Here is what you need:
-86-87 ECM
-3 Bar MAP, with corrected feed voltage
-Power Logger and Windows laptop/tablet
-SD2 chip from Turbo Tweak
-Wide band sensor
-Manifold Air Temp sensor (MAT)
-Lots of reading/Studying
Fast XFI will work as well but, you still need the PC, MAP and MAT a wiring conversion harness, and the reading.
Hope that helps.
