R33 Ecu, No Diagnostic Port\screw

[benny bobo]

hey,

my ecu (r33 gtst s2) does not have the diagnostic port or screw (whatever it is)... it just has a hole... is this normal for s2 33's? It WOULD be the stock ecu wouldn't it?

Not necessarily, heaps of imports have a/market ecu's installed. Would need a photo to tell

I know on some RB(30)e motors with the later ecu that they have a similar hole that looks like theres nothing in there, but the screw is actually right down inside rather than sticking out near surface.

Have heard of internals being switched over to keep factory ecu box to look stock for rwc also
