928 618 123 LH ECU/Brain Repair - USA Agent for UK based JDSPORSCHE - 87 to 95

928sRus is Proud to be the USA Agent for JDSPorsche. JDS has for many years been the leading repair facility for the 928 LH2.3 Jetronic ECU/Brain.
The Bosch LH 2.3 ECU Circuit Board from August 1986 (Porsche 1987 model year) with the introduction of the S4 model, all 928 models used the Bosch LH 2.3 Jetronic fuel injection ECU (sometimes called the “Brain”).
These ECUs have a poor reliability history. This is almost entirely due to failure of the “tile” – a Thick Film hybrid circuit exclusive to Bosch. JDSPorsche has developed a re-engineered replacement for this vital component.
A common LH ECU failure is for the fuel pump to fail to run due to the fuel pump relay not being energized by the LH ECU. Often, a regular clicking will be heard in the engine bay as soon as the ignition is switched on.
We are now able to offer re-manufactured LH ECUs to Porsche 928 Owners. Due to the large number of variants of the basic unit, it is often not possible to offer an exchange unit from stock. Your faulty unit can usually be turned around by our workshop in one working day.
