Graph for measuring voltage in situ. Bosch licensed the concept to many automobile manufacturers. There are several variations of the technology offering technological development and refinement. Be prepared that some bolts will require torx bit hammered in to get them unbolted, because 6 mm hexagon bit will turn around This ensured that when I tightened the mounting screws the tower would be perfectly aligned for future adjustment.


Instead of injecting fuel into the intake, this injector allows fuel to bypass the fuel distributor, which varies the fuel pressure supplied to the mechanical injection components based on several inputs engine speed, air pressure, coolant temperature, throttle position, lambda etc.

Because this adjustment seems to be VERY precise and i don’t have the tools that are needed for tuning of this EHA, beside the fact that it is impossible to do once it is fitted in an 8.

If existing one is acceptable, put it on, turn the engine on, get the necessary jetrinic speed and turn potentiometer until 0,67v jetrlnic reached. They have advised to get a replacement throttle body. Although conceptually similar to most later systems with individual electrically controlled injectors per cylinder, and pulse-width modulated fuel delivery, the fuel pressure was not modulated by manifold pressure, and the injectors were fired only once per 2 revolutions on the engine with half of the injectors being fired each revolution.
