Most of the Early Nissan EFI systems are pretty similar and mine runs with the bare minimum of connections hooked up so I guess I would try that to begin with, it should only need the -ve coil pulse, a constant 12v and a switched 12v to work (plus an earth of course). I would try checking that the throttle position sensor wasn't damaged during the swap, because mine only worked intermittently at the start and it just went haywire sometimes, nearly stalling then idling at 2000rpm etc until Errol sent me another one to fix it. Like Terry said, it sounds like it's engaged 'limp-home-mode' for some reason (usually a sensor fault- I've had this too with the water temp sensor plug which I broke :) which for my ECU means it runs insanely rich mixtures but maybe yours just wont go over a certain injector duty cycle?
Not much but I hope this helps.. - Tom [EMAIL PROTECTED] wrote: >Is anyone familiar with the EFI from a 280ZX?
