Ahhh ...

Well, basically, the progressive stuff is actually even more complicated than single shot stuff (and more dangerous without some sort of feedback). It's the same principle as the alky progressive systems, you PWM a solenoid (or solenoids) to control amount and do it based on a window switch (for RPM).

The one we built was more comprehensive and actually talked on the CAN bus (only worked on 2004+ CAN vehicles). We used engine sensor data (and hence there wasn't a bunch of external wiring and such ... just the solenoids to an underhood module that provided enough power to run them and talked on the CAN bus to the head unit.

Worked pretty well and was almost like supercharger in a bottle. The biggest thing was calibrating the PWM for the jets/motor to avoid going lean during less than WOT.

Just too prone to user error and misuse ...
