Thank you for your answer, but on S4wiki it says to scale back MAF, and it didn't make any difference.

Understood I should not touch MAP limit. Will try that.

However, my main question is, how do people tune to have a limit of load of 191? What are the sensors that are used to effectively calculate load?


You cannot run 30 psi on a stock ecu bin. As you mentioned/read there is an internal limit because 8 bit adress, which works out to ~2500 mbar, to get around it you need to do some asm stuff , which halves the resolution and effectively relieves the load limit too -  it has been covered in detail on the forum.  Load is calculated from many many things, you need to over the FR/s4 wiki in detail.

Cell values in IMX correspond the the numbers in DRL (linearization) DRL cells are output to wastegate.. so..

IF IMX is 90
DRL has columns 80 and 95,80 column has 70, 95 has 80....  you will get an interpolated result between 70 and 80.   It traces very similar to KFPED>KFMIRL>KFMIOP

Good starting point would be to take stock IMX and DRL values and divide them by difference of old gate versus new wastegate difference.

You could read through the feed forward LDR thread and extrapolate how to make it work via the information contained in there.

Thanks. Currently I have the feed forward pid. I totally understand that how it works. But as I see a little change at the system and the pid is not working properly. That's why I thinking to have the original PID and just tune it for the new N75 valve and the higher boost pressure.

Hi see attached images of tvub and temin used

Edit both temin and teminva are set to the same value

I played with those injectors extensively on my old 1.8 setup.

What dead times and Temin are you using for academics sake since we have the KRK that you are using?

Thanks to all here I was able to install my innovate WB and log with ME7 logger using a rear 02 sensor address.

Attached is a log with some light driving cruising, a 2nd gear pull to 3rd gear and some fourth. The cruising/light loads was a check to see if I was getting 14.7 at light loads cruise and i am (sometimes) but when I floored it after about 3500rpm the AFR dropped to as low as 8.5 even 7 (no black smoke billowing out of the rear of the car which would be expected at that AFR and seems to be pulling ok). Question is am i having a hardware issue with the WB i.e. dodgy sensor? NOTE: I did preform a free air calibration with WB prior to install or am i actually running that rich at WOT.

And just to be sure I took another log, same story (Attached)

Edited ME7L ecu file and added the following line:
;Name,    {Alias},                        Address,  Size, Bitmask, {Unit},        S, I,            A,     B, Comment
uushk_w, {O2SVoltageSensorWB}, 0x381116,    2,  0x0000, {WB-AFR} , 0, 0, 0.009766, -9.6, {}

Car is allroad 2.7t.
630cc injectors at 4 bar (Bosch EV14 and 044 fuel pump)
KRKTE : 0.05372
Targeting 0.75 or 11 AFR on wot (91 octane)
Yes file is locked WGDC file, I will be sorting my PID after I sort fuelling

Any help appreciated.

KFTSRL - #173A4 - its address for auto-script/setz'i lc/nls - not for this map (KFTSRL)!
Don't copy and write addresses without checking!

I search for stock method to make soft/hard cut.

No problems here on Win10.

Probably because I did not copy the "gui" file into the directory.
