07 USDM WRX MT: VF39 with 3port BCS, 93oct (A8DK100X)

First and foremost this is a modified version of Airboy's VF39 map.

Mods:
07 WRX
Grimmspeed 3 port BCS
VF39
Sti TMIC
3in catted dp tapering to a 2.5in axleback
stock intake (with gpmoto elbow instead of snorkus)
93 oct (Shell V-Power)

Relevant changes from Airboy's Map:
Reduced WGDC
Adjusted Turbo Dynamics
Rescaled MAF back to stock parameters
Lowered boost because I wanted it a bit "safer"
I think I changed a few other things but those were the major ones...

Driving impressions from me and the few passengers so far:
1. The accel is very very smooth
2. Pulls all day in comparision to the TD04 (need to get used to shifting a bit later)

If you have any questions/comments I visit this forum fairly regularly but I'm on Nasioc more. Also I am still working on this map and if any of the gurus on here have any suggestions I will be more than happy to test them out.... enjoy

Enjoy

You can probably run about 1-2 more PSI of boost in the midrange safely, if you're looking for more torque.

I'd also suggest more AVCS advance in the same area

.

Other then those minor suggestions, it looks like a well designed map!

I think I may up the boost a bit. I want to play with the WGDC a bit, I suppose I'll look AVCS aswell as see if I need to do any MAF adjustments (but that will be just for my personal map, unless somebody really wants to take a look at it). Wont do any adjustments until this weekend.

would this map work with a GMBCS?

Probably. In my experience with the GSBCS, it typically runs just slightly lower WGDC then the GMBCS. As a result, you could probably run this map fine, although you may need to raise WGDC slightly, depending on how your car is hitting boost.

any changes to timing?

flashed the map today, accell is super smooth. I would up the boost a little more or add some timing for added torque. the top end seems a bit weak, for me at least. Im running a vf34 with turbo xs up-pipe and full catless dp and sti cams. I was hoping for a little quicker spool but overall its a good map. I have no idea how to tune avcs at all and I would think that is where more power could be squeezed out for the top-end.

Glad you like it... I actually have a new version:
Changes from R2 to R4 (R3 was a bust...)

slightly more boost
adjusted avcs (more aggresive during boost and got rid of the built in "EGR")
tweaked WGDC

So if you want to take a look it here it is...

Hey could you post a 3rd gear log of this rom? I am curious how much power this rom puts down in airboys spreadsheet compared to the xpt stg 3 race rom.

I see the log at the top but I am requesting a log of the latest revision.
