Title: KFLDRL and KFLDIMX axes Post by: ama11deus on September 11, 2022, 04:24:21 PM Due to some recent modifications I did to my car, I finally decided to increase my boost. I also noticed some overboost (0.2 bar) when spooling up my turbo (I assume its because of the larger intake volume consisting of a FMIC and bigger pipes vs a SMIC and small piping).
So naturally I wanted to fix the boost spike first. I am looking at two maps: KFLDRL and KFLDIMX. My (noob) questions: 1. My KFLDIMX plsolr_w axis caps out at 546.9 mbars (img1)of boost and that makes sense since my engine is a 150hp 1.8T and thats how much it makes at peak boost. So from my understanding in order to more boost I should scale the axis accordingly(among other things), for example change the last value to 700 mbars. Is that correct? Can I just change the values to 0, 100, ... , 700 ? 2. When I make plsolr_w a seperate table and I increase the number of columns up to 11 (!!). The next values make sense. (see img 2) Is that purely a coincidence? Should I be changing something there too? It just looks too good to ignore. Perhaps the axis is defined incorrectly? 3. From what I have seen KFLRDL ldtvr_w axis goes from 0 to 95 and that would make sense. But the one I have found goes from 20 to 70 (img3)? Is that just blatantly incorrect or is it somehow because my engine had the K03 turbo and somehow only expects 70% DC or something? My question is can/should I change the values to 0 - > 95? 4. What is more concerning is that the ldtvr_w axis I defined is also very weird when I make a table for it and ask for 16 columns. It goes up to 130. (img4). Is it also a wrongly defined axis? 5.When I view the .bin file in a Hex Editor I see a lot of space filled with FF. Is it safe to assume that those are empty memory? For ex. from around 0xAB240 to 0xFFFE0 (which is a lot) everything is only FF values. If anyone would be so kind to answer my questions or even(!) look at my .bin to confirm the validity of those adresses, I would be extremely grateful. ldtvr_w - 0x1347A X*0.005 plsolr_w - 0x1F254 X*0.039063 KFLDRL - 0x1EF00 X*0.005 KFLDIMX - 0x1EDAE X*0.005 Title: Re: KFLDRL and KFLDIMX axes Post by: gremlin on September 12, 2022, 02:31:48 AM If anyone would be so kind to answer my questions or even(!) look at my .bin to confirm the validity of those adresses, I would be extremely grateful. ldtvr_w - 0x1347A X*0.005 plsolr_w - 0x1F254 X*0.039063 Wrong assignments. Real axes are ldtvr_w - 0x1F254 * 0.005 plsolr_w - 0x1602C * 0.039063 Title: Re: KFLDRL and KFLDIMX axes Post by: ama11deus on September 12, 2022, 10:22:30 AM Thank you very much! Now the tables make sense and I'm more confident in changing the values.
