was wondering because i have a check engine light on saying i am runing rich but i am not.
was wonder if i change maf to 2.0 will it take it away tried to erase rhe code but it comes back.

 

if its from the maf sensor you are better off buying a new one that fits directly with the 2.2

 

I had that check light problem, I was really stressing the balt alot one day and was running Cheveron 91 octane, it went away after i eased up on the petal.

 

i believe the MAF sensor is the same across all models...but it is a physical direct replacement

 

Nope. The 2.2/2.4 is essentially the same, they read N/A air intake velocity etc. The F/I models (SS/SC & SS/TC) have a different MAF that is calibrated to read the F/I air flow etc.

 

are you sure? That sounds more like the MAP sensors in our cars. I know the 2.2/2.4 MAO is a 1 bar and the SS is a 2.5bar, but since our MAFs are frequency based and not voltage based, there would be no different calibrations between the sensors.

 

Think of it like this. Cars require tuning based on MAF readings. So, you take a N/A car and go F/I. You have to tune. Well, taking the theory that the MAF sensor is the same in the F/I car and the N/A car, then why not swap them? I mean in theory you wouldn't have to tune then because the car knows how much air is coming in right? MAP Sensor reads the pressure inside the manifold, the MAP in a F/I Car is going to be higher because of higher manifold pressures as opposed to a N/A car that is taking in about atmospheric pressure (1Bar), so with the SS/SC at about 15PSI that is about 2 Bars of pressure, Atmospheric + Boost.

With that, the MAF Sensor reads higher in the F/I cars than in the N/A cars. I.E. Low to High Freq range in F/I and Low to Med in N/A cars.

So, both the MAP and MAF Sensors are inherently different from each other depending on N/A or F/I Classification. Either way, it will need to be tuned/programmed for.
