Today I discovered my ek4 (b16a2) is for some reason running a p73-003 ecu from a b18c, which would possibly explain the late vtec engagement point and bad fuel consumption. From what I understand the stock and proper ecu for b16a2 is p30? I can't find this ecu for sale anywhere, I have a spoon pw0 and stock pw0 ecu from ef9 (jdm b16a), can I use these at all or will it not work with the b16a2 distributor? Does anyone know where I can buy a p30 ecu or what other options do I have?
Thanks
