I was wondering what this unit

I was wondering what this unit does in the system? I know that 83' QVs don't have them but 84-85 QVs do. Is it mainly to work the 02 sensor or does it control pressures in the injection?

Rich,

it controls and/or re

Rich,

it controls and/or reads several things.

1- reads 02 sensor
2- reads TPS
3- controls fuel pressure via FV.
4- reads coolant temp sensor for control of FP, open/closed loop operation.


think that's about the majority of it's function.
