Air temp Sensor

[Kdawgboostin33]

Just installed an aftermarket (Haltech) computer, And am having issues with this. One of these being they have installed the Air Temp sensor in the Back of the Air Box?? I have just been told it should be connected to the intercooler piping just after the Throttle Body. Does anyone know the correct location??

[kjb_r33]

correct location is AFTER intercooler (preferably manifold), ECU needs to know inlet air temp to make trims to fuel.

Cheers,

How would u tap it into the manifold?

Throw it in the piping in front of the trottle body, should be easier, mine worked fine in this location.

Drilling and tapping the inlet manifold isnt a nice idea as you would want to remove it to enure no filings/swarf are left behind to ruin your engine.

yeah man i think what u have is a delco v8 vn-t commie air temp sensor..... it needs to know what temp air the engine is getting.... tap it in cooler piping about 100mm b4 the throttle body and u will never have another problem again.....remember to thoroughly seal it to prevent leaks.....

Thanks guys will give it a go. If it was causing problems. What would these be

It would be using the air in the airbox as a reference for air temp compensation, when in reality that reading is likely to be a little different to the air post turbo and intercooler, whose temp is more critical when trying to control the combustion process.

In all reality i imagine if your not cooking the air with the turbo with high boost and your intercooler is reasonably effecient, then id hazard to guess the temps wouldnt be all that different and wouldnt really impact the tune of the engine.

Thanks for all your help
