Hello everyone,

Today I figured out that I will need to replace my ecu and the dealership no longer carries the ecu in stock.

I have been searching for a another ecu and I think I found the one I need. However, my question is, does production date matter when replacing the ecu.

I know it has to be the same spec as your car.
like transmission, year etc I wasn’t sure if production date matters to. Any insight to this would be much appreciated!

 

I'd suggest looking for another ECM with the same serial # as listed on the outside of the casing of the one you're replacing.

 

Ecu off of eBay

Ecu in car

is this what your are talking about

 

Exactly- your ECM model is MEC35-320C2.

 

Just a general question .. Nissan says my PN is 23710-CE805 which was updated to 23710-CE806.

Which is now discontinued. Is it fair to say that pn 23710-CE806 Is MEC35-320C2 ?

 

Correct- updated part #s can be updated and backdated. Almost all Z33 parts have been discontinued and you'll need to find them on fleabay or salvage yards.

 

Ok thank you for your time and knowledge.

much appreciated!!
