So I got a stratified tune for my 15 st3. it brought the car alive. My slots are as follows :

Slot 1 ? Full Boost, [email protected] 2500 93
Slot 2 ? Full Boost, [email protected] 2500 e85
Slot 3 ? Full Boost, [email protected] 3000 93
Slot 4 ? Full Boost, [email protected] 3000 e85

Now my question is for the 5th slot the low boost economy slot can I use that with the e30 mix in the tank? With that being said should I have a separate flash tune for the e85? What are the benifits? With the hurricane that just passed I had to fill up with 93 no e 85 available. Today I was able to put the 3 gal of e85 in the tank again and man I love it. With the E85 in the tank I am seeing over 23psi boost with everything else stock.

Really happy to hear you're enjoying the tune!

Yes, that low boost tune on a pure E85 flash tune is designed for E30 as well. If it's a combo tune and you have slots for E85 and pump then the low boost slot is for pump gas.

If you go back and forth between fuels I recommend either getting a separate E85 file or a combo tune to easily switch between fuels.

Ok I will keep this thread going.... I have read many threads about ign corr and most talk about negative adjustments. I do have a combo tune and wasn't watching it when running the e30 but I currently have 93 shell nitro bla bla bla in the tank... seems to be the best fuel down here in Florida they just don't have e85. Anyway I am running on the 93 slot and seeing ign corr max of +11 at the highest while getting on it. One thing I have to say since getting the tune with the exhaust crackles and didn't wanna spend the dough yet on a cat back, I took it to a local muffler shop and they deleted the muffler and welded the stock tips back on. Now with the rev limiters and the flat foot shifting and crackles I sound like Ken block going around a rally cross. Should I send ya logs and get you all to correct the + ign corr or is it nothing to worry about?

+11 does not sound right for ignition corrections. Have a look at this article and make sure you are reading the correct parameters on the AP:

Yeah I was looking at the wrong thing. Ign corr max. Now I am looking at each cylinder and seeing as high as +4.00 and actulally saw a -0.5 on cylinder 1 and a -0.06 on cylinder 4.
