JB4 + tank of E30

[wrk2hrd]

I have a log with 91 octane (non-ethanol), 10 gallons of 91 octane (non-E) + 5 gallons of E85 = E17, and now I want to run a tank of E30 and get a log and compare the 3.

I bought the fuel-it analyzer and connected it to my JB4 to get the real-time # of E in my fuel. There's definitely a SOTP power improvement running Map 1 on just 91 oct vs Map 1 on e85 mix (e85 mix log has much less timing being pulled up top). Ultimately hoping to try and successfully run Map3 on E30 and then daily drive Map 2 on E30.

with the fuel it, how much E85 does it ask you to fill when filling from empty.

I only did one tank of E85 (5 gal) and the rest 91oct.

I now only run straight E30 in the car on map 3 and pedal commander on Sport. Entirely different car.

I don’t have fuel it kit, but I do 6.5gallons of E85 and rest with 93. Not sure if I have been mixing right but the JB4 app shows E28 and sometimes E31. I’ve been able to feel the difference tho and my best 0-60 on Map3 has been 4.4 sec. Waiting to get a TCU tune and see how great that will be. Thought about pedal commander but I’ve read lot of people having issues and limp modes. How long you’ve had yours? Would that be any different from Sprintbooster?
