I say B16A (P30/P08) chipped.
This way the chip can increase your rev cut which e-manage cannot do.
This include speed cut form standard ecu.
Fueling/timing all can be taken care by emanage.
What button function is this ?
I think from Evo 7 onward all model will have this button, but I really duno what function is that.
Anyone know and mind to share a bit ?
