OBD1 From OBD2b (I Am confused)!

[Dodo Bizar]

The 96-98 EJ9 dizzy is a weird one, I know it exist in a 1.5 litre car in the middel-east and in an Aussie 1.6 litre Civic as well.

This 'special' dizzy lacks one sensor (CYP) and has different signals. Normally magnets/spools are used to measure pulses, but in the 'special' dizzy a LED light with light sensor is used instead, giving another type of signal.

The OBD1 ECU's need the magnet/spool type sensor I believe and need the CYP sensor I am sure about. So that is why 96-98 EJ9 owners like me are screwed and 99-00 owners can save money and effort.

And dont you have to change dizzy?

OBD2b (1998 onwards EJ9's) dont require dizzy change only OBD2a (1996-1998).

Didnt knew ! Why is that?
Lucky bastards !
Hehe
Cheers

This just gets stranger and stranger, Im running an OBD2A ecu, with a nine wire OBD1 dizzy (two plug type) and the build date of the car was november 1999, my engine must have been built with surplus parts
