	Can there be 3 FKSTT maps?? « on: November 21, 2011, 03:49:15 AM »

Hey!

Today I was scanning through my ME7.5 BIN file and found 3 possible FKSTT maps which is something unusual to me. 15928, 1594E, 15974 - all these locations point to possible FKSTT maps. Could someone please open my bin and check if this is even possible and if possible then which FKSTT map is responsible for cold start enrichment on which conditions?? Thanks

This is old post, but I hope you have enabled notify on reply

Did you ever find out why there is multiple FKSTT maps?
I can find four from my file, all with same axis but different values.
0x15AEA, 0x15B10, 0x15B36 and 0x15B5C
(FKSTT_0_A, FKSTT_1_A, FKSTT_2_A and new table on xdf file)

car is A4 BEX 140kw 8E0909518AH 0002 0261207941

And if someone knows where is KFFWL that would be nice.
Found something on new table 1, new table 2 new table 3 on that xdf file, but values are not logical.

Seems that KFFWL maps are at 0x18D8D and 0x18E1D

If someone has some information about the FKSTT maps that would be nice.
In 2.7T file there was only 2 maps witch were identical, in this file there is four and no two identical maps.
Does ECU only use one of the maps or does it switch maps at some cases?
Or are those maps even FKSTT maps at all?

This firmware (...518AH_ 0002) contain set of 4 KFFWL maps and set of 6 FKSTT maps.
Maps activation depends on current coding of ECU.
Possible coding variants are present on the picture.

OK. Thanks. Found all the maps.

Is there some logic behind that table that I cant figure out?
How can I tell witch maps are currently used?
Is there multiple KRKTE values also? That would make possible to change between RE85 and E98 with coding.

Also if you can confirm axis locations for KFFWL? Found 0x10128 and 0x10147 that may fit.

*edit* VCDS shows coding 0011711 and used FKSTT is one of the last three maps. Will continue testing when temperature falls closer to zero.
