Title: 1.8T BFB - more power needed Post by: roman_tyk on April 19, 2013, 07:31:26 AM Hello everybody!
I bought audi b7 2005y with engine 1.8T BFB 163ps. In the beginning i removed second lambda and catalyst from software. For tests i modified only LDRXN's maps (up to %=145) but from vag logs it's seems that i should change injectors to 320cc (stock are 280cc) and i am getting inj time higher then 21ms. logs: http://vaglog.rtnet.pl/roman_tyk29_122674.html http://vaglog.rtnet.pl/roman_tyk29_122673.html I am planning to advance my ignition, can i copy all KFZW/KFZWOP maps from BEX engine version (320cc and 190ps)? I am wondering because % axis on my ECU is scaled to 140...and in BEX it's scaled to 160. I think i can't change axis because it's common for a lot of another maps, am I right?

As you can see, you have 0,9 (~13,2) a/f until 5300-5400 rpm and then goes to .73(~10,7). Change LAMFA (>850C) and KFLBTS (850C>). Title: Re: 1.8T BFB - more power needed Post by: roman_tyk on April 24, 2013, 01:07:26 PM I would like to start my tuning adventure with changing injectors to bigger one. Then i will remap A/F ratio as you suggested. I am planning to buy K03s, the best option for this will be 320cc injectors or 440cc?
For 440cc do I need to change any other maps then KRKTE/TUVB/KVS? My stock values now: KRKTE=0.06904 KVB=304.69 TVUB 1.4071 0.8784 0.6114 0.4459 0.3311 Title: Re: 1.8T BFB - more power needed Post by: hipeka on April 25, 2013, 07:00:39 AM I am planning to advance my ignition, can i copy all KFZW/KFZWOP maps from BEX engine version (320cc and 190ps)?

Have you try to compare values? Most of those kfzw maps are quite same at lower loads. Can you post that BEX .ols file here? Title: Re: 1.8T BFB - more power needed Post by: roman_tyk on April 25, 2013, 07:26:21 AM Ok guys i rechecked BFB maps and BEX maps, if i want to change injectors from BEX 320cc@3bar
Should i change those (http://s24.postimg.org/4lthz293l/krkte_BFB.jpg) (http://postimg.org/image/4lthz293l/) to: (http://s2.postimg.org/42pnjh4ed/injectors_maps_bex.jpg) (http://postimg.org/image/42pnjh4ed/) BFB 280cc@3bar KRKTE=0.06904 KVB=304.69 TVUB 1.4071 0.8784 0.6114 0.4459 0.3311 BEX 320cc@3bar KRKTE=0.06161 KVB=304.69 TVUB 1.3510 0.8224 0.5554 0.3898 0.2750 Why KVB for both is the same? Title: Re: 1.8T BFB - more power needed Post by: roman_tyk on April 25, 2013, 10:22:35 AM I think the problem exist on my KVB maps locations....
What is stock KVB value for BFB and BEX? I am searching for (8bit): 62/64/66/68...

I reviewed about 10 differents 1.8T definitions map. There is always convention like this: Examples: 1. 32768 32768 00753[krkte] 25933 00004 00103 00148 2. 32768 32768 00944[krkte] 25933 00004 00157 00177 3. 32768 32768 00928[krkte] 25933 00004 00103 00176 On my BFB I found: 1. 00150 00125 00622[krkte?] 25933 00004 00157 00177 For krkte 0.10367 there should be 933(dec) with factor 0,000111, i don't have this value on my BIN. But for factor 0,000167 i will get krkte=0.10387 Which factor should i use? Is there any way to easy find out krkte? Title: Re: 1.8T BFB - more power needed Post by: SVSPORT on May 04, 2013, 09:42:06 AM Here your KRKTE
Title: Re: 1.8T BFB - more power needed Post by: roman_tyk on May 04, 2013, 11:22:44 AM Thanks SVSPORT i found it few days ago, it was problem for because i was looking for value with factor 0111 and here was with 0167.
Today i successfully removed catalyst: (http://s23.postimg.org/bq2647biv/downpipe.jpg) (http://postimg.org/image/bq2647biv/) (http://s23.postimg.org/5ewynsaaf/downpipe2.jpg) (http://postimg.org/image/5ewynsaaf/) and installed downpipe 2.75. I collected logs and seems that turbo is spooling up earlier :) and it's blowing about 0.85bar in stock: My vagcom logs: http://vaglog.rtnet.pl/roman_tyk29_125071.html http://vaglog.rtnet.pl/roman_tyk29_125070.html Nice mod :) In next week i am changing injectors to 320cc@3bar black from BEX 190ps. TVUB/KVB/KRKTE already found. Title: Re: 1.8T BFB - more power needed Post by: roman_tyk on May 09, 2013, 11:16:28 AM Hello everybody!
I changed injectors to 320cc@3bar, in stock injection time decreased to 14ms. So i uploaded my program (ldrxn, kfmiop, tagbts...->modded) http://vaglog.rtnet.pl/roman_tyk29_125702.html http://vaglog.rtnet.pl/roman_tyk29_125703.html http://vaglog.rtnet.pl/roman_tyk29_125704.html Now i am playing with fueling, in the end of rpms and max load i want to hold lambda in 0.78-0.8: (http://s12.postimg.org/q1af85cbd/KFLBTS.jpg) (http://postimg.org/image/q1af85cbd/) Is it good for this engine and k03? Title: Re: 1.8T BFB - more power needed Post by: Kacza on February 05, 2016, 10:09:22 AM Hi. It is enough that you write KRKTE, KVB and TVUB from map BEX to map BFB and injections were calibrated OK??
Did you additionally correction? |
