removing LPG setup

I've been removing a lot of my defunct LPG kit today and have traced some wires back to a couple of control box/ ecu type things. Are these purely for the LPG side of things or is the one the ecu for the petrol side of things too?

They are mounted under the passenger seat, right where the jack is stored.

Right, i've found out the second one is the OBD2 emulator for the LPG kit so thats coming out.

Any ideas on the first one? Its not the best picture as it is 90 degrees out. If you flipped the picture 90 degrees clockwise its would be the right way up and it would be the part at the top of the picture (So at the moment its the part to the left of the picture )

All the controll boxes in the engine bay are bodged in lpg stuff.

You will need to untape the loom because the log kit breaks a few of the signal wires like the cam sensor and the injector commons. But it is all pretty obvious when you untape it.

Ok cheers Matt, i've untaped some of the loom so i'll carry on tracing the wires and ripping it all out, quite therapeutic lol
