hi i have 96 wrx with v5 ecu thinking of changing to a u8 with a scooby ecu installed . however does the scooby ecu completly replace the map of the u8 as the u8 is from the earlier lesser powered wrx. and so obviously i want the scooby ecu to be the only map any ideas ? thanks rob

 

Correct, the ScoobyECU will over-run the original map, ie. it will run the ScoobyECU map.
