Cool truck and nice work so far.

On page 1 you have a post mentioning draining the E85 out because it’s not available during winter months. Not sure if you’re aware but the Holley has the ability to run a Flex Fuel content sensor that tells the ecu the ethanol content of the fuel. It doesn’t matter if you have a tank full of e85 or have it diluted down to 20% ethanol content the ecu will adjust the fuel trims for it. This is separate from the “self tuning” the ecu may do to maintain a target afr. Either way no draining of the tank or adjusting the tune for ethanol content is required when using a flex fuel sensor.
