Hi all,

I've been pretty absent from here for a little while, but I've been back at it - playing with my map again over the past couple of weeks. Some areas of my map are still based loosely around the original base map, albeit tweaked a bit now. However I've noticed that on a completely standard 8S map (97/98 UK Turbo 2000or EUDM GT) there is a noticeable 'blip' in the smoothness of the map for both fuelling and timing around the 4400 RPM, 24-30 load region. This seems strange to me, because there appears to a deliberate reduction of timing, whilst adding extra fuel, just in this small region.

Does anyone know why this might be in the standard map, and what it was intended to achieve? Something to do with emissions, perhaps? The TD04 should be fully spooled up by this point, so I can't see it being intended to help with spool. Also, this is mostly coming from the ignition base map, not the advance map.

I've not noticed any particular issues around this area on my map - it's more just a curiosity than anything.

Anyone got any ideas what the original Subaru engineers might have been trying to achieve by doing this?

4400 so roughly where your gonna land if you cane it to the limiter and smash into the next gear?
