Hello all,

I’ve got the 5120 Hack to work on 8N0906018H 0004, but still have the general questions below;

-   What exactly are the ASM edits achieving, if we are scaling the required elements in the config, why are we needing to edit the code? Also if we are editing the code why is it not
        possible to edit the 2560mBar limit to a greater value? Resolved see further down trail

-   How do the VCDS edits work, is it just a report x 2 edit or something else? Resolved see further down trail

-   4Bar MAP sensor values, using the attached pdf I come out with; Resolved see further down trail

        Min Pressure   50   Min Voltage   0.3           
        Max Pressure   400   Max Voltage   4.7           
                        
        DSLGRAD =   79.54545       For 5120 Hack divide by 2 =   39.77273
        DSLOFS =           26.13636       For 5120 Hack divide by 2 =   13.06818

        Yet when using these values the car doesn’t go very well, they are clearly wrong.

        How are the DSLGRAD / DSLOFS of 437.5 / 31.25 values arrived at using the below formulas and specification PDF?
 
        DSLGRAD = (MAXPRESSURE - MINPRESSURE) / (MAXVOLTAGE - MINVOLTAGE) = xxx.x
        DSLOFS = MAXPRESSURE - (DSLGRAD * MAXVOLTAGE) = xx.xxx

In the log & bin attached I’m limiting the boost via KFLDRL, while testing, which explains the squirmy boost profile.

Thanks

Am I reading the PDF wrong?

Using values from PDF;

DSLGRAD = (400KPa – 50KPa) / (4.7V – 0.3V) = 79.54    5120 hack /2 = 39.77
DSLOFS   =         400KPa - (79.54 * 4.7V)     = 26.13    5120 hack /2 = 13.06

Even using mBar it still comes out different from the established working values?

Min Pressure   500   Min Voltage   0.3         
Max Pressure   4000   Max Voltage   4.7         
                  
                  
                  
DSLGRAD =   795.4545455      For 5120 Hack divide by 2 =         397.7272727
DSLOFS =   261.3636364      For 5120 Hack divide by 2 =         130.6818182

How are people getting the below from the PDF?

Min Pressure   420   Min Voltage   0.4
Max Pressure   4100   Max Voltage   4.646

PS

Any thoughts on the other points?

Ahh,

I get it, you use the graph on the right hand side of the PDF not the table on the left, would have been easier if I could speak German (the whole thing would be easier if I could speak German).

Thanks

= you give the ECU for example 500mbar corresponds to 1000mbar Otherwise higher processing is not possible.  (ASM changes are inevitable)
disadvantageous you change the resolution a little bit ,

from ori ECU files:
DSLGRAD
stock map->541.00
3bar map ->658.81
4bar map ->875 

DSLOFS
stock map-> -16.41
3bar map -> -63.52
4bar map -> 62.5


->   How do the VCDS edits work, is it just a report x 2 edit or something else?
= yes the formula has to be edited, similar to edc15 16 only that you have to do it in code

 

You completely misunderstand the nature of the limit.

How about enlighten yourself with the info that's been posted on here time and time again.

Somone pointed me in the right direction.

Without compling the whole thing you can't just use two registers next to each other to store a number larger 255.

If you were just to use 0.1*255 instead of 0.01*255 to represent boost, the resolustion would go down to 100mBar.

Lost me now, if it's 16 Bit a value of 65536 can be stored.

Where is 2560 limit comming from?
