Spec R ecu question

[LK Drifter]

Does anybody know if spec R's with the roller bearing turbos fitted as standard had the same ecu part number as the later non roller bearing turbo cars. I ask this as it appears they have different maps as standard.
Mart.

There are no fewer than 10 different PNs for JDM Spec R ECUs between 01/1999 and 07/2001 (the limit of the copy of FAST we hold). Half of those are for 4ATs.

The date changes don't match the date change for the non-BB turbos, so I'd say any map changes were made independently.
