In your "Catalyst heating - fuel correction % - additional"

Code:

-<table name="Catalyst Heating - Fuel Correction % - Additional" storageaddress="0x16B6">

<table type="X Axis" storageaddress="0x1449"/>

<table type="Y Axis" storageaddress="0x1440"/>

The X Axis storage address should be 0x144A, checked in the hexdump (X is at 1448 in 16bit, and first descriptor is 00008 for the number of values) Makes the X-Axis a better looking 0 20 40 100 600 1200 2200 6600

my fault too. byte counter for word data.

Code:

CAL:1448                 db    8
CAL:1449                 dw      0, 1400h, 2800h, 6400h, 5800h,0B002h, 9804h,0C808h

thanks. fixed to:

Code:

CAL:1448                 dw 8
CAL:144A                 dw      0,   14h,   28h,   64h,  258h,  4B0h,  898h, 19C8h

You will need to populate the <ecuid> element in the <romid> section for all defined ROMs to be able to use this feature.
