You should probably take your car to a local shop and hope they don't turn you away for a tune.

but .. we for got one thing every Car no matter what is different.

You could have the same setup and one might run like crap one will run fine
its like saying every 1600cc injector flows the same .. my car idles good when im consistent at filling up at one specific pump when i change a gas stations car runs different cause the blend of 85 is different hence crap idle i have to change dead time to fix it ..

Why would you use deadtime to tune ethanol percent? Deadtime is to tune to your specific injector, not fuel type or blend; that's what injector size compensation is for (besides for actual injector size and base fuel pressure). If ethanol % really is messing up your tune, it will change it at WOT too, not just idle. Deadtime has the largest effect at the lowest IPW's.

If you use closed loop like stock (I don't, I run open loop all the time), then it shouldn't even matter anyways as the ECU will correct it.
