The design of the 13CU also deviated from the original L-Jetronic design in that it used a hot-wire air mass sensor rather than the Jetronic's mechanical flap sensor. The 13CU was further developed into the 14CU, which had (among other changes) an ECU that was more physically compact. The 14CU was used in US-market Range Rovers in 1989. Both ...
The ECU was much cheaper to produce due to more modern components, and was more standardised than the L-Jetronic ECUs. As per L-Jetronic, a vane-type airflow sensor is used. [4] Compared with L-Jetronic, the fuel injectors used by LE-Jetronic have a higher impedance. [5] Three variants of LE-Jetronic exist: LE1, the initial version.
A Digifant II DF-1 Engine Control Unit used in '91 Volkswagen Golf Cabriolet with 2E engine. Digifant is an Engine Management System operated by an Engine Control Unit that actuates outputs, such as fuel injection and ignition systems, using information derived from sensor inputs, such as engine speed, exhaust oxygen and intake air flow.

Mid 1980s JECS LH-Jetronic ECU. 40 pin IC bottom left is Hitachi Motorola 6800 clone, 28 pin IC (socketed) immediately right is 16kB ROM containing maps. JECS logo bottom left. Bosch first produced the Jetronic EFI system in 1967. K-Jetronic & L-Jetronic followed from around 1973 [6] which is when Nissan became involved.
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH (commonly known as Bosch) which combined control of fuel injection and ignition in a single unit. By controlling both major systems in a single unit, many aspects of the engine's characteristics (such as power, fuel economy, drivability ...
Bosch developed their D-Jetronic (D for Druckfühlergesteuert, German for "pressure-sensor-controlled"), from the Electrojector, which was first used on the VW 1600TL/E in 1967. This was a speed/density system, using engine speed and intake manifold air density to calculate "air mass" flow rate and thus fuel requirements.
It was the Robert Bosch company which was the pioneer of the first electronic CD ignitions. (Bosch is also responsible for the invention of the high-tension magneto.) During World War Two, Bosch had fitted thyratron (tube type) CD ignitions to some piston engined fighter aircraft. With a CD ignition, an aeroplane engine did not need a warm up ...
