E85 Timing
I think our ecu has some good enrichment strategies already built in, plus ignition advance to make good cold starts. You will just need to tweak it for the winter.. on the summer you will need to change the start up area. It will be a challenge i think for piggybacks to use one summer and winter tune esp on extreme temps changes
One should always stay conservative on timing...use boost to make the power especially with e85. Timing equals...KABOOM!..One thing I noticed you will hardly ever get knock with E85. In time however if your making over 350whp them stock rods are going to buckle like never before..guranteeeeeddddd.

10k on 10-17 pounds made over 400wtq drive it hard im buying time
I agree. You cannot optimize timing street tuning, period. The dyno is the only way. MBT is MBT, only a dyno graph will show it. I ran 9 degrees advanced timing near redline with WMI on pump gas.... nobody would have the ***** to just plug in those numbers street tuning, that's asking for detonation.
You need to get the timing where it needs to be, if it is too "conservative" as some say your egt's will skyrocket.

my car is street tuned all day every day
went to a dyno threw down 400 some people are just cow boys. im now running 17-19 psi stock motor feels to be about 50 hp i love the ethanol. btw im trying to pop my motor build this winter if not another stock motor one localy for 300 with 27k on it

I have a 50 trim t3/4 turbo with a .63 exhaust housing running 9.8 to 1 compression with a 100ml wmi jet and a 35% meth mix. I want to run 22 psi. Where should my timing be?
I don't know anyone in the world who could answer that question without Dyno tuning the car.
Beyond that, WOT is one thing, but optimizing timing (especially with a standalone) can ONLY be done on a dyno.
" ok lets drive up a hill at -15 vacume @ 3000 rpm, my butt feels an increase in tractive effort" LOL "
I had to think about this for a few minutes... at first, it made no sense to me. I think what you are saying is one should have the smarts to have a "general" idea on where the timing should be?

Uhm, 14 degrees during peak tq and tapering to 17 !
LOL
So, this isnt really a build thread, but I ran at the track today at IFO... It was 95-98* out all day - it sucked bad 
On street tires = bad idea
Best time was like a 14.2 lol
Traps were between 110-112
Also I was getting massive heatsoak - iat's were really high and causing it to run really rich - like 10.5-11.0 (on a gas scale)
This was on my setup on 17 psi (built bottom end - 9:1 comp, E85, 60-1)
Should be going to a local track soon at night in oct when the temps are 60-70
