Myself Kevin and LD have all played with differant configurations re lpg feed.
Swapping injector blocks. Swapping fuel feed to injector block. Swapping pipes on the vap so the outlets feed the other bank. Etc.
Made no odds.
I think it's an enterpretation the data that's displayed arse backwards. (Although that does seem implausible )
Certainly its not a fueling issue directly.
Technically, it is, as the (petrol) ECU can see a particular bank (no more granular than that on an Omega) is running either rich or lean, and trims that bank appropriately.
As said, the reason I'd always put it down to the vap or pipe run is because I don't see this on the 3.0, that has a single outlet vap, and both banks are feed with the same length pipe. The trims on that are always within a couple of units of each other (scale is 0 to 255, rather than the -25% to +25% of the 3.2). The newer kits we got from Motogas overcame many of the issues we had previously, but were more tricky to set up if you recall (and the injectors are shite, but that's not your issue)
