MERLINS RALLIART & EVOLUTION-X TUNING GUIDEThere are a strict set of format rules for definition files to work properly, so the bestapproach is to copy a section containing a similar function, paste it into the file,then edit it to the new parameters. Note that the datum ‘level=x’ refers to the userlevel, where Level1=Developer, Level2=Advanced, Level3=Intermediate. No levelcommand allows access to all user levels. There is a good xml description, withrules, in Wikipedia.Below is a stripped down section of definition file for a JDM Evo7, showing theessential elements for a valid definition file. For EcuFLASH to read your ROM thexmlid, the internalidhex and the four data bytes at address F52 have to match.Note that EcuFLASH likes hex data in lower case. Hex editors are usually caseinsensitive.98640014f5298640014MitsubishiJDMLancerEvo 7Manual2002mitsukernelSH7052REV: 0.K merlin@three.com.au Page 14 of 134
MERLINS RALLIART & EVOLUTION-X TUNING GUIDEFollowing after all the romid stuff is the scaling data. These describe the size andformat of the units being used. The scaling expression needs to be read byEcuFLASH before the function that references the scaling.Then come all the parameters, tables and maps. All the essential elements to makea valid definition are shown, the name, category, the binary address, type, andscaling used. Then follows the scaling used on the two axis, in this case Load andRPM, with the relevant address and element size and the scaling.The bit at the end is required to close the file correctly.Note 1:toexpr="x/10" is a sample formula which converts the raw ROM data from hex to adecimal value, then applies the formula for conversion to suitable scaling units fordisplay on the EcuFLASH window.Note 2:frexpr="x*10" is the corresponding reciprocal formula to convert data entered in anEcuFLASH window back into the ROM which the ECU will understand.Note 3:format="%.1f" will give displayed values to 1 decimal place. %.0f will have nodecimal places and will round off the displayed value.Note 4:storagetype="uint8" means a one byte data variable (8 bits).storagetype="uint16" means a two byte data variable (16 bits).REV: 0.K merlin@three.com.au Page 15 of 134
