MAP-ECU Install Questions (OBD I)

[dejacky]

What are some good-reliable methods to connect the map-ecu boost pressure sensor to the engine? I do not have a boost controller or fuel pressure regulator and will only run off the 5.8psi wastegate spring for the time being. Where should I connect the vacuum hose on the engine? :run: If reading boost at the intake manifold is the best way, what is the easiest way to set this up? Thanks in advance for all of you clubna-t folks' help!

ABC seems to be connected to 123. Some have said to connect after the throttle body, but where? :dunno:


Question #2: Where and how have you all mounted your air temperature sensors?

The stock Fuel Pressure regulator is the best place to tap for the MAP sensors



Mount the IAT in the IC pipe before the throttle body. Make sure its not in a place that could get heated by the turbo, and its in a fairly straight area of the IC pipe.


Some MAP-ECU users find it better to just use a resistor for the temp sensor.

Thanks :bigok: . Here's my next question:

MAP-ECU mounting idea: I like a similar layout like this because everything is at the same level and will not be a "bump" for a passenger's legs, thus decreasing the already little leg room available. It seems like I'll need to make 2 custom brackets to make this work, but I'm worried about anything shorting out. Can I just leave everything "as is" in the picture? It seems like three boxes will be plenty stable with the carpet over it. What do you all think?

I've decided to use 3M Exterior double side tape since it's easy to find, use, and seems like it will work great. Anyone agree/disagree?
