subaru liberty RS TURBO ECU
 

Hey I've got a liberty early 90's and which came standard with the quadcam coilpack engine have swapped in later turbo engine. Trying to fit a liberty rs turbo ecu. It plugs straight in everything seems to be the same except the boost control wires etc. But makes the engine light flash and fans go on and off. It will crank and fire but seems way retarded or advanced ignition timing. Plug standard ecu in and starts straight up any helpers please that have done the swap??
