anyone know if 96r ecu will works on 99 max

 

I remember reading like a year ago that a 1998 maxima owner switching out his ECU for the 1995 maxima ECU so he could get the Jim Wolf Technology chip...and the swap out went fine...I don't think there would be any problems. The only thing that is different is the 1996 has less sensors like in the exhaust and might have less safety features...therefore it might not match up exactly...but if you don't mind those features not working in your car than you shouldn't have any problems.

 

Short answer: no.

Long answer, defnitely no.
