GM Chevrolet Cosworth Vega E.F.I. - ein D-Jetronic-Fahrzeug

With the vacuum compensation and higher fuel pressures, it seems that the Cosworth EFIhas some of the characteristics of the L-Jetronic system. The Djetronic system, many of us have, were designed to run at 2bar (~29psig) and had no vacuum compensation on fuel pressure regulator. Several other differences too.

Found this pdf that describes the Vega EFI:

Hi Graham,

well you have to be careful. It is not a Bosch D-Jetronic system, it only uses some of its components including MAP sensor, yellow injectors, throttle switch and as it looks fuel pump. But the fuel pressure regulator and héspecialyy the ECU are different. ECU is even developed by Bendix and has nothing to with Bosch. But remember that Bendix was the one that originally developed electrojector which is the father of Bosch D-Jetronic.
