what the hell is that? and how does it make it produce more boost

 

if i am correct i think you will need a piggyback or some type of way to reflash the pcm to get anymore boost out of it.

 

i think that is what it is or atleast what the guy is making it out to be. 2bar is usally an upgradechip. i dunno $80 buck though.

I want to see a picture of it. Then I'll decide. For some odd reason it dosn't seem true.

Eeeh what the hell it's only $80.00. Someone buy it and try it out.

 

does anyone know if we have an afm or map? i've never really looked into the matter personally. i'm thinking with 12psi we would already have a two bar map, not sure what a one bar is capable of, accurately

i could be totally wrong on this matter, because i'm not educated on these things

 

i think someone was working on a piggyback but thats about it.

ok the cobalt ss has a mass air flow sensor and a map sensor a map sensor or manifold absolute preassure sensor is simply a resistor that meassures the difference between intake manifold preassure and atmosphere preassure. the computer uses this to monitor when the engine is under load to alter spark and ful mixture. if im not mistakking though the cobalt already has a 2 bar map sensor. what happens is this lets say a car has a 1 bar, once the manifold preassure reaches a certain point (boost) and computer cant monitor anymore your car will hit fuel cut.

 

Its the map sensor that comes with the car OEM.

The MAP reads absolute pressure. So if your running 14.7 PSI of boost (1bar) plus the regular air pressure at sea level 14.7 PSI (1 bar) you have to 2 bars.

 

How do you guys know all this stuff?? I'm thorughly impressed!!!

 

i do it for a living

 

Well, there you go. When can I make an appt to see you? How long is the drive from Toronto to Philly anyway?

 

thanks for the calrification ray

 

Eh, I won't trust anything peformance off Ebay. Sounds like a scam. Looks like a scam, it must be a scam

 

its not a scam, its just a stock map sensor...............

It dosn't even say in the listing that it adds boost. It just says that it reads 2 bar.

 

In the ebay post it says that "it's capable of 14.5 lbs boost"

 

Yeah thats all a 2 bar map can read. It's absolute not realitive so you have the 14.7 psi for the atmospehere (at sea level) and another 14.7 worth of boost on top of that.

 

heres from the add
says it only reads it.

 

this would be good for someone with an na ecotec that wants to add a turbo.
