After applying the previous settings to the 5120 hack map, it all looks good, I'm restricting the boost via KFLDRL in a blanket fashion which accounts for the squirmy boost at present.

Have to fit the 4Bar MAP & uprated rods now Smiley

Some useful files, use at your own risk.

.bin updated with minor edits 29.01.2021

LDRQ0S was divided by 2. now multiplied by 2

KVLAD was divided by 2. now multiplied by 2

31.01.2021

Changed both LDRQ0S & KVLAD back to divide by 2 as after a test run the car didn't run well at all.

Look at post of 05:34:02 AM 1st Fed 2021 for .bin with 4Bar MAP sensor Bosch 0 281 006 060/0 281 006 059, 550 injectors with 4Bar FPR & hybrid turbo.

Hi IWay.
Some issues in your file:
LDRQ0S must  Multiply by 2 , you divide it.
KVLAD must  Multiply by 2 , you divide it.
FHOKH - Set to 0(in addition to the fho_w ASM division) , here i'm a little confuse. you divide it with 2
You put KFPLGUB in 5120 category but is not modified. Do you think it must divide hpa axis with 2 ? I found it in other files unmodified!

Tao13,

Thanks for your diligence in checking my settings, always a good thing to have a second set of eyes look at something.

Don't pay too much attention to my XDF layout as it's a bit of a mess and needs tidying.

Yep, those are the values I'm using, they are in the spreadsheet above. I found them by searching for the original posted values for other box's in the HEX of the .bin, there are 3 others of the same value, don't know what these do (in the spreadsheet)?

I had taken the multiply or divide from the s4wiki - https://s4wiki.com/wiki/Manifold_air_pressure:Rescale_project

LDRQ0S must  Multiply by 2 , you divide it. I've changed this

KVLAD must  Multiply by 2 , you divide it. I've changed this, looked at my log from yesterday and its reporting correct air mass (210 g/s), I'll see what happens now it's changed

FHOKH - Set to 0(in addition to the fho_w ASM division), here I’m a little confuse. you divide it with 2 s4Wiki - Divide by two or set to 0, I divided it, when I'm happy with the rest I'll try setting to 0 and see what happens

You put KFPLGUB in 5120 category but is not modified. Do you think it must divide hpa axis with 2 ? I found it in other files unmodified! Problem with throttle plate only opening to 50% see below;

Mr Boobietrap wrote,

"My throttle plate was not opening to 100% on WOT.
Turns out there is a map called KFPLGUB which is used instead of ambient pressure for calculating pressure ratio across the throttle plate (used in throttle maps) if CWPLGU = 0.
Apparently on most cars CWPLGU = 1, hence this map is not mentioned in the 5120 hack threads, but on mine this was set to 0.
I think the solution is to either divide both the axis and the table by 2 or change CWPLGU to 1. I've done both just to be safe and now the throttle behaves correctly."

Setting CWPLGU = 1, appears to have worked with out changing the KFPLGUB map


4Bar MAP should arrive today, might get the chance to install today & test if not tomorrow, I'll post how it goes.

Before yesterday i worked with 032hs file starts by justinw.....it works ok but with some issues about idle.
It is a greate difference between 032hs and bam file. I used the same modified tables for load/torque/boost/timing/fuel, but bam 5120 hack file is very aggesive, like throttle is forced. This happend after made CWPLGU = 1, because confirm with it =0 the throttle is cut from 65 to 40% and the boost is half like it must be.
Yesterday i modified my BAM stock file with 5120 hacked modifications trought comparation with other files and xdf's, because i declare sincerly , i don;t know asm.
Today like as a connection, you posted the file. I confirmed the modification is ok. I hope (because i don't know asm)  it doesn't exist some other hidden modification in file for 5120hack, than that 1013 divisions.

Hi IWay. Do you tried FHOKH - Set to 0? Something happen? What value do you use for KISRM?

tao13,

Changed both LDRQ0S & KVLAD back to divide by 2 as after a test run the car didn't run well at all.

Haven’t tried FHOKH - Set to 0, KISRM set to 0.065002.

Installed 4Bar MAP sensor and took for test drive was OK-ish, the only things I changed from the working 2.5Bar MAP sensor were the DSLOFS & DSGRAD to account for the change in MAP. I also changed the KFLDRL, see attached pics.

All appeared well but reviewing the logs the WGDC was stuck at 5% on the 4Bar config?Huh?
Might be something peculiar about KFLDRL going up in single digits?Huh?
Going to test with the same KFLDRL and see what happens.

KVLAD must multiply by 2 like wrote in txt project file not devide!
You must calculate dslgrad and dslofs for 4bar map sensor and after for 5120hack must devide both with 2.
What map sensor do you have? Witch code?

About that 2 tables in my opinion they are shit, doesn't had any effect to the car runing and logs and turbo and throttle? So without effect for me!

It makes a big difference, I know this from experience. Particularly on part throttle.. and that's with standard turbo/wastegate.

It's easy to set these tables after making a run with 0% DC

Thanks for you opinion, but sincerly for my custom settings for a garrette wastegate and a gt2871, doesn't matter these 2 table how are set......the car run and log the same! i adjusted from 0 to 100% these table and without effect!

Appears to all work now with 4Bar MAP sensor Bosch 0 281 006 060/0 281 006 059.

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

Bullshit.

But if your car is tuned like shit anyway, then of course you don't notice when throttle is going bananas.
