Hello?
I'm starting remap my TT180 with LAMFA Map but my definition file seems strange.
X-Axis values are (0, 160.3648, 40.0789, 120.6730, 88.6575, 0.3815)
So I've changed Axis Values 16Bit(LoHi) to 16Bit(HiLo). (0, 50.6296, 59.5354, 90.3209, 94.8836, 97.6640)
I don't know 16Bit(HiLo) is right. and I'm not sure LAMFA,Axis address are fine...
My X Axis is right?
Please check attached files and give me your opinion.
Thanks!

Where did you get the definition file from?

This is correct layout:
Map Name:Lambda Fahrerwunsch
Map ID:LAMFA
Start Address: 1C98A
Cols/Rows: 6x15
Values: 8 Bit Unsigned
Factor: 0.0078125
Offset: 0
Unit: Lambda
X Axis:
Start Address:1C97E
Values: 16Bit LH Unsigned
Factor: 0.003051757813
Offset: 0
Unit: %
Y Axis:
Start Address:1C96E
Values: 8Bit Unsigned
Factor: 40.0

Thank you for information MarkS4.
I appling your correction to my project file.
I have one more question.
In the S4 wiki, "LAMFA torque axis is restricted to 0.5%~1.0%"
But my torque axis(I attached img) described (50 60 89.99 95.00 98.00 100).
Why these are different? Can I believe the correction LAMFA(I attached img) is right?
S4wiki
LAMFA - requested lambda. Not very flexible for high load enrichment, uses requested torque instead of actual torque. Also, the stock LAMFA torque axis is (incorrectly) restricted to 0.5%-1.0% on 2.7t ECUs. You will have to change it to full range (multiply each value by 100 to result in 50%-100%) to use LAMFA, otherwise, the 1% column will be used at ALL requested torque points![16]
Thank you !

You're not tuning a 2.7.  Your axis is correct. |

2.7 Ecu has incorrect values for axis from factory, because the map is all values of 1.00, it doesn't matter.
When you want to use the map, we would change the axis values to give proper resolution across the range (ME7.1 Only).
Use the values I gave you and you will be fine.

Hello sonique? You mean my original data with changed Axis Values 16Bit(LoHi) to 16Bit(HiLo). (0, 50.6296, 59.5354, 90.3209, 94.8836, 97.6640) is right? You said "0" means idle data. according to your opinion idle Lamda is little rich (under 1). Is this right? thank you |

In map properties, set it from Two-dimension to 2D Inverse. |
