i use full offboard 100% propane (green bottle) with the ECU not having the ability to control anything (no solenoid used), but just for a test i took a fully bypassed installation (Tam F-18) that was setup for onboard PowerMax and after draining the onboard tank i simply hooked an offboard propane to the fill line, opened the regulator fully and initiated a start, she fired right up with no adjustments needed. while I'm sure there will be a few situations that require a small change or two I'd say for the most part you'll get a perfect start with no modifications needed.
