Hey guys , new here ... Long story short . Car is A3 AJQ 180ps , i've attached the my ols . So here come the questions , i've been thinking using lamfa + kflbts for further enrichment , then i realized that i don't have EGT so BTS went down the pipe . So i am only left with Lamfa now ? If so ok i can deal with it , but then i looked at lamfa , and boy do those numbers seem wierd - but car is running fine without problems . With the reading i've been doing i understood that the lowest req lambda is top priority , so that got me thinking that there must be some other map aswell ... ?  So am i missing something or are there aliens in my car Cheesy

to my(limited) understanding is that you dont need an actual egt sensor to use BTS, the ecu uses a calculated value.

as for LAMFA, you just need to rescale the axis for better resolution.

Are you sure that's an original file?

No i grabbed it from ecuconnections (06A906032R  , the one from the car was locked with noread( i have it here with me) - and even after removing the noread tag still cant open it. Anyways i was planning to start from scratch so i went ahead and downloaded it. Found the maps and WOW Smiley If u are asking i can assume the address is right ... Another thing i noticed , tabgbts is set to -45 and kflbts is even weirder .. I start to think that i messed something up at somepoint .. Cheesy

I think ME7 uses KFLAMKR as richest AFR. So you have 1 (14.7) even if Lamfa = 1.9

Ok , will have to find KFLAMKR then . My concerns are that this might not be the ori. Has anyone ever seen something like this ? Also even if the car doesn't have egt , now that i see tabgbts at -45 , does that mean that if kflbts is richer then like u said kflamkr , it will run on it ?

1.8t has no EGT sensor, but it uses Wideband O2, so be sure BTS works  Wink

Sorry, your 29F400BB uses Narrow band sensor. My mistake.

this lambda map is correct...remenber, if you didn´t have lower lambda factors than 1,0 it will stay in closed loop (thats that 1,9XX values in LAMFA).

EGT is allways calculated in 1.8T engines, even S3 that have an EGT sensor does use mathematical calculation for protection (didn´t check in FR, but is what you see when you tune it)

in 1.8T you you have 29F400 normally it is narrowband and have only ASR control, if has 29F800 than normally it is wideband and has ESP+ASR

So even if it does have EGT sensor it calculates the current egt rather than just see what the sensor says ? And i can use bts with the current value -49(that means always activated ) ?
