Simple implementation of launch control for 50WRHJ software.

https://youtu.be/RvO9mls9-ZU

Code:
#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:
Quote
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.

It looks bad to me.
Some parts look OK, but there are parts that looks messed up like VOLFO and Fadlab

Yes it is corrupt, but your file is 20kpsc.

That’s weird, cause I read again with galletto 1260 (using vag me7 definitions) and file is 100% the same as from MPPS. car is running fine on this file , but i don’t know if i can Tune this file.

The file you posted, isn't the actual file on your car. It's not been removed right.
I can get you a 20kpsc file and tell you where to modify, but it's no good if you can't upload to the ecu right.

Okay, now I understand. But it’s very strange, cause I sad I used galletto and mpps and both files were the same. Is it possible that this file is in my car? What flasher i should use, to be sure that file is read correctly?

I use Volvo dice cable over obd. There's no way that file is how it looks on your ECU, it's corrupt

Even winols tells you it isn't right when you open it.

The file is corrupt, if you notice on the ASCII hex representation, F is 0x46, but V is 0x56. Same for 'd' and 't'. There are bit flips. Oddly enough, always on the 5th bit.

Of course, what are you going to use it for on a manual?

On a manual just set redsol to 5 and then set it back to 0 once you're done shifting for flatfootshift.
