Thanks really appreciate it! Question, not to sure if you’ll know but I put e85 in and my fuel gauge doesn’t really keep up with it? It looses gas then “refills” itself I’ve burned more fuel than what my gauge shows is that normal? First time running e30 in this car.
Kind of normal yes. E-85 has less BTU's so it takes about 30% more fuel to get the same AFR. BUT.... It has much higher octane so it's worth it. The reality is that 30% is for full E-85, you're probably running around E-30 so it's going to be much less.
Could you check this one to?
Are you talking about your fuel gauge not reading full? Or just the remaining mileage estimate bouncing around? The latter will happen as the car re-learns. When I'm running E30 around town, a full tank shows 320-330 miles remaining (averaging say 20-22mpg), but on the highway without ethanol the range will increase to say 370-380 even as I burn gas, because it's seeing me get 27-28mpg and adjusting.
30% of your tank having 30% less energy/mileage should multiply to about a 10% overall loss of mileage on E30 vs. premium. And that seems about right in real world driving, call it a couple mpg.
This is a clean log to learn on, since you have a single WOT through three gears (start with RPM, Gear, and MPH columns to get your bearings). Target boost, fuel pressure (fp_h), and AFR as as expected. Ign1 (overall timing advance) increases with rpm with no corrections (generally 3+ degree drops), and ign2-6 (timing drop relative to cyl1) are all zeroes.
