Advancing ignition timing on a 99 Prelude
I have a friend of mine who owns a '99 Prelude (VTEC). We've been trying to advance the ignition timing but everything we do doesn't work. We have looked for any info on how to do it and found out that you have to jump the service connector to do it. We did that too and nothing happened. Anybody have any clues on how to do this?
The only guy that I know that has advanced his ignition timing has a 94 (ODBI) integra. Also I asked my mechanic about advancing it, and he said leave it alone, its fine from the factory. I even further inquired adjusting it b/c of the high elevation (I live in CO) and he still said don't **** with it.
