Sooo, I am searching, looking around for the information I'll be needing in order to plug-in and use the '88n/a 5 speed federal ecu on the '87T(5speed federal) build I am doing.
*I am not having very good luck locating the ecu pin outs and descriptions for the various years(84-89) and models(n/a, turbo, calif, federal).
**Once upon a time, I had saved off from z31.com, information that showed the ecu pins and functions for various years...it is currently lost.(If I locate it, I'll upload it to this thread)
***Has this information been covered, and I'm just missing it?
thanx,
Dan

Notes:
1 most control voltages seem to be negative such as fuel pump, injectors and the Ignition coil. Because of this, a good ground is important!
2 The injector wiring difference between T’s and NA’s might be a contributing cause to hesitation’s after the injector campaign. There is not much of a difference between the T and NA’s wiring, most notably the difference in wiring of the FICD and AAC valve on the T’s and FICD and Idle-up solenoid on the NA’s.
3 not many differences between the 84 and 86, notably the lack of the fuel pressure regulator control module (pin #115). Also noted are the lack of the headlight switch (pin #22) which probably effects the idle speed and the addition of the AIV (air injection valve) on the 86 models.
