Right control pressures for CIS ?
I have a WUR with bosch part number 0438 140 011, which I believe was used in older 924's.
Can anyone advise on the correct cold / warm control pressures for cars with this part (or for early 924's for the matter) ?? |

From the Haynes:
All models with CIS (K-Jetronic) Infection (1976-79) System pressure Test value 4.5 to 5.2 bars Adjusting value 4.7 to 4.9 bars 'Warm' control pressure 3.6 ± 0.2 bars (control pressure regulator fully actuated) 'Cold' control pressure 1.5 ± 0.2 bars at room temperature of 20°C (68°F) Injection valve opening pressure 2.5 to 3.6 bars CO setting 1976-78. except California 1.5 ± 0.5% 1976-78. California only maximum 0.7% measured ahead of the catalytic converter 1979. except California 0.5 to 1.0% 1979. California only 0.6 to 1.2% measured before catalytic converter with air pump and/or carbon canister disconnected and hoses plugged All models with Lambda injection (1980 and Turbo) System pressure (test value) 5.4 to 6.0 bar CO setting (at idle) 0.5to 1% by volume 'Warm' control pressure 3.65 ± 0.20 bars with engine stopped (no vacuum) 'Cold' control pressure 2.2 ± 0.20 bars at room temperature of 20°C (68°F) Injection valve opening pressure 2.7 to 3.8 bars Idling speed 900 ± 50 rpm Charge pressure controlled (full throttle enrichment) 2.9 ± 0.20 bars Leak test Minimum pressure after 60 min 1.0 bar Revisions for 1981-onward Leak test Minimum pressure after 10 minutes 2.0 bar Minimum pressure after 20 minutes 1.7 bar Fuel pump delivery rate 750 cc per 30 seconds 'Warm' control pressure 3.4 to 5.2 bar 'Cold' control pressure 2.2 ± 0.20 bar at 68°F (20°C) Injection vaive opening pressure 2.5 to 3.6 bar System pressure (test value) 4.5 to 5.2 bar
