hi all,
today i pulled a tune from an Adventra (our aussie 4wd commodore) after complaints of pinging. I connected scanner and logged away only to find that spark advance was increasing at a alarming rate during pulls above 75% throttle. you can see at 10min:12sec the advance going up as the revs do. sorry for such a long log.
I have searched through the tune file without finding anything stand out.
Vehicle is 2005 auto VZ LS1 with extractors and standard intake. during this log no audible detonation was present.matt vz adventra.hplmatt vz adventra mod.hpt
have i missed looking over anything?

thanks in advance
