This ECU came out of a 1997 Jaguar XK8 convertible. The car ran but had a bad engine with oiling problems. That being said I can't tell if it would've run smooth without misfiring and check engine light because of the mechanical failures.
The pins are all clean and in place and the outer case has no corrosion. The electrical case where the ECU is housed was clean and dry. It had a misfire update done when it was nearly new and I have a photo of the sticker for that.
