Hey i know that at least on the later hitachi carbed EA81's there were dual duty solenoids mounted on the intake manifold but on the carter-weber carb there was only one mounted on the carb itself. I swapped intakes and my car runs great with the two barrel but i dont have a duty solenoid cause i would only need one. So my ECS light comes on because of this.

 

Anyone know if there was a year when there was only one duty solenoid mounted on the intake and if so...anyone got a good one they want to get rid of Thanks alot guys.

Hitachi and Carter/Weber feedback systems are not compatible. The ECU is different among other things. Just rip it all off and use a non-feedback carb. Sounds like maybe you did already?

 

Pull the ECU out - it's under the drivers side kick panel. That will extinguish your ECS light.... forever.
