" Things definitely get a bit more finicky running 100% E85. It seems to be a bit more sensitive to temperature changes and tuning requires a bit more than just adjusting the scalar.
E50-E60 is a good mix to work with as many of those issues can be avoided, power gains beyond that have yet to be proven, and frankly that's certainly not why I run 100%...I do so for a couple other reasons.
you must be Chris L?
pats...Yes, his tune is pretty conservative as neither Steve K. or I tune very aggressively and IIRC Chris isn't FBO. We don't really tune for others but Chris was wanting to run 100% E85 and since Steve and I both run 100% E85...we kind of worked on that together..but Steve K did the bulk of that. We leave the tuning for others to Wedge who has much more experience in that arena than myself.
As for your pump...I really hate to say it wasn't a good choice because it may very well be with the right setup. I really have no first hand experience running it inline, just solo in the bucket and it was a very good pump for that...too bad that install is not very DIY friendly and I don't think anybody wants to take on that retro-fit for others without fab'ing a new bucket.
As for the lambda targeting on E30...I don't see anything wrong with it at E30...but when you start mixing to say E50 or E60 and only change your scalar....you can run in to issues and the car may not run well or to it's potential. The E30 map is a pretty good base map though...IMO "
