I'm actually wondering about some ROM code adds, like the "GrN" specials...
But I don't have any of those ROMs.

The ones I'm looking for are the 2 following :
4SLED910 (JDM STi 7, AF481)
A4TE000n (JDM STi 03 TS GrN).

I am also wondering about the 400grs MAF tables listed in some ECUs, like the A4TE002c and A4TE002q ROMs...
Is this a Denso add to previous ROMs or a third party code modification (by an UK based company) ?

Well... any input appreciated

I have them in my rom (ah581), there are several posted in the twinscroll section below, and the jdm sti section as well.

I don't know what the GroupN parameters are actually for.

Have a look at my AF481 rom in the JDM STI 2001-2003 section, it is full of Group N changes. Car is STI 7, 2001. I would be interested to know what they all are and if they are used, what for, what do they replace etc.

ECU is A4SD900B, AF481-9546.

Thanks mates

Mmmm, so different ROMs share these GrN parameters... I didn't knew AF481 serie's like the A4SD900B had similar inputs.
Same for AH581 serie's...

I'm going to have a look at these right now and let you know what are my findings.
I want to figure out what are the changes and what they're made for.

Anyway, If anybody has the specific Denso ROMs I mentionned, please let me know : their Denso refs are one step forward, I mean they look more specifically dedicated to GrN applications...

Tks

Just forgot to mention the 400grs MAFs...

I'm expecting this to be an "overall" factor applied to the std 300grs scaling in the code, so that there is no need to alter any load axis in any 3D map...

Any thoughts or experience ?

He m8 ? some news ?
