Can I tune out EVAP without physically removing system?
I was wondering if it's possible to tune out EVAP from the PCM using Tunercat, and unplug the solenoid on the side of the intake, but still have the system physically in the car. Will this hurt anything, the Code 26 that I am getting is driving me nuts.
I have done a search, but can't seem to find the answer to this question.

Good, please for the safety of everyone try to keep your evap system working, and working properly.

Not advisable. the evap system is one system you really should keep intact for your own safety. You are talking about taking a system that controls gas vapors (highly explosive, liquid gas is actually not very volatile at all only in vapor form does it become explosive) and turning it off without replacing it with anything to control those vapors. That is a dangerous situation and one you really do not want to be in.

Nice change of subject.

Evaporative control systems have been required in the US for about 35 years. In many parts of the world they aren't required today. It would be _safer_ to have no evap control system, venting the gases to the atmosphere as we did for many decades.
Please provide evidence to support your claim that removing the evap system causes a dangerous situation.

C'mon, you can do it. Stay with your claim and provide some evidence that shows that you're not just talking out of your ***. Should be easy enough.
I mean, it's not just dangerous to the guy who removes it, it's dangerous to everyone. We know that because we read it on an internet forum somewhere:
A clear danger to self and others such as this will provide millions of hits with a quick Google search. Let's see a couple.
Not that it wouldn't be cool if it did work that way. Self-immolation as punishment for emissions tampering...

You're really reaching on this one, to defend what is basically an indefensible position. Those examples are ridiculous, and in no way related to a small amount of HC vapor flowing out of the fuel tank of an automobile as it "breathes".
Welding on a tank..... pouring gasoline into the basement of a house.... one of the Gulf Coast's largest refineries? Why didn't you throw in all that nasty jet fuel that exploded when someone flew a couple of planes into the World Trade Center?
The EVAP system is there to prevent HC vapor from escaping and polluting the atmosphere, not to reduce the possibility of an explosion. Yes, gasoline burns, but only when the concentration of the HC's in air is within the flamability limits of the HC/air mixture. A very "lean" mixture of fuel and air will not ignite, because its outside the limits of flamability.
Get a grip
The 12,500-litre tank exploded as workers were welding its lid at the same time as another worker mistakenly pumped gasoline into the tank, thinking that it was water.....
The explosion and subsequent blaze, believed caused by a buildup of fumes from gasoline poured in the basement of the house
Major events related to the 2005 explosion at BP's Texas City refinery

The gas vapor control systems are in place on the car for a reason. Before we had modern fuel system designs explosions were a major problem. The EVAC system is part of a larger system designed to control gasoline and prevent it from igniting outside the combustion chamber.
