Here's an odd question......with it being colder outside, is there a way I can hook up a switch, or use what used to be the a/c wiring to be able to switch on and bring the idle up to say 1700 or so in the staging lanes if I need to put a little more heat in the engine quicker? Kinda like using a lean-out valve on my alcohol cars. I like to pull into the water at 180 but sometimes I need to get it there a little quicker.

Any harm done if I just drain gas, flush, and fill with E85 and adjust the tune? Stock 19# injectors with 255lph pump. Will everything handle it?

19s on E85 will only support 195hp. A stock engine on e85 makes 240hp.

You should have 30s minimum to run e85 on a stock engine and at least 36lb minimun if its modified.

Details are in the pre tune info write up

What lambda should I command for the E85? I run OL all the time. I run it at 1.0 on C110 race gas.

1.0 is where the car makes the most power and runs the most consistent laps down the ttrack.

thats lean and puts a lot of heat on the exhaust valves. Would be best to richen it up slightly for safety.
