I have an 87 CSX I just got running 3-4 weeks ago. The location of the MAP sensor is on right side strut tower as is normal for most vehicles I've dealt with (up to 88?). However.. the car has a hi perf. computer so I was told, with the MAP installed in the module (behind the right side kick panel). I guess my question is on a stock 87 CSX where is the MAP supposed to be located ? Confusing...
Thanks to any and all who respond. G.P.
Map should be on right strut tower (external) like you thought. I would pull the computer out and read numbers on the outside as well as the on circuit board. Seems odd, but maybe someone installed either a 86 GLHS LM or case is a 86 case with 87 circuit board inside. On early 87 cars, they sometimes used a plastic cover which fit in place of where the internal MAP sensor would have been on previous year. If it is an 86 GLHS LM, then a couple wires should have been changed on the harness. Power loss light and distance sensor (VSS) needs to be changed. Is external MAP hooked up? Is internal Map hooked up? Post up what you find.

Might have come from a GLHS where they wanted to keep it "stock" so the MAP was put on the kick panel module
MAP situation is resolved. LM is behind the kick panel but my fault didn't notice the MAP was just a cover, correct MAP is on the strut tower. LM is part #p5249671. Black/yellow and purple wires are tied in somewhere else.
Did the 87 CSX come with a slider cam or roller cam? There is a roller in there now which is fine by me. How much vacuum should I be pulling at idle? Not sure if the stock gauge is very reliable. Still runs good. My 88 T2 was 18 inches all day at idle. Thanks to any and all who respond.
The 87 cars came with slider cams. The car should pull 18-20" of vac.
