A while back (few weeks) there was information floating around about the new Vtune3 that may or may not include spark tune. Has anyone heard of any updates on this much needed feature?
Steve are ya there?

I'm curious on where this is in the release phase as well.  I'm pretty sure I've seen it, on Steve's personal computer, while I was in Cinci earlier this year.

I seen it there too.  Correct me if I am wrong but it will just show areas to take away timing not add correct?  Same idea as what sepst and PV does correct.

Works different than SEPST and PV.

SESPT does not do any spark correction and PV removes spark from the main spark tables anytime it shows pinging. Hot, Cold doesn't matter. Vtune3 works completely different and once it's ready for release we will talk about it more but not until then.

Thanks for the update Mr Cole
Now if I could have mine by last week I would be velly happy

I see spark correction through sepst all of the time. You prob. don't BC you don't use it that often but now I remember VT3 does it with different temp tables pretty cool raising the bar once more once it comes out.

You can see spark retard in the SESPT but as of the latest update (6.000.0006) it is not used for any correction to the calibration. It only corrects fuel and I believe we are all talking about what is being corrected for not what you can see.

I seen Vtune3 on the new brochures we just got with our last TTS order. I hauled ass to the dyno room, ran the updater and got nothing!

Buzzkill.

Hmm. When I run smart tune and the ve tables change then I jump to the timing table it has changes also, that I did not mess with.  Weird, must just be my computer that does this.

Not your computer Joe.....when you click on smart tune the parameters are set for you and one of those parameters set is retarding the timing 4 degrees, this is what your are seeing.

I am aware and have been aware of the -4 that sepst takes away for smart tune I am talking about after you use the smart tune file for the VE tables it will adjust those tables but if you jump over to the spark table you will sometimes see if it is needed timing taken away when it seen spark knock during the recording.  Spark correction dealing with head temp will be cool.  But spark correction on the main tables is not new in the world of harley tuners.

I have seen the SESPT change timing. I set up a timing table, download, upload and changed.  Usually in a way I don't want.

What this has to do with Vtune3? IDK.

Been doing battle with the spark advance tables for my 120R for a couple of weeks now, and still losing. I didn't know that Vtune 3 will help when it gets here. While working on the spark tables it occurred to me that it might be possible to adjust them in a way similar to the way the VE table VTune works.

Spark advance seems much more difficult to solve though because of the impact engine and intake air temperatures have on spark knock, as well as load on the engine. While working on my advance tables I found that sometimes the motor would ping in an rpm and MAP region that was previously "OK". The only conclusion I could come to was that the temperature (and who knows what else?) was having an adverse effect on spark advance tuning. But without some tool to adjust spark advance in relation to all the variables, it's very difficult to make the right adjustments. I think my table that subtracts timing based on engine temperature also needs some tweaking, but it's hard to factor that in to get the advance set correctly. I'm tuning without a dyno, and having a hard time getting rid of pinging, but still trying to keep a reasonable amount of spark advance...

In the end, all I have been able to do is to take timing out in broad swaths in order to get rid of the pinging. I'm sure I'm giving up performance (and fuel mileage) as a result, but I can't afford to damage my engine as a result of pinging/spark knock. If Vtune3 will help, I can't wait to see it!!!

When your recording spark tune data, and playing them back.  Pay attention to engine temp.  If you are always seeing that spark event at 160 and not at 144?  Take 2 away from spark temp correction table, rinse and repeat.  Might try blending that down.
