subaru ecu/ems, subaru engine electronics Options

[ModPR3]

subie guys need your help again. after finding out that a 911 engine rebuild cost over 8k the subie or v8 path is looking good again. if i ran the 2002-2004 wrx 2.0 turbo motor what do i do about the engine control unit or engine management. can the engine be run with the stock subaru ecu or does it have to be switched out to a standalone unit. if the stock ecu can be used, how hard is it to wire into the 914. thanks.

thanks for the info, im gaining knowledge left and right. if im running a turbo on a subaru or a type 4 engine with FI, and im running at 8 pounds of boost at 4k rpm but then i turn down the wastegate and now im at 12 pounds of boost a 4k rpm will the ecu adjust for this difference and at that time is it in closed loop so thats why it adjusted.
