FreeFuel ECU patch - a flex fuel implementation to Evo ECU
Sweet, as long as the hardware / sensor comes with the provisions to tie into -AN lines count me in when I get back to the states.
It definitely needs tuned. You can take your base e85 tune and base 93 tune or whatever you use, but then the tables need blended properly. Our system has a bunch of blender tables. Its just like AEM's setup.
The tune session would involve the person going from say e85 to e70 to e60 to e50 to e40 to e30 to e20 and whatever their local straight fuel is.
The hardware has the ability to log everything evoscan can, so its pretty awesome.
As far as sensors go, the GM sensor works fine. And you can get the connectors that push on the ends and they certainly make AN push on connectors for it.

Its here. I'll get pics of the display lit up. I'm gonna wire it to the battery direct temporary to display what we have here.
It can log everything evoscan can, plus custom stuff. The box is quite nice. It reads eth percent, fuel temp, etc etc.

What size quick connect o-ring fittings are on the sensors?
Has anyone patched 94171715? (SD, Omni, v7, mods etc.)
This would be the ultimate setup, I live 30 miles from E85 and was going to avoid it on this build (was a pain being that far from a station). But this would allow for the ocassional fill up/fun
Amazing work by all involved.

Russell 644123 -6AN Male to 3/8" SAE Fitting
I would recommend the above quick-connect fitting over the plastic clip version.
You can see the recommended fittings installed on the smaller conti sensor in the photo of mine here:

I've been running the 9653E706 patch with my homebuilt ECA for the past 11 months. It works so well I no longer have to think about whether I fill up with 91 or E85. The only advice I can offer to anyone thinking of doing this is....what are you waiting for?
