Hi everyone
I have Problem with KFLBTS / Lamfa run too rich at high rpm on 06A906032HJ on stock hardware turbo injectors etc only mods are TIP + decat albo sai/ vvt/ o2 post cat is disabled.
I set TABGBTS to 800 . Lamfa and KFLBTS are set like in screen shoots
after ca 5000rpm am running very rich req 0.73-0.78 lambda however EGT calc in 34 block didn't passed 800C so it souldn't trigger KFLBTS ?
Where i've made mistake ?

You need to log what the the output of LAMFA and KFLBTS etc is to see what function is richening things up.

Something triggers it.
Cat & SAI are removed correctly?
Any DTCs?
More logs will throw some light.

Rick- taks for any thoughts
Professor - yes i have four dtc
no communication with air bag / cluster/ abs + relay 271 ( i have 1.8T AQA dbw it is AJQ/ATC + changed wideband ECU + WidebandO2+ maf ) but on 125 block there is normal communication with ABS - it works good only dtc appers Could it trigger me7 selffail mode ?
I make log - use me7l if i am good thinking
Kflbts hits after 5700rpm when tabgbts_w {EGTForPartProtection} is passing 920C so i think it simply trigers FBSTABGm which is now set stock on 920C and after higher value to enrich fuel..
also after 5700rpm tabgm EGTModelBeforeCat is only 740C so i don't know how to set properly the TABGTS and FBSTABGm ?
Rick and Professor - What should I do now ? Should I worry about tabgts_w ? 920C is quite high temp i think ? It is reliable ?

I don't see anything obviously wrong here. It's pretty much doing exactly what you are telling it to do.

As nyet says only it goes 0.75 instant after 5750rpm. This 0.75 is legendary  |

Nyet - nice graph !
Professor- jest 0.75 it is legeNdary but how to set AFR properly without risk of to much temp /engine damage?
i set tabgts to 800C because most people set like this
no one told that tabgts_w go so fast and high - to 940C on nearly stock car and triggers FBSTABGm.
everyone said that egt on 034 block is calc EGT model and is used to trigger KFLBTS and i saw 780C max on mine so set it to 800C
but as i see calc EGT on 034 block is useless kflbts is triggered by 'other' EGT model.
What would you do now ?

Something triggers components protection.
Perhaps boost/torque maps are not quite good modified, since fueling as you say its stock.

I say that turbo/injectors/are stock but fueling is tuned - lamfa and kflbts as set like in first screenshoot lamfa 0.836 from 3000 to 0.8126 to redline. kflbts map are little leaner than stock 180hp map. tabgts set to 800 FBSTABGm stock. Could you download au.bin and look into ? def is here http://nefariousmotorsports.com/forum/index.php?topic=401.0 |

I mean car is almost stock  file isn't stock. Attach ori file and modyfied file + screenshot what i have changed in modified file in compare to stock file. What is making tabgbts_w to calculate EGTForPartProtection so high ? could it be bad scaling load axis in kflbts map ? Where I've made mistake ? |

Lamfa: 1CEAC use this (told you one byte difference).
FKLDOBG_1_A, VWPMBBR, NWPMBBR : Why changed these?
After 5750rpm component protection is activated since it follows your BTS table. Something triggers it.
All these lambda bank 1 you zeroed are necessary for your setup?
SAI is totally removed from your car?
Other DTCs that the ones you ve mentioned already?
