How much E85 can you run (E30?) with a piggyback controller? 1?

Thinking of Dinan or JB4

Probably around 3-4 yes but it's worth it to test the E85 so you can know exactly how much ethanol is in the tank.

If you get a JB4 you can send in your logs to Burger Motorsports and they will review them, it helps if they know how much E is in your tank in case they recommend more or less.

Main thing with E30 is the risk to run a little lean, just send in your logs to BMS, they'll see it and let you know. But yeah its basically safe. I daily drive JB4 map 5 on E30

E30, the number of gallons depends on how much fuel you have in the tank.

Add 4 gallons to an empty tank will be a lot more than E30.

I usually run it until the gas tank is empty, then add E30 and 91/93.

Please note, that the fuel-it kit is handy since the ethanol mix at gas stations is never accurate,

I got that. What I meant was 3-4 gallons of E85 then mixed with 91-93 til full. So, 9-10 gallons of 91-93. What is this Fuel it kit?

It allows you to check the exact Ethanol mix using an app on your phone.
