    We are having some real issues. Have finally got good set-up instructions for the unusual KE-Jetronic (Swiss '89 328), but now the ECU seems to be sending requests that appear randomly to be changing the car from running with an appropriate mixture to running rich. Since we don't have a wiring diagram for this ECU, we can't determine whether there is a sensor or some other component that is causing the problem. Any help would be MUCH appreciated.

    Ferrari published a supplement in 1989 describing the operation of KE3-JETRONIC for the 328 and 3.2 Mondial (Cat. 549/89). I found mine on ebay several years back. I think it has everything you're looking for.[​IMG][​IMG][​IMG][​IMG][​IMG]

    I have had a starting problem for some time after the car has always had excellent engine behavior. The injection quantity is clearly too low.
    A digital copy of the Manuel (corresponds to my vehicle type, KEIII Jetronic) could help me.
    Many thanks.
