Re: Any EFI Live users on here?

Forums are once again your best bet. Most folks who tune at a high level don't really like to "give away" techniques (at least not anything advanced), since its usually their job. My tuner and I have a verbal NDA against posting my tune for that very reason.

I get that they want to protect what they might view as IP..however, IMO that attitude shouldn't apply to just explaining things like deleting emissions, understanding the interface etc.

Random things I've learned from various tuners;
Save obsessively. Make a few small changes, SAVE.

Fuel and spark graphs should be smooth. Viewing your hi/lo spark tables etc should show smooth curves and rounded edges. Sudden cliffs or spikes indicate an anomaly or error. Take the time to smooth these out!

Don't just throw fuel and timing at it. 27-30* is all most of these need, with 32* being "high" *this is veeeery general...but just don't throw 38* and think it'll be happy.

Make sure you have a wideband either in the logging, or handy to view. Learning to use it helps you no matter what your goal.
