Map1!

if you want, put 4 gallon of E85 to 12 gallon of 93 if its available in your area and run map5!

Should I keep running 93 only? E85 is cheaper right? It is available where I am.

I'd run map 5 regardless of what you decide with fueling.

What is the best fueling in everyone's opinion? Daily drive it in 5?

[foghat]

Fueling depends on what you have in your area. If you have e85, mix it properly and you can get gobs more power than running straight 91 or 93.

yes, put it on 5 and forget about it.

Map 5 regardless of fuel. Try for about 35/40% max E85 into 91 or 93.

Thanks! Do I ever use the stock map 0 or just map 5? Also, can I do like 2 gallons E85 and 6 gallons 93? What is the ratio? Do I always need to fill my tank full?

[Allaboutthehype]

No you don't need to fill your tank up full, if you google e85 calculator you can use it to see what mixes you can make, (most 91 or 93 at 10% ethanol in it and it does include that) It's also usually better to switch to map 0 or any other map and then back to map 5 if you use a different ratio and do a few WOT pulls so your JB4 can adjust to the new E85 mixture.

[az335iat]

Start with 30%...... 3 gal E85 & 7 gal of 93 or 91.

Make sure you look for jb4 updates
Keep your jb4 up to date

Thanks for all the help guys! Does it matter what I put in first E85 or 93? Do you guys like the E85 and 93 mix better then the E85 and 91 mix? What works best? What is best overall for the car?

[MasterWang]

I would mix e85 with 93 over 91 if possible.
Also, I highly suggest you log your WOT runs if you use e85 to make sure everything is running fine.

if the pumps are right beside each other, probably doesn't matter what you do first. If you have to drive any sort of distance between the 2, do 93 first. I think you are over thinking this to death.

I can just do this with the USB and laptop correct?

Rather be safe then sorry E85 is $3.11 a gallon and 93 is $3.99 a gallon here. So I'll be saving some money on gas obviously. Does gas mileage increase/decrease? Is this better/worse for the engine?

[MasterWang]

Correct.
Feed the USB cable through so you can set the laptop right on the passenger seat.

You likely won't be saving money on gas. Mileage is a fair bit worse with e85. Jury is still out but it is probably harder on your fuel components as well - unless with were specifically made with e85 in mind. i.e. flex fuel marketed vehicles.

Should I use just straight 93 then?

<sigh>

It depends what you are hoping to achieve. Me thinks you should do some searches in this forum and get all read up.
