Rare ECU Heritage Archive
Allcar Electronics preserves and supplies electronic control units from the 1970s onwards. We hold rare Lucas, Bosch Motronic and dealer-only units that are difficult or impossible to source elsewhere — supporting classic vehicle owners, restorers and museums across the UK.
A timeline of automotive electronics
Early Bosch L-Jetronic, Lucas analogue ignition, mechanical-meets-electronic injection systems.
Lucas 4CU / 14CUX, Bosch Motronic ML4.1, Renix and early Magneti Marelli — the first true engine ECUs.
EDC15, Motronic ME5/ME7, Siemens MS41 — the start of OBD-II and immobiliser-protected platforms.
EDC16, ME9, Delphi DCM — the modern generation that defines today's daily drivers.
