Yes, more straight. As in completely "straight". As in subtract your lowest value from the highest value of the hpa axis, and then divide that by the number of cells between them. Start on either end of the axis and add/subtract those values to get the stepping between the cells equal. Like SB said it does not have to be like this, but makes it easier to translate between the maps. This isn't going to really change your boost response, it's just simplifying part of the process. HTH.

Thank you for your clarification, now I have understood what I should do. Greetings, I will try it |

ok I think this is what you wanted to tell me. I'm going to generate a new drl with all these changes and I'll try

I still have that instability up to 4k, in all the files generated by the tool has happened the same, I think the tool is doing its function, but there is something in my calibration that should be adjusted in that area, here are the screenshots of such maps as they are now, and two wot tests. It seems that from 4k begins to stabilize, q2 begins to fall in that area, I really do not know if I should lower the values of q2 before 4k. it is currently stock. I show you drl generated by the tool, linear imx, and lddimxn to zero. Thanks for the help

logs need ldtvr_w.
I'd still increase your request more at 2500 rpm and add more to q2.

what amount do you suggest that you add to q2? I add it to the whole map? or just a certain area I really thought that I needed to remove q2 to lower the oscillation, but I was wrong. really what does q2 do? |

i actually agree, less q2 will help remove oscillation, and it will expose where you need to fix up IMX |

I have been able to see in several calibrations stock for 1.8 k04, that q2, q1, q1st etc are around between a 30/50 lower percentage. my turbobe k04, although it is not the same model of 225, maybe it would be good to use all these maps?

difficult to tell anything without ldtvr_w, but I really think there's not enough q2. I would add some (15-25%) in the first two columns from 2k - 4k and smooth it out. |

Take note of how much your boost request is changing as actual is approaching requested. This needs to be flattened out a bit otherwise it's going to be really hard for the PID to try to control it.

you mean, what should I do, increase more demand in that area? I know I'm trying to control a turbo that charges me fast and soon, but I would not like to boost so low to protect the clunch, rods etc, and I really thought that the pid is there to control this phenomenon. going back to the log, then you see progressively necessary incremental there, and now that you have the variable that you needed to see, you can advise me on imx or something else that I need to adjust. thanks for your help |

I'd try bringing IMX up a bit.. I don't see a lot of P or D activity in the area where you are underboosting, which means I is a bit low there.
They only come in long after the underboost to correct the I which is a bit low.
Unfortunately, increasing IMX will probably get you a bit more overboost, but it might help the underboost oscillation initiation.
I understand your concerns about surge, and they are not unreasonable, just realize it is very tricky to PID control a turbo during spool.
