Map Sensor Question?

[MY 85 GT]

I was wondering something...my map sensor is from a Speed density car but it is now a MAF car..i looked up the part number from 87 to 89 and there different part numbers would that hurt anything?

nah, its the same thing

a little clarificaion


Speed Density uses the vacuum port. That's the MAP part of the sensor. In Speed Density setups, when the Key is turned on, its takes a Barometric reading, and updates the Barometric under certain conditions. Like under a load when vacuum is low. When its not taking a Baro reading, its doing the MAP calculations based on Manifold Pressure.

you sure why are the part numbers different then when you look one up for a SD car or one for a MAF car....lol

I know mine doesn't have any vac to it being it is MAF now but wouldn't the inside electric part be different in some way ??? if you know what I mean..

bap and map sensors are the same! the only reason ford changed part numbers is because of the hose deturent (cap) that was put on the hose fitting. On the early cars if you pull the lable off it has the old bap part number on them !

OK COOL..just was doing some reading and saw someone say there were different...

good technical read here

You can use your MAP sensor with the vac line removed as a BAP sensor. It should run fine.

If part ever fails, i'd replace it with an 1989+ BAP sensor

This! I converted my car to MAF last summer when I added the supercharger. I removed the vacuum line.

It runs great.

Ok guys thanks just was thinking that last nite was wondering if it would be ok to leave it that way...

 

[88LX5.Oh]

It it wasn't ok, then hundreds of people, myself included, would be driving around with half assed MAF conversions.

Some do considering a lot don't wire up the VSS and fuel pump connections.

You do have a point there. But thankfully I was smart enough to go ahead and do these steps lol
