Map Sensor = The Turbo Coupe motor uses a BAP sensor (Barometric Absolute Pressure) to make corrections to the fuel and timing tables based on different altitudes, the Mustang uses a MAP sensor (Manifold Absolute Pressure) to perform this same function. The MAP sensor will work with the Turbo Coupe motor by simply unhooking the vacuum line that runs from the sensor to the manifold or vacuum tree. Thus allowing the MAP sensor to read outside barometric pressure instead of manifold pressure. Do not plug the MAP sensor vacuum port on the MAP sensor itself, only the manifold or vacuum tree port. Leaving the MAP sensor vacuum port open allows the sensor to read the outside barometric pressure instead of the manifold pressure it would normally if connected to the vacuum source on the manifold.

The instructions are acually a bit complicated.Can some on simplify them for me?Thanks!


Optional Stock Electronic Boost Controller = The Turbo Coupe computer is equipped with a electronic boost controller valve. It is recommended that you upgrade to a manual boost value for higher boost pressure but if you wish to retain the stock electronic boost controller valve follow the below instructions. Run the Pink w/Black stripe wire from the boost controller valve to Pin wire 31. Splice in the Red wire from the boost controller valve to pin wires 37 and/or 57. This is the Red wire that was capped off when hooking up the VAM meter which was from the EGR vent solenoid. Do not remove pin wire 37 or 57. T-in or splice in to the existing connection.

Where is this stock Boost Controller on my 87 TurboCoupe?

[pepegurr]

it is located on the passenger side inner fender it has a wire plug and vacume ports.

On the MAP sensor, disconnect the vacuum line from the MAP. Follow the line up to the vacuum tree on the firewall and remove the line there, then cap that port.

Here's a pic of the boost controller.................

I checked if there was vacumm line...No Vacumm line from map to the tree. my car still hesitates....do i need a new BAP? or is it another problem. The car hesitates on idle and running.Please Help thanks!
