	my fuel not follow KFLBTS « on: June 03, 2018, 01:33:03 AM »

Hi all.
I use an BAM file with EGT disabled.
I set my TABGBTS to 400 degree.
This is my LAMFA stock from BAM file and this is my KFLBTS modfied by me.
I have a log too and i saw my fuel follow LAMFA between 4200 rpm even if i have EGT (calculate) bigger than 400 degree.

Any sugestion please!

After i changed tabgbts to 820 degree my fuel follow kflbts.....
The rule is not respected i think because i knew if egt > tabgbts ecu works after kflbts if egt <= tabgbts works after lamfa
Correct or i'm wrong?

In general the lowest lambda wins.

In order for BTS to be active (below lambda 1), and thus take over from lamfa, certain conditions have to be met.

What do you mean by "EGT disabled"?

Also, did you modfy the other BTS maps?

Thanks again NYET for your answer.
I have a k04-023 on my auq engine and i don't have egt on my ecu but i wrote a file from BAM (with egt), and i disabled egt from soft like this
CDATR (0x18196) = 0
CDATS (0x18197) = 0
CATR (0x192CA) = 0
So i think my car works now after egt model calculated.
I modified only LAMFA , KFLBTS and TABGBTS

Did you consult the rest of the BTS section of the s4wiki?

I wrote about bts between knock and other maps but I MUST READ more than 20 times to understand ok
If i read only one or two times all things are ambigous.

Have you configured CWLAMBTS correctly?

I know exactly how to fix it, but I see zero contribution to forum...
Besides, if you look at the BTS module, there's not that many variables. It is simple to compare to a car that has BTS enabled to find what you need to change.

I'm not sure thats really fair, he's clearly a noob :/ It isn't as if he's in a position to contribute anything yet anyway.
