Well, you've already got one of them, so you only need to add one more. C'mon, you know you want to. Deep down your inner masochist is just aching to punish your bank account a bit more. Just a bit more. -
Sounds good....do you have a dyno run for it? Also, sounds like you should get an Ecutek tune shortly to make the most of the hard changes. -

But if you've got the flex sensor whats the issue? You just run what you can get your hands on. I can't see any reason not to run e85 if it's relatively local to where you live. -

Exhaust end of this month, and then tune after that whenever there is availability. Still tossing up between a pure 98 tune or a flex 98/e85 combo. The (lack of) milage in e85 isnt great. Start to get anxiety if i go for a long drive and there arent any united servo's nearby -
I mean I can be OCD'y but this is really over the top. At that point why not just run a full wideband fuel controller? Especially if you run 3 widebands. The system works pretty well, which is trimming low load stuff to be within a few percent of the base map. Pre-engine _change_ the base map was only 1-2% off, depending on ambient temp, elevation, etc. Under load the LS is really very straightforward to tune, enough that a wideband closed loop would be overkill. If I really cared (and I hope I don't) I can always just go back to the MAF system the car actually came with. Which does all those nice calculations for me (temp, altitude, etc), now that you can buy 102mm MAF's that do not cause restrictions.
