ECU Identification

[Ezzie]

Does anybody have a list of the different ECU's used on Skylines?

I am trying to identify one here, it has an "F8" on it and Nissan P/N 23710-0W715. What was this from? It currently is with an RB26DETT motor/tranny set I am looking to purchase but I need to know if it from an R32 or R33?

Someone told me that the R32 ECU's are easier to reprogram, is this true?? How?

Any help you can provide would be most appreciated as there is not a lot of info in North America on this subject (yet).

This site lists some ECU PN's:

but it shows that the R32 GTR used an ECU with PN 23710-05U60, although later in the list it shows R32 GTR ECU with PN 23710-05U02.....but I'm wondering if that is a misprint because it is listed at the end of the R33 'group'. Anyway, your -OW715 ECU isn't anywhere in that list so may not help.

Anyone else have any suggestions???

Found my answer through a Nissan parts guy. The R32 GT-R used the following ECU's, identified by part number.

"The R32 with a RB26DETT engine appears to use a 23710-05U60 from 8/91 to 4/92, 23710-05U61 from 4/92 to 2/93 and 23710-05U62 from 2/93 on."

Hope that helps somebody else. Watch out for some of these engine importers, I just had a guy try and give me something else stating that it was the correct ECU, turned out to be for a completely different engine (VG33).
