92 octane (haven't found anything higher near me in WA). I get about 280-300 miles to the tank in sport + manual which includes city driving. Decided to cruise in auto for the boring highway stretches of my last spirited driving day and got about 350 miles to the tank. I wouldn't be surprised if this did 400+ to a tank on an economy run.

Are you tuned or have the flex fuel add in?

LPFP, PI, PI controller, flex fuel and tuned. You really need all to run properly.

Did you swap out the factory LPFP with a higher flowing unit?

I added an additional (external) It alone is supplying the PI

I do a lot of city driving and I hardly get 230-240 on a full tank. And I am in normal mode all the time. What am I doing wrong? I put in 91 and that's the highest I get around here in the bay area.

Hills I guess? Stop and go traffic also is pretty bad for fuel economy but even then I can get 20-22 MPG, so maybe that's the difference.

In sport + manual, I'm not constantly redlining it. I will go into 7th or 8th on the highway if I'm just cruising, and really only drop it into 5 or 6 if I'm going for an overtake. I do downshift early approaching lights for the crackles on the overrun -- that's my big reason for sport + manual.

wow
id like to see a log.

Just trying to learn...which part of his post made you say "wow?" The 5 gallons of E85? Or running the JB4 on Map 5?

I put 3 gallons of E85 in tonight and ran on Map 3 and finally saw improvement I was expecting.

Trapped just over 120 according to Dragy. On Map 1 with just 93 it trapped just over 117. With just the downpipe it was consistent 116.

The 5 gals on map 5
No way he didn’t have trim and lean issues if doing pulls

Gotcha. I'm on my first tank of 3 gallons E85 on Map 3...do you think that's reasonable?

What would be a good mix to try for map 5? Or do you not think map 5 is a good idea?

 

[Rocksandblues]

first and last... i have JB4 but am NOT an expert. Specific questions should be asked to THE experts on burger site.

but, map 3 is a plus xx boost map. map 5 targets a specific boost number.

The experts say to look at logs and verify trim/lean issue before trying next map.

3gals should be fine and safe
