P4532336 Good used, Mopar Performance SBEC engine controller. For 1990/1991 2.5 engine w/automatic. Also works in 5 speed cars but the automatic version has slightly less torque than the 5 speed version. Use as-is or as a spare or use as the core trade in for a re-calibration.
Removed from a running car we bought wrecked in the rear several years ago. It's a '90 or 91 T1 Federal Computer from a Daytona. The MP cals have some stuff in there for road racing that keeps the revs higher between shifts, It also has some things to richen up the mixture earlier.
