It's the opposite. 100% WGDC means the gate stays completely closed. 0% means the gate stays open.

Any way to change the dimensions of the TPS Correction map (i.e. instead of only having 6 or 7 points of adjustment, adding a few for better resolution)?

Better resolution for smoother WGDC transition.

Second post has been updated to include instructions for JDM Evo 8 96260009 ROMs. It will not work with 96260007 ROMs.

quick question, maybe Im gettin greedy, and Im not opposed to tuning load based boost: 885807XX, AUDM IX v7 rom, no map sensor present in rom, but I do have a 4 bar in my USDM car, is it a complicated implication/impossible mission, or has it just been unrequested etc. AFAIK, there may have been some EDM roms that dont come with MAP sensors that had this implimented. JW..

Its no more difficult for me to work out than the others. Takes about 3-4 hours of my time.

Thanks mrfred!

I've updated the xml for 96260009 on code.google.com/p/ecurom to include the correct direct boost tables.

Im pretty sure I have checked every thing and I cannot get my ecu to make corrections to the WGDC. In evo scan this just reads zero in the WGDC corrections all the time, and I have all the values filled in, (stock values, stock solenoid). Also, the max upward correction table is scrambled

Is this a sign of any thing obviously wrong with my v7 rom.

The v7 ROM that you downloaded has an omission in the definition which results in the max upward WGDC correction table not displaying properly. Right click on the table on click "edit map". Make sure everything in there looks like this:
