95 240sx ka2.4 ecu

[jlittrell87]

I am trying to find an ECU and I am having no luck. I have a number that was on the computer shell that says 3C in big letters also has A18-B92 G00 and has a stamp with 4613. What set of numbers do I use when getting the new computer? Does the 4 digit stamp need to match? I called napa and they gave me a totally different set of numbers I want to make sure its the right ECU before I order it

Why do you need an ECU anyway?
If you really do, you need to read out the ECU part number from the car with a scan tool while everything is connected. It will be a 5 - 5 part number just like everything else.
If this can't be done, dealer can come up with the correct number based on the VIN.
Sometimes a FACTORY reman ECU will have the part number on it.
That A18 number is a JECS leftovers and wont be of much use in finding another, unless you find a really sharp parts guy.
