Re: 2tg EFI wiring

From what I remember from my 3TGTEU...
OK from the Circuit B+ or Bee Plus as it is known is the switched 12 volt rail from the main relay. The socket marked with B+ E1 and Vf, I think is a diagnostic socket as it does not plug into anything. Unless it is the dashboard.
Where is the socket exactly? if I can find my old compuetrs and I havent thrown them out I will check for you but I think I tipped them years ago..
There is obviously some control exercised from the ECU chip. V possibly is Volts lower case f unknown, forward voltage, frequency? so many variations in electronics are possible only the manufacture would know. Suggest you check through other wiring diagrammes and eventually you may find a reference that is not abbreviated. An 2TGGEU handbook would work but cant help there. Why not ask one of the Jap shops in Australia who import 3TGTEU engines??
I doubt if it will stop the engine running as I used a 2TGEU computer to start and run and act as a get home computer for my 3TGTEU in 1984 long before any of this wiring information was released to the general public.
The computers are pretty basic, spark, injector pulse and and bit of engine management. Your EFI anti pollution computer uses some basic inputs from the O2 sensor in the exhaust manifold, throttle position etc and can be discarded. I never used it on the 3TGTEU engine. Dont forget also there is a speed limiter or cutout somewhere in the dashboard wiring to limit domestic models to 180 kph. Shaun Maloney can assist his number is elsewhere on these pages.
You know what the japs are doing to Nissan 280ZX EFI?? Chucking em out and fitting triple weber carbies. There is a message in there somewhere..
