FFR818

I realize most members are in the US, and only see up to S6's, many have used later model jdm engines. I'm not sure if mine is S7 or S8, just that's it's one or the other based on the 16 bit ecu. I'm using AEM's infinity and just started tuning idle. Their base map has me running rich at idle, around 10.5 versus the requested 12.5. I have correction currently off. I was about to start adjusting it and it occurred to me that the s7/s8 models might have different size oem injectors. It's currently entered in as 550cc primaries and 850 secondaries. Does anyone know if that was changed on later model FD's?

I realize there are plenty of reasons the base map is way off, and while most I would think would make it lean, the lack of air pump and all other emissions are probably the root cause. I'm just covering my bases.
