all the knowledge from here.

My friend and I are trying to set up my car. In this case, full noob. But something was figured out. Car Volvo S60 2.3T5 2001. Of the rework, only full exhaust 3" and fuel pump walbro 400lph.
Below I will lay out the cards that I found. And modified *.bin.

As a result, it turned out to increase the boost to 1.3 bar and 0.85 bar to the redline. The KFMIRL map recalculated the maximum LDRXN. KFLDHBN was not edited. Because use standart intercooler. Increase of temperature by 4 gears 100-200 km/h from 15 to 45-50 gr.C.
The ignition angle at full load was also increased. And in some places they increased the ignition angle at the average load (this is just an experiment) (KFZW).
Raised idle speed to 750 rpm (NLLM).
Catalyst Health Check (CDKAT) is disabled.

But there were problems. Afr is always 14.7. Until the KFLBTS map is enabled. TABGBTS activation threshold. If we disable FBSTABGM it will be fixed? Then the engine should work on the KFLBTS map always?. LAMFA I have everywhere "1." This map probably doesn't make sense to adjust.

We also tried to edit the Delta Lambda (DLAMOB) parameter. Set the minar value - enrichment completely turned off. AFR is always 14.7 from 2000-6500 rpm. Got it back.

I very much ask for help in solving the problem with afr.
KFLBTS found, but there is a problem with the axis.
TABGBTS, FBSTABGM did not find.
IDA has not yet been dealt with.

p.s. I'm ashamed of my bad English...

And this is really darn fast.

You need to update LAMFA map values. There is my LAMFA map.

Does lamfa match the actual value?

Yes when modelled EGT less than TABGBTS.

TABGBTS, FBSTABGM did not find.
TABGBTS - 0x1EA9E - 16 bit. Factor 0,019531, offset -50
In your file 950 grad C.

FBSTABGM - 0x1EA7C - 16 bit 4x1. Factor 0,000031. Factor for X axis 0,019531, offset -50,000000.

KFLBTS - axis for load is at 0x1EA86. 16 bit. Factor 0,023438.

I've tried to modify a code in such way and it didn't work. But lamfa_w value was lean that 1 if LAMFA map contains lean that 1 values. It means that hardcoded value is somewhere else. Unfortunately I have a few time for continue investigations.

Thanks. The FABSTABGM map contains all "1". But AFR doesn't match KFLBTS. Except for the maximum values.
Today I'll fill in the modified KFLBTS and take off the logs.
Changed the ignition angle a little more. I'll try to squeeze everything out of standard components...

Has anyone tried regulating afr via DLAMOB?

From NefMoto Wiki:
http://www.nefariousmotorsports.com/wiki/index.php/LAMFAW_7.100_(Driver%27s_Requested_Lambda)

DLAMOB: Engine speed sample points: Group characteristic SNM06GKUB
Map values: All are 0 ---> no additional enrichment during overboost
In the map, delta values are entered + 0.1 ---> lamfa = lamfaw – 0.1!


Setting all values ​​to the minimum of 0.0469 does not change afr. Always 1.

It's for overboost. But overboost is disabled in our BINs.
