Anyone know the correct range for the frequency valve dwell angle??? The Bentley manual sez 41-43 degree midpoint. The Volvo greenbook (http://www.k-jet.org/files/greenbooks/TP11585-2_oxygen_sensor_fault_tracing.pdf) says range should be 49-59 degrees.

I would guess the Volvo manual is correct, but wouldn't put much of a bet on it. It does mention the 54 degree "fail mode" value. Mine goes to 54 deg when the O2 sensor unplugged, which is normal according to the greenbook.

I have an 1982 245DL B21F-9, automatic. Has C/V ignition and k-jet FI.
