I bought an ECU and was wondering if there was anything i should check for to make sure it will work alright? my car and motor arent ready yet, but i dont wanna be caught up in the end waiting on a new ecu becaus the one i got is no good. What can i check for visually in the ecu and outside? pics would be nice!
Thanks

 

put it ina nother car and make sure it runs

 

take it to honda and they can plug it up to their matrix and check its history...etc.
