What's a good blend for e30 map, 3 gallon of e85 and the rest 93 oct?
You need to test your e85 at the pump and your 93 to determine actual ethanol content of both. Then you can use an app to calculate e35 which is what im running in that log.

Ethanol tester:
Boost Monkey E-85 Fuel Test Kit - Ethanol Percentage Sample Test https://www.amazon.com/dp/B08132XZBX..._LV80EbAHGR5MC

Here is the app I use:
