I wish I could have spent more time watching them tune yours. It was very impressive. It's great to see guys coming together on a build like this and improving the Z greatness! I love this E85 gas. On a side note, when we put E85 in rays car with the Haltech, it was reading 63% as well. His was a mix of E85 and what ever was left in the tank. On John Davids Z his tank was bone dry and filled with E85 which registered 68%. So the pumps that read minimum 70% ethanol there are sitting at about 68%. probably loses a couple % from the plant and sitting in the tanks at the station. We also tested some so called E85 that had a minimum 50% on the pump there. This showed up at 51% on the Haltech readings. I would never use this stuff in your Z, so watch out for that. Ours in Nebraska is all 70% minimum, and I have seen a few pumps in Phoenix that are 85% min. As you keep refilling with the 68% stuff your ethanol content gauge should keep rising until it hits that. And come to Branson next month!
