ecu spec needed ...tech heads help
can anyone tell me some details on my ecu for a jdm spec my00 wagon... on the label it states
A8
2261 AE491
i presume 491 is the model code but what pressure boost does this have? fuel cut etc? ive read somewhere that a wagon should only boost at around 0.8 bar max but mine goes to 1 bar so id like to know its spec....it has had a replacement ecu previously as it had fuelling problems and wouldnt pass the mot,subaru uk had to order this ecu from japan and i was told it was the correcty one for the car.... anyone shed some light on this particular ecu?

Mapped boost is 0.739 bar to 5400 rpm dropping to .675 at 6200 rpm and .611 from 6600 rpm. Fuel cut due to boost is set to trip at 1.005 bar, maybe your gauge is in error.
