Hi, guys!
Today I did some small logs to check if my load isn't limited by anything. So far so good, but I have question regarding rl variable.
rlmax_w, rlmx_w and rlsol_w follows maps as expected but I kinda am curious about rl. In my logs it is higher than all the others. Would that indicate something or am I just paranoid?

rl is created in BGSRM (haven't looked into this module yet). Any more insight into this whole module and how rl is created?

P.S> I've attached graph in question

Found one more thing: injectors! They are directly affected by rl ir vice versa

Lambda correction is also going nuts...

stock MAF kinda not linear... Dunno if it is ok

Your MAF is likely reading high. Might want to scale it down a bit.

Nyet, my maf is STOCK. Also lambda correction goes up and then down without any reason. O2 sensor is brand new. Any ideas if bad maf could be reading HIGHER than supposed to? Shocked Most of the times if they go bad they start to degradate and can't read high enough....

I checked the log and only find some WOT up to 3000rpm in 3rd gear.
  Huh

your HFM read is not filtered, look at ml_w to get it more linear.

Did some better logs... In second and third gears wot. Please look at my WG duty cycle.... And also injector duty cycle is way to high... Stock torque, but bigger injectors now result in same DC.

Changed FPR today (was giving a little bit too low fuel pressure). Nothing changed! One more thing that started to happen: After about one hour of non stop drive my car started getting random misfires on wot. Any ideas guys? Im attaching some small logs (in second gear though).

misfires on wot.

Same old recommendations.

plugs, coilpacks, POS (if you have them).

Generally can't diagnose misfires from logs :/

plugs and coilpacks <- brand new

what is POS? I know only one definition of this and it isn't related to cars Cheesy

P.S> Nyet, could you elaborate a little bit about wastegate before lin vs wastegate after lin in my logs? isn't before lin too low?

I have no logs because I have a boost gauge (makes things easier)

Err. It is PID output before/after KFLDRL :/

Depends on your PID tuning approach.

Thanks, now I see... Btw PID is completely stock as is turbo (K03). Yet I can't understant why wastegate DC isn't at 95 whenever I press gas pedal 100% and load haven't reached the target?

WGDC maintains boost pressure actual to target, not load.

Desired load is used for load realization. Throttle angle and boost pressure are calculated to meet filling requirement, but there is no actual vs requested.
