Ok but tread carefully as what you are doing it is verry easy to make an error and mess things up.
the oft defs dont have the maf after start tables in the definitions for roms of any series C D ect.
but the romraider defs do
you need to know your original calid and the cald of your tuned rom structure
to be sure you need a hex editor and search your OFT rom for calid start characters ZA1J their will be three instances first 2 are your original calid third is the actuall calid and structure of rom. Some oft roms are calid hacked some are not, you need to work out what your dealing with. If all three are not same your dealing with a calid hacked rom.
This is a dangereous proceedure , understand what you are doing and be very careful and check your work else ecu will be bricked.
modifying calid or altering defs or using incorrect defs can very easily lead to a bricked ecu.
four guys i know of have bricked ecu doing one of the things above
it can be done but check and re check your work.
once you know what the real structure of the oft rom is say is a B01D then you can grab the B01D romraider def and then change the internal calid to what your original calid is example A01D but you must be sure of both your original calid and what the real structure of the OFT rom is , if in doubt give it a miss as their is no second chance. You will then be able to open your oft rom with your hacked definition that contains the maf after start tables.
alternativly you can do what the other guys did and copy the xml code into your oft def but you stil need to copy this code from the correct romraider def for the structure of your oft rom whick may be different from the file name. you cannot use their examples or xml code as they are on different roms, every rom is dofferent B01C tables sre not in same location as B01D.
again it dangereous territory and mistakes will brick your ecu and no one wants to see that
merry christmas
