NO! The california ecu is NOT exchangable with the federal!!!! Your Cal
model has an O2 sensor and federal models don't. You also have electronic
ignition system with NO points in your distributor! Your timing is also
different.

Subject: ECU for CA

Going through the steps using the Bently manual I must of accidently cross
two connectors on the double relay using my multi meter shorting the ECU.
Apparently this effected the fuel pump relay circuitry which the ECU would
complete ground. Question can this ECU be repaired by identifying the faulty
electronic component and replace it? I also purchased a used but good
computer but the numbers are different. My 82 Westy is a California emission
vehicle and most part numbers are different from the other 49 states. The
original ECU number is 071-906-021B (California model) and the one I
replaced it with was a federal model 039-906-021D. The Van is running OK but
I notice an increase in fuel consumption aprox 1.5-2 mpg. Will the Van pass
emissions next time around and  will it cause problems to the engine? One
last question does the computer electronically advance the distributor
timing? The reason why I ask is when I accelerate the engine and use a
timing light the timing mark goes all the way to 40 degs. BTC the Bently
manual says different. Please provide some helpful feedback?
