Customer unit Cosworth ED (not badged as Ford Zetec-R) for non-works teams was also made for 1995 with about 580 bhp for Minardi, Simtek (called the EDB), Pacific Racing (EDC) and Forti (EDD) teams. Minardi realised the power deficiency before the season and asked Magneti Marelli to develop a replacement engine management system, with which the engine was called the EDM. Cosworth later updated the ED to ED 2/4 for Tyrrell and Lola with (94mm x 53.95mm) displacement for 600 bhp, which was used until the end of season.
