Map Sensors

[TurboTPI]

I am pretty sure that GN's and Sy/Ty's use the same map sensor, right? (if they are stock) Just woundering.

Re: Map Sensors

Correct

2 bar map came stock on SyTy & GN (maybe others

).
3 bar map came stock on TTA.

Re: Map Sensors

So how can you tell if it is a two bar map sensor or a naturally aspirated map sensor? I have like 6 spare GM map sensors in my garage, how can you tell witch ones are witch? Some have different color plugs.

Correct:

"MAP sensors, stock 2 bar on left (orange/red connector) #16009886 and 3 bar on right (black connector) old number is #16040749 new # is #12223861. "

Re: Map Sensors

also the 1 bar (N/A) has a different plug orientation.. 2 and 3 bar should be the same.

Re: Map Sensors

Or on the top side, looking down at the map sensor you can see the two bar has two tabs on the connector area and the three bar has three tabs. If you look you can see them on the two bar map on the bottom.

Re: Map Sensors

I checked GM parts direct and they say that the new 3 bar requires a new connector. Is this true?

Yeah, I read that too, ordered the adapter plug, but I ended up not needing it. Plugged right in for me.

Re: Map Sensors

correct me if Im wrong, but arent grand nationals mass air flow metered? This would eliminate a map no?

Re: Map Sensors

GN and TTA are both MAF ECM's. The 2 and 3 Bar Maps aren't wired to the ECM, they are only for the boost gauge.

Re: Map Sensors

plus adding a 3 bar to enable boost reporting for TurboLink on the Turbo Buicks and TTAs

Re: Map Sensors

dont rely on the plug colors, I have a 2 bar in the garage that is black.

Re: Map Sensors

i Looked in the box of partd I recieved when I bought my Ty and I found a 3bar in the box. Can I use it without a tune calibrated for a 3 bar?

Re: Map Sensors

actually that black 2 bar that I have has 3 prongs just like all the other 2 bars, so you cant go by that either, really no way to id them from the outside it seems.

And no, your chip and map sensor have to match.
