2012 Camaro Intake Duct Diameter

[Ricardo]

I just intalled a card MAF in my intake duct and need to calibrate it.
As a starting point I need to know the inside diameter of the duct where the sensor is located in the 2010-2012 Camaro.

Thanks for any info.

Heres a picture of my Intake Duct with integrated MAF:

Use a Corvette calibration.

You'll know real quick if it is close or not. Just multiply by a big factor if it's way off.

I was going to use a 2012 camaro Maf calibration table reworked for my LS1 PCM.
I have reworked both now, the Vette and the Camaro calibration.
The Corvette calibration seems to be for a bigger diameter duct as compared to the Camaro calibration.
I will try that one first.
