JLT CAI Coyote

[tbrtuning]

When tuning a larger diameter intake like the JLT do you guys just multiply the MAF Airflow vs Period by the diameter difference in the intakes and fine tune like normal or are changes to the Airflow vs Voltage typically made?

Start off by multiplying by the entire airflow vs period (the lb/min values) table by the ratio of the old maf housing area to new maf housing area. After this dial everything in with long term fuel trims.

Thanks. That's what I was thinking but stumbled across Airflow vs Voltage data for JLT intake on an 08 Mustang so wanted to make sure that didn't need changed for some reason I wasn't thinking of.

Correct, Airflow vs. Period is the only thing that needs adjustment on the Coyote.
