You may also want to log ps_w to make sure you aren't maxing it.
Under WOT ps_w is 2559.96

you might need to underscale your MAF if you are.
Could you explain?

heh.

5120 or underscaled MAF time.

Hi again!

Guys, thanks a lot for your hints and notices!

I've rescaled MAF calibrations and now rl_w is almost equal rl and also never bigger than rl. Because of this Requested AFR is pretty close to Actual AFR. But I'm still overcoming ignitions retard and I noticed several things:
1. Most of the ignitions retard happen when coolant temperature is less 80C;
2. In some area when rl_w > rlsol_w when WG is closed but turbo began spooling and ignitions retard happen.

So what would be better to smooth the difference with rl_w and rlsol_w by rescaling MAF calibrations or with IOP/IRL rescaling at these areas?

It seems related to optimal efficiency KFZWOP and something like that.

not an issue

not an issue, unless you are WOT.

No. Please study up on torque based systems...

Hi Guys,

Guys, I have to ask for your assistance again. I have remade many things but I'm still trying overcome ignition timing intervention. I haven't managed to find out with nature of the this issue. It seems to IOP/IRL issue.

DD, nyet, Rick
- guys could you look through my WOT on 3rd gear log file and point me a little hint? I just stuck. Sad

Thanks in advance!

In addition: In my understanding I need to reduce IRL with different efficients ETADZW*, DZWOLA* etc.

Have you tried disabling the torque intervention? That way you'll see pretty quickly if you kfmirl/IHOP maps are screwy

Yes, I've tried and I didn't have timing interventions. Yes, I know this is the answer for my question but I can misunderstand that's why I asked the assistance from guru.

I think I've found the issue my rl_w is always lower then rlsol_w so because of this my IOP most of the time is lower then IRL therefor I need to upscale back my ps_w in order to make rl_w higher.

Am I rigth?

Hi Guys,

Thanks a lot for your assistance!
The issue was fixed.
I've rescaled ps_w and rlsol_w and adjusted IOP table.
