The biggest improvement in fuel economy I found was by setting the DFCO parameters to be a bit more agressive.
i,ll give it a try thanks
If you have lean cruise active , you can play around with lowering the enable and disable speeds and log AFRs when active and alter Lean cruise target AFR table to get desired AFRs
or if not useing lean cruise - log and identify your light throttle cruise cells and command leaner values in these cells in B3647. I have mine at 15.5 in the 1600 & 2000 rpm rows up to 45 kpa and 15.0 in the surounding cells , made a huge difference to economy at cruise on mine.
Cheers

using lean cruise at present.just cant seem to get any better than 12.5 per hundred k's.unless i slow down to around 90 kliks comes down to10.5-11 per hundred (by the holden thing in the dash)i think its accurate.
