Can I use a Ford Map sensor instead of a GM 3Bar for my Hondata?? I need to know for sure ASAP. I got a Map Sensor from a Lincoln Towncar. Will this work?

 

Sure you can use any map sensor you want....

Provided the output range is 0-5V.

BUT, will the MAP sensor from the Towncar read beyond ~10psi like a stock
Honda sensor? (I don't think so)

bump....NEED TO KNOW ASAP !!!

You already got your answer!! If you want the specs on the FORD map sensor you need to call a Ford dealership (probably will not be helpful) or ask about the specs on a Ford related message board.

I don't think so is not a definite answer. BTW, i will be using it with Hondata.

 

whats the maodel number on the ford sensor?

 

I think the ford maps read an output in Hz not volts. At least thats what I remember from the fords I messed with.

All Map sensors use voltage as a reference.

You're probably thinking of a MAF sensor. The GM MAF sensors read in Hz. They output a pulsed signal anyway.

 

thanks for everyone who tried to help but the Ford Map sensor is not a 3 Bar. i bought a GM 3 Bar from Autozone ($48) then i took it back becuz a friend is lending the one off his car while it's down.

Nope, ford 2 or 3 bar sensors output is in ohms not volts.

Errr...

First of all, you can't "output" resistance.

Second of all, a GM MAP sensor works by varying the resistance across two terminals as pressure changes, thus changing the way the input 5v signal is split, and thus you get a 0-5v signal.

If the Ford MAP has 3 terminals and varys resistance, it is safe to say that it is compatible. However, I can't confirm this, I do not have any experience.

the one i used was from a Lincoln Town Car and had 3 terminals but did not work with my Hondata set up for a 3 bar map.

 

I was a bit off on the ohms thing, its hertz.

This sensor sends out frequency variations instead of voltage variations. If you were to read voltage on the output wire, you would see a reading of around 1.5 to 3.5 volts. This reading varies slightly with altitude and does not tell you if the output is correct or not. It is merely an indication that the sensor is operating.

The frequency range of the Ford MAP/BP sensor is 92 to 162 Hertz (Hz). An engine idling at sea level may create 17"Hg to 21"Hg. At this vacuum, the absolute pressure is 13"Hg to 9"Hg. (Remember, absolute pressure is calculated by subtracting manifold vacuum from barometric pressure. The output frequency at idle should be 100 Hz. to 109 Hz. This signal varies as the manifold pressure varies.

ford wont work any way
