How does Jay's "Propain" work?

[S10xGN]

How exactly does the Propain setup work? At what point (boost) does is start injecting and where does it get injected? Does the ECM pull fuel to maintain AFR and if so, based on what? What can the user control with the "brain" that comes with the kit?

TIA!

It comes on just like alcohol at a certain boost level.

The advantage is it can come on at a much lower boost level and not bog the engine.

No the ECM does not pull fuel, the additional boost makes up for the additional fuel

You can control the pulse width of the solenoid to vary propane delivery, the cut on point boost wise and the control unit also has an overboost alarm which you can set for your max boost. If you go over it, a warning light comes on.

Some of the guys are turning the system on as low as 7 PSI.
