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.htmlhttp://vaglog.rtnet.pl/roman_tyk29_122673.htmlI 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? |

You have to calibrate the A/F ratio, first.
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>).

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

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? |

Ok guys i rechecked BFB maps and BEX maps, if i want to change injectors from BEX 320cc@3bar Should i change those  to:  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? |

@SVSPORT really thanks for comparison.
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?

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:   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.htmlhttp://vaglog.rtnet.pl/roman_tyk29_125070.htmlNice mod In next week i am changing injectors to 320cc@3bar black from BEX 190ps. TVUB/KVB/KRKTE already found. |

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?
