▁and ▁manufact ured ▁the ▁modules . ▁ ▁After ▁several ▁years ▁of ▁Intel ▁being ▁the ▁sole ▁supp lier ▁of ▁processor ▁ch ips , ▁Ford ▁persu aded ▁Intel ▁to ▁share ▁the ▁design ▁with ▁Motor ola ▁and ▁allow ▁them ▁to ▁produce ▁ 8 0 6 1 ▁ch ips , ▁but ▁only ▁for ▁consumption ▁by ▁Ford . ▁ ▁Over ▁the ▁years , ▁there ▁were ▁many ▁variations ▁of ▁E EC - IV ▁modules ▁depending ▁on ▁the ▁number ▁of ▁engine ▁cyl ind ers ▁and ▁the ▁types ▁and ▁quantities ▁of ▁inputs ▁and ▁outputs . ▁ ▁There ▁were ▁even ▁a ▁series ▁of ▁special ▁E EC - IV ▁modules ▁designed ▁for ▁use ▁in ▁Formula ▁ 1 ▁race ▁cars , ▁making ▁Ford ▁one ▁of ▁the ▁earliest ▁ad op ters ▁of ▁digital ▁electron ics ▁on ▁a ▁race ▁car . ▁ ▁These ▁E EC - IV ▁were ▁used ▁on ▁the ▁Ford / C os worth ▁ 1 . 5 L ▁tur bo ▁Formula ▁ 1 ▁engine ▁in ▁ 1 9 8 5 . ▁This ▁engine ▁with ▁the ▁E EC - IV ▁was ▁used ▁by ▁Ha as / FOR CE ▁F 1 ▁a . k . a . ▁Hass / L ola . ▁This ▁team ▁employed ▁both ▁Ross ▁Bra wn ▁and ▁Ad rian ▁Ne we y . ▁ ▁E EC - V ▁ ▁Add itional ▁performance ▁needs ▁drove ▁Ford ▁Electron ics ▁to ▁develop ▁an ▁en hanced ▁micro processor ▁named ▁the ▁ 8 0 6 5 ▁building ▁on ▁E EC - IV ▁technology . ▁ ▁Memory ▁was ▁expanded ▁from ▁ 6 4 K ▁to ▁ 1 ▁meg
