3 Bar MAP and 87 CSX LM

[johnl]

OK, I've been limping along with a 2 bar MAP in my T2 GLHT. Now, I've finally got both a 3 BAR map sensor and an 87 CSX LM (no map sensor on board). Also got the correct connector and micro pins.

Now what? :o :confused:

I do know of this link - http://hhscott.com/93tmv/3-bar_map.htm
but it is not for a PM/LM set up.

Do I trace the wires that are in my 86 GLHS T2 cal (that hook up to the existing two bar map sensor) back to the pins - then do I just hook em up? Anybody got some hints/tips? Better yet, just tell me what to do:)

There is no stock calibration that uses a 3-bar MAP sensor. To use the 3-bar you will need a custom cal from either one of the vendors or make your own.

Yep, stock cal is a no no. You will need a socketed LM and a 3 bar cal

DEFINITELY DO NOT run the 3bar on 2 bar electronics, been there broke that.

i too am curios of wiring in the underhood map....

Putting an 87 LM in an 86 car requires some pin swapping.

Check here for diagrams to compare:

Just swap pins around and run your map lines as indicated on those.
and...Definately get a custom cal to run the 3bar map. Super easy.

Hey John, if you got an extra board I can socket for you. Butch
