3 Bar sensor

[EcoBrick Bob]

Torrie discounts Ford parts.  You might find a cheaper source, but you know you're getting the right part when you order from Torrie.  Same from Livernois. The numbers on these sensors are very similar.  I have a damaged 2 bar sensor and the 3 bar sensor  in a box & numbers are almost identical except for last letters.  The 3 bar sensors are made in Germany.  It's not like you are going to save big $$$.  Maybe $10-$20.. at most.

Let me know if I understand correctly:

The item #4 in this picture is a 3 bar MAP sensor that my SHO came with



And the item #9F479 in the next picture is originally a 2 bar MAP that I need to swap with the 3 bar I just purchased

[TaurusBuilder]

Still confused on why I need this. But I want to order it today if it adds performance. Just need a link

Yes Pelo.  You are swapping out the sensor on top center of the intake manifold.

The 3 bar sensor by itself doesn't mean more boost.  What it does is allow your tuning specialist to tune your car correctly at boost levels above 1 bar. ( roughly 15 psi).  So... this means that your stock turbos or custom turbos can be tuned to provide higher boost levels, depending on other mods and fuel choice.

Say you swap for the 3 bar and get the tune that takes advantage of it. Is the stock tune able to work ok with the 3 bar sensor?  I'd hate to have to put the 2 bar back in just to revert back to a stock tune say for a dealer visit.

Nope, if you go back stock you have to swap out the MAP sensor. Sensor can be changed in less than 5mins.

Thanks for the info. I'm glad I asked about that. Never thought about that scenario before.

Bob, your so smart.  I think most people can figure out a map sensor does not automatically tune itself...  Lol

You're*
Also, i'd doubt your assumption. Most people likely don't know what a map sensor even is.

ordered AA5Z-9F479-B for $83 plus shipping from Tousley Ford. He says the number is
AA5Z-9F479-AB on the actual part just like the picture someone posted on the previous page. He pulled a few MAP sensors from ecoboost vehicles since he was curious about the 3 bar becasue he has a Focus ST and likes ecoboost performance.

He comparred several MAP sensors and couldn't tell the difference in them at all. I figured the 3 bar with the part number above would have 3 wires / bars / sensors going through the actual sensor part kind of like a MAF sensor has those delicate little bars in there that you clean.

Oh well I ordered the right part for a good deal now bring the XV1 tune LMS !!!!!!!!!

[FoMoCoSHO]

Can't go wrong with Tousley, they rock!

[EcoBrick Bob]

Do you think a 3 bar sensor holds more liquor than a 2 bar?   OOPS...

[BiGMaC]

EB... No, the 3 bar sensor just finds a higher concentration of ethanol sales locations in a confined space so you don't have to drive.... sorry, couldn't resist

[EcoBrick Bob]

Damn... I thought you were kidding... but you are spot on!!!!  I even found one with 15%... and it attracts 85% stations like a sky hook!!!!

[68_GT]

I assume there is no reason / benefit to install my 3 bar until LMS has their XV1 tune ready right ? I mean there's no benefit with out the new tune so why bother asking them to tweak my current stage 3 or 4 tune just to run it for no reason in the mean time ?
