If I use the "KFMDBGRG - Gear-dependent torque limitation to limit torque" map to limit torque in the first 2 gears do I have to use percentages of what KFMIRL/KFMIOP specifies as max load and not KFLDRX? E.g., if I put in 80% torque in first gear then the ME7 will use 80% of what KFMIRL/MIOP defines as max load and not KFLDRX? I am currently using KFLDRX to limit load and not KRMIRL/KFMIOP. Does the same thing hold for the map "KFTARX - Intake Air Temp Correction Factor for Specified Load Without Knock"?

KFMDBGRG gives absolute "torque" value (0-100%). Then it's compared against many other torque parameters (one of them comes from KFMIOP). Then ECU selects the lowest of all torque requests and that gives misol and milsol that are used later for throttle, ignition, fuel etc. calculations. If you want to reduce torque in FWD Volvo then i can tell that at around 330HP 80% torque is way too much at first gear  Factory is set at 55% in 250HP T5 and it burns tires pointlessly. If you have more power set it even lower. Reducing 2 gear torque is also very good choice. Setting it to 80% gave me around 0,5s better 0-100 time:) |

For my 260 HP T5, the factory setting was 100% torque in all gears (manual M66). I reduced it to 85% in 1st gear, but it was still too much on 1.0 bar of boost (stage 1). |

Been working on this awhile, i think its pretty close to being 100% accurate...
Edit: Forgot Engine speed limiter and fixed axis on KFLDHBN

what you guys do about maf scaling for the S4 maf ( bosch pn ending in 067, the 3.5" OD )
i have a car definitely reading high. 25.5-26 psi and its reaching 1600+ KG/H which in my opinion is not correct. it should be around high 1300's to mid 1400's
the MSHFMU curve goes to 1796
im pretty sure the problem is the HFM table being all 1's.
MAF is brand new and car is setup well.
Just curious as to what your experiences are, thank you.

Mine is on the ME9. Same 067. I converted the MSHFMU based on S4 bin values. HFM is set to all 1, same as the S4. It is reading correctly. |

What mshfm_w scaler are you use? I've got about 1400 kg/h (scaler is 0.1) on 1.6-1.7 bar of boost. XC90 accelerates in 5.5 to 100 kph. |

Allowing selective cylinders cut with redsol on gear swithing for 50WRHJ software: ROM:000506F0 loc_506F0: ; CODE XREF: sub_5053A:loc_506E4↑j
ROM:000506F0 jnb word_FD20.B_zwget, loc_50704 ; there was word_FD16.B_sgsred but this flag never touched in Volvo ME7
ROM:000506F0 ; 15 - B_mrakt
ROM:000506F4 movbz r4, CREDSTU
ROM:000506F8 and r4, #100b
ROM:000506FA jmpr cc_Z, loc_50704
word_FD20.B_zwget = word_FD20.5 bytes started from addr 0x506F0 should be changed from 9A 0B 08 80 to 9A 10 08 50 CREDSTU addr = 0x12D6F CREDSTU value should be changed to 7. REDMXSA addr = 0x12D73 REDMXSA value should be changed to cylinders count = 5 After this patch is applied you have to increase KFZWMN map values in high load regions. In such case there will be not enough ignition retarding when gearbox requests torque limiting and redsol mechanics will be used for torque limiting. |

Maybe someby have original for:
V70 2.4t 30729069A 1037359462 200hp autom.
I read with MPPSv16, was 512KB file, I didn't notice it and write it back. MPPSv18 read correct 1024KB...
XC60 30729069A 1037359462 200hp is different, Car runs fine, no DTC, but when take ignition off, ecu doesnt boot anymore before remove battery...
Thanks.

Simple implementation of launch control for 50WRHJ software. https://youtu.be/RvO9mls9-ZU#include <absacc.h>
#pragma MOD167
#define B_brems 0x20
#define nmot_w (XVAR (unsigned short, 0xF410))
#define wped_w (XVAR (unsigned short, 0x30195C))
#define vfzg_w (XVAR (unsigned short, 0x3029AC))
#define zwgru (XVAR (signed char, 0xF337))
#define redsol (XVAR (unsigned char, 0x3013F4))
#define redsol_my (XVAR (unsigned char, 0x30592C))
#define byte_301336 (XVAR (unsigned char, 0x30136))
#define launch_zwgru (XVAR (signed char, 0x2D000))
#define launch_wped_w (XVAR (unsigned short, 0x2D002))
#define launch_nmot_w (XVAR (unsigned short, 0x2D004))
void huge launch()
{
__asm {
calls 5, 0x50D24
}
if(wped_w > launch_wped_w && vfzg_w <= 128) {
zwgru = launch_zwgru;
if(nmot_w > launch_nmot_w + 400)
redsol_my = 5;
else if(nmot_w > launch_nmot_w)
redsol_my = 2;
else if(nmot_w > launch_nmot_w - 400)
redsol_my = 1;
else
redsol_my = 0;
}
else {
redsol_my = 0;
}
}
void huge redsol_select()
{
__asm {
calls 5, 0x053A
}
if(redsol_my > 0)
redsol = redsol_my;
}
Other changes: launch_zwgru const addr byte 0x2D000
launch_wped_w const addr word 0x2D002
launch_nmot_w const addr word 0x2D004
Call in addr 0xB2FA change it to DA 0E 60 A9
Call in addr 0xB4BA change it to DA 0E 44 AA

Hi! I've got S60 2002 2.0t B5204T5 engine with 180ps.
I read my ecu using MPPS v18 with boot mode.
Could someone check my file is it read correct, cause it look strange for me and winols can't find any description of car or checksums.
And if someone can help me to find some basics maps, like a LDRXN for exampe I would be very grateful.
