Can't see any lpg injectors in your pictures, where are they?
The 5th pic down (just before the tank pic) shows the driver side of the inlet manifold, the individual injectors are installed directly onto each of the manifold's port runners, except they're not in the pic because I hadn't fitted them when I took the pic! Normally you won't see them because they are below the charge coolers and air filters but with the engine cover off you can see the 4 gas distributor blocks that feed the injectors.
Did you have remove the inlet manifolds?
Didn't have to but did.
Did you have to set it up as 2 different systems but try to end up with the same readings?
Should always end up with the same readings. Only really need to calibrate one side, then copy the config file to the other ECU and see how that bank behaves. If there were any more than very marginal difference in how the 2 banks behaved with the same config file then it would be likely the setup/config was wrong in some way... Then set one ECU as master and one as slave, then see how the engine behaves when both sides are switched to gas.
