2005 1500 QC 4x4 Hemi

My mechanic friend of mine tols to to hold off on installing my CAI until spring because it will effect the computer due to the cold weather. He said the computer will dump more fuel to burn because of the CAI intake in the cold winter. Can anybody verify this?

Thanks

 

The point of fuel injection is the adjustment of fuel and spark based on the density of the air coming into the engine. I could be wrong though. Is this a real mechanic you talked to?

 

He works in the body shop of a local car dealer and works on his own cars. Not positive if he is an actual mechanic but he is very knowledgable about cars. He said that 90% of the time, the computer is skewed by the CAI in the winter and dumps more fuel.

 

What would make the computer all of a sudden unable to measure the needed fuel during the winter?

 

Not sure but he said it causes the check engine light to come on.

 

If the intake temp sensor detects cooler intake air,it enriches the fuel mixture.

 

That is exactly what he said. So I should hold off on installing it in the winter time?

 

It won't give you a CEL or cause any problems. I have a CAI on my Magnum R/T and my Dakota R/T. No problem summer or winter.

 

Why would the air be cooler with a aftermarket intake versus the stock box?

Is there some magic temperature below which the engine runs rich? If so what do we do, walk to work?

What could prevent your engine from running at the correct A/F ratio?

These are questions you need to ask.

Your friend is dead wrong, stay as far away from his advice as possible. Tell him he is wrong also. Nothing worse than people spreading bad information.

 

The only temperature reading the computer monitors that I'm aware of is the coolant temp. It will run the mixture richer until it hits normal operating temp. This is one reason you don't want to put in a cooler stat than stock without being able to reprogram the computer.

I agree with these guys---outside air temp is going to be the same coming into the stock inlet vs. a CAI.
