Hello,

Need help about ECU & BCU
my car is infiniti G35 coupe M/T 6 _ 2004_07months
i have lost ECU & BCU,
found both from infiniti G35 coupe M/T 6 _ 2004_12months (revup) ECU, Engine whires & BCU
what problems i should expect from this swap ? ?

Please elaborate on what you mean by "lost ecu & bcu".

You shouldhnt have to swap out all of that if the problem is as simple as your ECU is bad. If your factory ECU is not working you can easily find a replacement on car-part.com and have the key reprogrammed. There is no read to replace the BCU....its only function is to match the key to the ECU.
