Hi all, just a question about spark. I am planning an LPG conversion on my 1uz using a 500 cfm Gas Research carby and Megasquirt ecu using 4 holden commodore coils in wasted spark mode. Can anyone see and problems with this? I am just concerned about backfires. The standard coils and leads may not be up to it if I decide to FI it in the future. thanks.
