Hey, new user here...

Started with E10 from the local stations and started data-logging.  Enough of a difference to justify tuning for E10!

Now I'm making each tank progressively more alcohol based until it trips the CEL or I see a 25% error in LTFT's.

Then I'll start actually tuning for E85.  Once I have a good baseline, I'll be sure and post the dyno (before and after). 

Been lurking for a few days and decided to join.

I had starting issues (E70-80) before the CEL (E81).

 

Hope you enjoy your stay.... Last one out turns off the lights.

33.4% Ethanol  mix.  CEL came on when I THOUGHT about turning the key.  Reset CEL after reflash and I'm running %1.07 LTFT's (7% error, not bad for a first time guess).  Nice low end torque, can't lug the engine, it just can't go low enough RPM wise (It's pretty cool!).

Wow... Outstanding experiment.

 

It seems the newer Fords are easier to program than my older Nissan.

 

Congrats!

 

What program do you guys use to do the tuning?

Very cool.

 

I have to pull the EPROMs out every time I want to adjust the program. And the programming software is limited.

 

I'm interested in seeing your dyno results

110lb/ft of torque at 1,300 RPM's, try that on gas!

My flash device wasn't talking to my laptop, so we couldn't correct the AFR.

You'll note that the shop has never run an alternate fuel vehicle since the AFR's are still gas referenced.

(Wideband O2 measures Stoich, and the display is reference to the fuel being used)

Very solid runs that never suffered from heat soak, I got more power on each run.
