Holley E85 ????
My 7's only had 3 dark threads when I pulled them, too cold. You have to read them after a while and see.
Most authorized dealers can set up a tune (global folder) for you that should be a bit closer than what the "custom" global folders are.
As others have stated, Holley reads in lambda. Set the scaling to gas, and tune like you would a gas engine. The Holley will make necessary calculations in the back ground. I've sold over 100 systems in the last few years. They are powerful, and offer a multitude of capabilities for the price.
