Has anyone upgraded their 1985-89 ECS Module to the ECS used on a 1990-96 using part number 16038331? I've read several positive articles on this upgrade. Net net is that the knock sensor is very sensitive on all years, but the ECS used on 1985-89 L98s generates way too many knock counts, causing ECM to retard timing (even at WOT).
