Might be a dumb question, but I couldn’t seem to find the info.

Is there anything special about the 1989 CSX VNT ecu ? If memory serves me right it is an SBEC based on the 1990 electronics ?

If I am looking to start tuning the car myself, do I need a CSX specific ecu to have socketed or can I have any SBEC sent in for socketing ?

Previous owner replaced the VNT with a Mitsu turbo and manual boost controller, so I don’t need to have a way for the computer to control the VNT
