Default MAF Relocation

Has anyone tried to relocate the MAF to the back of the air bridge? Seems like it shold work just fine, and should be quite easy! GM thinks it better for th C6.

I have the separate MAF sensor..the newer is integrated into the MAF plug (I think). I've had it in both locations. It seems to work the same.
It's said that in the Blackwing air filter location it reads cooler making the acceleration faster then in the air bridge where the air is warmer. It's said to be such a small gain if any (HP or MPG increase)until it's a personal preference. IMHO

I have mine 2 inches from the throttle body because callaway engineers agree that's the best place for, I installed the callaway honker and the MAF is relocated next to TB and is working great.

The reason I was thinking this is because I had to get rid of my blackwing due to pinging. I have my fog light housings cut open and I know all that blasting cold air had to be upseting the readings at tha MAF! For know I went back to the stock air box with a Z06 lid and a K&N.

I have the Blackwing and had the MAF sensor installed in it, but changed it back to the coupler near the TB. I also have the cutouts for cold air. When I have the Superchip tuner installed I get a ping, when the SC is installed and back to stock tune there is no ping. Lead me to believe that the SC was advancing the timing. SO next cure is to have it dyno tunned.

I think Callaway were putting the MAF sensor in the Blackwing air filter. Also as stated the C6 has the MAF in the airfilter..there is so little a gain until it doesn't matter I believe. IMHO BTW mines is back in the coupler near the TB.

Callaway engineers relocated the MAF sensor in the C5 Honker design in order to eliminate the restrictive over-the-radiator "air bridge". Their objective was to provide the smoothest path for airflow possible, removing all possible restriction. Air doesn't like to change direction. The air bridge's complex shape produces turbulent airflow. Turbulence reduces mass flow rate. So getting rid of the air bridge was critical.

Honker Installation Instructions, 2001-2004

The engineers discovered that the MAF sensor can't be relocated without other design considerations. Drivability problems occur and DTC's are triggered. The orientation of the MAFS relative to the rest of the intake tract is crucial.

Being so late to introduce a C5 intake allowed us to compare all the other available intakes. By the end of development, there was no intake system that could provide the same airflow as the Honker.

I believe you're confusing the MAF (Mass Air Flow sensor), with the MAT (Mass Air Temperature) sensor. 2001 through 2004 C5s and Z06s have an integrated MAT in the MAF. 1997 through 2000 C5s, have a separate MAT located in the airbridge.

Thanks for the feedback on a great product!

Thank you ..thank you for this valuable information..this should put stop the wondering (in my mind anyway) of the benifits of relocating the sensor.
