I finally got around doing some MAP sensor testing and contrary to what I have read, the e7ef-9f479-a2a sensor reads boost just fine.
vac is reading 90hz, atmosphere is 153hz and 15psi boost is 300hz
Based on the LHBH1 doc "The sensor outputs a digital frequency modulated signal in
the 89 to 162 Hz range" so wouldn't we be able to patch the MAP subroutine to handle boost?

sounds like it
Let us know if you get it figured out.

If anyone has a factory bin from a turbo escort or something, that would probably be a huge step in the right direction.

Re: Bench Testing MAP Sensor - Boost
Can you give me a little more detail on the bin you are looking for? Such as a year range, us, Australia, euro,etc....
I have a small collection. May be able to help you out.

Probably the US 1st gen 83-85 Turbo GT Escort assuming it uses a Ford ECU and not a Mazda ECU.
There was also the Mustang 4 cylinder 2.3 Turbo starting around the same era? That should be an EEC-IV for sure.

Re: Bench Testing MAP Sensor - Boost
What they said, but it may be worth looking at a bin from a mid-90s eec-iv powerstroke as well. Any eec-iv with MAP based strat, that came with a turbo from the factory. I don't think the country matters. Thanks

Re: Bench Testing MAP Sensor - Boost
How about a turbo 2.3L tbird? The part number for the sensor on a 88 turbo tbird looks like a e7ef-9f479-a1a. Very close to what you are working with.
Attached is XDF for the turbo 2.3 that is posted up on tunerpro website and lb3,la3 and 8ua which I show to be 88 turbo tbird.

Re: Bench Testing MAP Sensor - Boost
These bins do not appear to be correct. Shouldn't they be larger? Garbage data showing up in tunerpro.
