LET only came in dizzy form not dispac unless converted at a later date by the owner. iirc LET ecu's are pj or pk

They'll also have a small pipe on them that runs to the inlet, what is it your trying to figure out?

im turnig my dispack xe in to a let got the head, dizzy, loom. just wondering about the ecu's heard some was chipped key and chpping the ecu gets rid of the chipped key. also heard that there was an early and late type with belt setup im gunna run the new type

Theres 3 ECU's, PJ PK and HD, HD is the one that has the imobiliser built in to it.
There is 2 belt set ups, earlier one uses a manual tensioner and the later one uses an automatic tensioner, the belt covers are also different.

ok so wats the difference in the pj and pk ecu's

ok so wats the difference in the pj and pk ecu's

Ones got a PJ sticker on it and the other has a PK sticker !
No idea to be honest, both are interchangable tho.

only one loom for c20let and uses motronic 2.7. the PJ ecus were found in 92-93 cars and PK ecus found in 93-95. the early type had round tooth belt set ups and late had square tooth set ups, the later ones were supposed to be a quieter engine. dont be surprised if find either or of the ecus in any year of vehicle as they are interchangeable as already said above along with correct info regarding HD being the imobilised one, these are quite rare ecu as were a factory optional extra to have imobiliser therefore not found on all cavalier or calibra turbos.
