Ugh, sorry about that, that makes things significantly more difficult I've attached what could work. I would like to log everything but my communication bus does not like too much data or I don't know what is the real problem.

Your KFMIRL and KFMIOP values are way off everything. Can you log these vaules at the same time? rl_w rlmax miszul mrfa mifa misol rlsol and off course RPM and throttle plate angle

Good point, At 6000 RPM and 90% load request He got low values in KFMIRL map
Need to get little higher values in this region,and in this whole row(bigger than LDRXN)

Yes currently I've the overboost. Yeah my turbo is not so fast/strong in lower rpm. What can I do with overboost problem? If I change the kfldimx I will get the intervention.

Is this a problem? I'm asking because the requested boost pressure is good at 6000 rpm. I don't need more.

Change IMX then do logs please, I want to see how that IMX have influence on intervation Yes you get enought boost, but that is bad tuned KFMIRL/KFMIOP that is not the best solution. You can expeeience problems in some condition

It isn't a problem as long as the requested boost doesn't drop off a cliff or do a crazy dance. It needs to be nice and easy, no big changes.

Currently I have this log. The strange thing is the lamda value for me when I checked the log. http://nefariousmotorsports.com/forum/index.php?topic=16562.msg128041#msg128041

Ok, so rlmax should follow the rlsol?

i don't have these variables to confirm, but everething point that there is intervetion. But without these variables rl_w rlmax miszul mrfa mifa misol rlsol I can't tell you what change in maps need to be done

Ok I'll do the modification maybe tomorrow afternoon and run a test. I will change only KFLDIMX. Do you have a proposal where should I change it to prevent the overboost and what should be the values? I've uploaded the current KFLDIMX table Thanks for the help you a nyet too.

Use values of IMX from this file i dont see here overboosting But what i see is bad tuned KFMIRL Your LDRXN at 5250 RPM is 175 % load --> 175% load and 5250 RPM tru KFMIOP in your map is about 90% tourqe request --> 90% tourqe at 5200 RPM tru KFMIRL in your map is around 160-165% Soo at first you are requesting 175% load, but tru tourqe maps ecu calculated to request 165% load. And there all shit start to hapen, it has nothing to do with your IMX
