No other way around it so far...

There is surely better ways and your tuner should know this:
The circuit is seeking a resistor on the line. My failsafe method utilizes a relay and unless wired right, this causes this code and it tells me when my failsafe for my meth kit has activated, it happens anytime here is a break in the wires to my ebcs, which my setup does by design.
My car setup does this by design with my methanol injection kit, the solution is to place a resistor in lieu of the evap valve load (which is what the ecu is expecting on these wires whether you run a factory rom or ecutek)or the ebcs solenoid i use has the same exact load, both identical, if your ebcs is different that mine this may not apply, I run a Perrin pro unit.so...
My tuner and I decided it was smarter to leave the code enabled so I could know if there was a problem with my failsafe setup
... a dpdt relay is all the meth kit uses for this so you could rig it up if your tuner know how to use relays
I'm not a fan of perm disable of codes unless there is no other way, its a Less than ideal thing for a tuner to go disable all your codes and then when you have a problem, you're hunting in the dark!
Hope this helps
Curious what ebcs is causing this?
