Knock retard on 110 octane at start up?

.78 is safe. .81 is fine if you want to push it. .76 and below is too rich. If your car is right you can run all day long under any amount of stress @ .78 (11.5 on 14.7 regular gas) You should invest in a fuel sensor for alcohol content. Then the ECM will adjust timing based on fuel when tuned.

When you say an alcohol sensor, you mean to convert to flex fuel with a flex fuel sensor? Not sure I know what an alcohol sensor is or where it goes. Flex fuel I've heard and seen the kits.
So with the sensor, I would tune using non-ethanol, then if I fill with E10, the sensor will correct it.
My last quick run WOT was stable at .77 on 92 E10

Do you have a log?

This is the kit version. I bought just the basic sensor. Then wired it and mounted it hidden in the fender-well. Then you build a timing table for 91 no ethanol. Build the scaler and adder table and forget about the fuel blend. As far as you want to go until you run out of injector. I run out at 1200hp and 60% with ID1050s. When I do my blower change I will have to go to ID1350s to fuel the 1500 HP it should generate.

That is the kit I was thinking about. The more I learn about this tuning stuff, the more I realize I don't know anything. Reading through Greg's books and his engineering explanations of the math involved makes my head spin.

I didn't log the last run
I don't have flex fuel here so I wasn't going to buy the sensor. Do you think it will really make enough difference for just E10 to justify the cost?

If you aren't going to run anything but E10, the flex fuel sensor isn't worth the money or time to install.

The only thing I could see running is the 110 that the local VP station sells but it's $8.99/gal. It would be for track day only if I ever get there! LOL

If we had E85 here, I would definitely be running it, but that would require more fuel pump, injectors and a flex kit. Time tuning...A hell! lol

My wife would strangle me if I spent the money it would take to build a 1500HP car. Well, she would expect her cut at least so now it's twice as expensive. LOL
You planning on a Kenne Belle 4 liter?

Nope, just a little 2650 roots blower.
