does someone know how the ldrmax axis should look like?!

I`ve managed to find factors and offsets for turbo maps:

12B94 KFLDIMX
8x16 map, 16 bits LoHi
Factor: 0.005000
Offset: 0
Precision: 3
Y 0.250000 0 0 109D4
X 0.039063 0 4 1A82C (I`m not sure about this one, as max value is 1250.xxxx on other maps from 1.8 that i`ve seen max is 1100.014x)
Values are %, X is boost pressure & Y is rpm. Am I right?
As i know, this map limits some way overboost.

12C94 KFLDRL (Boost linearisation)
10x16 map, 16 bits HiLo (Wierd, as i`ve know, most maps on VAG are LoHi)
Factor: 0.005000
Offset: 0
Precision: 4
Y 0.250000 0 0 109D4
X 0.005000 0 4 12C94 (not sure about this)

Note, axis was write as:

Found FKKVS map and looked below for KRKTE, but i just can`t find it.
Can anyone give me a tip where to find this one?

Thank you.

Am I right if i say that KRKTE is at 0x1B0FD ?
Value is 160, with factor 0.000111 means 0.01776

nice ecu to spend some time in front of your desk ;) . Do it in boot mode...avoid obd flashing. But first make a good file. :thumbup:

I already have a desk setup and a replacement ecu (with other code, from A4 AWT engine, but tested and work fine in case my ecu will fail).
I`ve made some research on more than 10 versions of 1.8T (150, 180, 225bhp) and seems that maps are in same order

Code: Select all: KFKHFM KFZWOP KFZWOP2 KFZWMS KFZW KFZW2 KFZW_UM MLHFM MLOFS - Single value KFMIRL TEMIN - Single value KFZWMN LDIATA KVB - Single value KFMLDMN KFMLDMX FKKVS KRKTE - Single value LAMFA KFLDIMX KFLDRL LDRXN LDRXNZK KFDZWOB

I can pay someone to make me all modifications, but i really want to learn everything`s possible about this ECU to take best of it.

Just wantd to see differenced from my file and a 225bhp 512K file, and looks very wierd. There are 2 identical KFZWOP or KFZWOP is identical with KFZWOP2?
