Today I got my bluebird from soko, I wasnt supposed to get an ECU but there was one on it. Its smaller then the normal sr20ecu so im thinking maybe its a 1.6ecu? here are the numbers on it.
31036 79E00
A64-000 E16 0327


TIA,

Nate

my 97 GA16DE (1.6L) has the following:
JA18G89 BL3 6Y15

you might try calling JWT, they know most of the jacs or jaxs #'s (spelling?) on the nissan ecus.

I think I will probably do that, thanks
