Hey all!
So the long story short is that I CAN NOT hit even 1 bar with K03 no matter what I do... I've tried logging today and results are attached (please open them in ecuxplot). AFR looks OK. No knock, no retard. Wastegate duty cycle is interesting... at WOT it doesn't go lower than ~50%. Also desired boost maxes out at 0,72 (how the hell it is desired only 0.72 when my LDRXN whole map is 200s and KFMIRL maxes out at 195???). Also Lambda for part protection at WOT in second and third gear enriching mixture upto 0.82 (but with LAMFA I already enrich mixture to that at wot). Also ChargeLimitEngineProtection is going down at WOT...

Please help! Smiley

P.S> logs are done from complete stop to third gear (as you can see by RPM climb)

Can't tell a whole lot from your log. It is not LDRXN or any part of LDRLMX (i.e. ldrlms, ldrlts) as rlmax is not limiting rlsol.

I could log other variables, just tell me which  Wink

"hitting"? Forget about logging actual boost if you can't even get *requested* boost anywhere useful.

Please use the filter feature of ECUxPlot, it is impossible to see what is going on Sad

Do a FULL WOT 3rd (or 2nd gear) pull from low rpm to high rpm.

make sure to log gear and accelerator pedal position, and graph using RPM as the x axis, not time.

Did you modify KFLDHBN?

It's not KFLDHBN as rlsol isn't being limited by rlmax.

rlmax does follow ldrlts for part of the log but it remains above 180 specified load.

I think that it's KFMIOP limiting KFMIRL via mimax_w -> mifa_w/mifal_w -> milsol_w.

His KFMIOP load axis maxes out at 145 with a max torque value of 45.

Ok, gonna do full pull and log acc pedal, gear, rpm. What else to log? requested boost? wastegate dc? afr? Wink

Yes, I even tried to up KFLDHBN a little bit... Still no result

OK, gonna be back with the results tommorow Smiley

P.S> Question about KFKHFM map. How does it fix maf data? If for example coefficient is 1.1000 will ecu enrich mixture or make it leaner?  Undecided

An IOP that is too low will NOT result in limiting req load...

My me7logger couldn't find mimax_w, mifal_w, milsol_w (only mifa_w is there) Could someone help me out with finding them? I've attached bin file

How about MISOPL1_W?

Take a look at the relationship of the variables I posted starting in MDMAX.
