Default Meth and E questions

I am currently at 650 whp basically full bolt on. I want to run ethanol, but I know I will need meth as a fuel supplement. My question is, if I install a flexfuel sensor, how will the meth know how much to spray? The meth from my understanding is a stand alone system, so it's either spraying or not, correct? So lets say I fill up and the ethanol content is E40, how would it know to spray less than lets say full E85?

You will need a tune for sure and I would not try to do it alone. My meth kit is set up based on reading from the MAF. Others do if off MAP. Either way, work with a reputable shop/tuner to get it dialed in. I also have a low side fuel system to make sure there is enough high side pressure/fuel. You need more ethanol to get the power so you may need this if you are going to run full E85.
