First things first, this is a lemons racer with no street registration; emissions regulations don't apply.
In order to clean up vacuum lines under the hood, I'd like to remove the charcoal canister and vent the gas tank to atmosphere. There's an electronically controlled valve on the canister that regulates when it's exposed to manifold vacuum. I'm guessing this is so the valve can stay closed when on boost to avoid pressuring the fuel tank. I assume the engine runs leaner when the valve opens since it sucks in mostly air (with unpredictable gas fumes, depending on temperature and atmospheric pressure), and that there's probably some sort of fuel compensation in the ecu.
What happens if I just pull the canister out? Does it periodically run rich? Is this valve-opening signal something I can disable altogether using t5suite, or if not can I at least turn off any corresponding fuel compensation?
