LS1 Rx7 E85 Boost, thoughts?

Hi!

I finally got my rx7 tuned with the 2011 setup.
Search alot but couldnt find any really good info when changing to E85 on a boosted LS1.
I have no read out from my dyno. Why? .. Look here ->

Since i dont have any way to measure horsepower or at least changes in force i have to do some guessing.

I have not changed to E85`s lambda but still using gas. My afr read is 10.8 at wot (boost) and 18 degrees ignition.
Boost is at the moment at 0.65 bar (9.5psi)
Bone stock LS1 engine

What do you guys run? ignition, timing, camspecs etc.

I'm running e85 in my LSX RX7. You don't need to change anything with the WB02. You will need a better fuel pump and bigger injectors. Otherwise run the same settings on your 02 as you would gas and target for 11.5 afr. My last setup (ls7 w/procharger) liked it closer to 11.1 but the new setup LSX TD w/procharger likes 11.6 afr

if you had a strong bottom i would throw quite a bit more timing in than that for good gains

i am at 24* on 7psi right now, last year even with no IC even i was at 24* and 8psi
