S60R with K24 hybrid turbo and 630cc Bosch injectors. Stock MAF has not enough range, after 5700 RPM shows 1240 kg/h. Owner will install more performance fuel pump (which is also finished) and MAF from RS4.
another thing i have found is desiring more fuel pressure on spool up of the turbo to replicate a 1-1 ratio like a car with a fuel return system

Have you ever tried a cross between feed forward and the method volvo uses for boost control, i find it much easier to manipulate and keep the resolution I desire.
Yes, I tried this approach on my car. But I want to automatize this process with application and in memory KFLDRL map. Unfortunately this work isn't finished yet.

i personally don't rescale KFLDRL and KFLIMX unless the car has a aftermarket wastegate. if the car is using one ive had good luck with the LDPRID tool shared by PRJ i believe it was. It can be picky on the data you input but seems to work well.


the method i use for cars utilizing the factory wastegate is provided in the .ols ive attached. i have found it runs off the map in KLFIMX then is DC is controlled Via KFLDRL. a few down falls I've found with this method is KFLDRX is utilized as a load cap rather than a desired value. This will piss off the I factor so i will Numb it using a few maps in the LDRPID folder. I personally like to use this method as it will maintain as factory until you exceed your set boost pressure using KFLIMX.

i just built this on a stock tune to display this method for you. Ive attached a log of a previous tune i had done utilizing, as well as using the LDRPID tool

Thanks.
tmotlin for your software has 0x30163A address.
Looks like you have 950cc injectors and nonstock turbo. And nonstock intercooler too)
Why did you lower your load request after 5700 rpm?
Which fuel are you use? I see 6 degress knock retard on high RPMs.

I lower the load request with stock turbos to chase the boost falling off in the high rpm.

The log with semi feed forward is using a hybrid k24. I had lowered ignition timing after this log to make up for the knock this was using 91 octane from the states.

The log with feed forward using the ldrpid tool is using a old majestic turbo that was offered ages ago

Manual. Thanks a lot!

prometey1982 did you find RAM variable for Misfire Counter in your 50WRHJ?

I tested 5120 hack with boost precontrol. It works more or less fine. Just need some tuning of KFLDRL map in high regions. And unfortunately can't do more test runs at the moment due to snow. I've got 1200 kg/h of air on my hybrid turbo.

what was your approach on using this tool. ive usualy had really good luck copy and pasting KFLDRL with some smoothing by hand. i start by setting CWMDAPP to 08, Then logging a fixed dc from 30-90 percent above 70 percent throttle in KFLDRAPP. once complete the logs i set them in a seperate folder, open the folder using LDRPID tool. i then find where the turbo makes desired boost pressure Usually around 4000rpm with a hybrid k24) and copy 8 sets of HPA that the tool loads from your logs at that rpm where you had noticed from before, pasting them into the HPA axis of KFLIMX, smoothing them to be absolutely linear. once complete i change the precision to 0 ( the tool wont allow any decimals) copy the HPA axis over to LDRPID tool. doing the same with set wgdc to get the z axis of KFLDIMX ensuring its absolutely linear and bring these values into the tool, now its time for the KFLDRL axis i copy over the 1x8 of what populates KFLDIMX and paste into Percemt charge of KFLDRL and ensure that ill have the resolution i desire in the last two colums ( i personaly like to keep a 5 percent change in the last 2) then i press generate, copy and paste into KFLDRL. then using 3d i pick up all the holes and smooth it by hand. before flashing i study the set wgdc logs and ensure that the KFLDRL i have set wont spike boost terribly.

it takes some time but seems to work pretty well in my experience
