Dear bros
Friend after swopping in a bigger cc (same series) engine, would like to check what could be the possible causes for engine pinging sound during letting go of clutch. It's for a period of 2-3 secs. When flooring, no pinging under load. But pings again when reach >6k rpm.
Some suggested the timing's out. If so, will this be resolved by unichip tuning?
Else, could there be any other possible causes and remedy? Please advise. Thanks in advance.

Re: Pinging after engine swop

==> yes, asian car tends to run rich but that doesn't mean the brain knows how to manage the new setup... anyway, bad assumption for that...Kheong wrote:Thought they say asian stock cars are on rich side, so when higher cc, may even out to be just right. Cause asked some ws, they claimed that they have not encounter pinging issue with this setup, but they also agree with you that piggyback should be able to solve this issue.
get a piggyback to get it tuned properly should be alright liao.
