Very interested in following this! Thumbs up to T Vago!

I've got a 92 Dodge Dakota that needs monitoring, and it has the Chrysler constant pressure setup. I want to build a custom MPGuino with fuel pressure monitoring.

An added wrinkle... this truck also runs on wood. I start on gasoline and switch over gradually. So to shut off the gasoline I reduce the fuel pump voltage to lean out the mixture as I transition to woodgas. This lowers the fuel pressure and leans the mix, while I simultaneously ramp up the woodgas. Eventually I reach 0 pressure and no gasoline, although the injectors still fire. A stock MPGuino would be way thrown off by this. But if it could compensate for the pressure...

T Vago, will the code be able to reduce the fuel usage to zero at no pressure? That would be awesome.
