additional things do NOT include an advancer and an emuulator. they are a must and a a standard with any EFI CNG kit. yeah u went for a lambda, i agree, it costs around 12k extra, but i m afraid to tell u dat in the long run its still gonna cause u trouble as many of my friends with the exact same setup in their vvti corollas are now repenting on their decision bro. u shud have gone for SIS kit, and its support is definitely available at all Suzuki authorized dealers are Liana also comes with a FF SIS kit. still, best of luck with ur installation.
