Is there a list of posts which a noob should read in this thread to understand how to start out with autotune? I think I am ready to give it a try but this thread is a bit overwelming with all the info. I got a base tune from Fuel Moto just looking to run some sessions to tweak it a bit..

Autotune is pretty user friendly. Just follow the instructions in the DJ manual and make a few runs. If you have specific issues there are many here that can help.
Don't try to read the entire thread. Autotune only came out about Sept. 2012, so a lot of the info prior to that is dated and deals with PC based tuning using WinPV and Logtuner. You don't need that if you only plan to use Autotune.

Great Support from DJ
I'm surprised they haven't ditched LT altogether, but happy they haven't. Send them an email and see if they fixed your issue. They usually get right on issue corrections. I run the updates (hardware) because they sometimes add little gee wiz things like live idle adjustment. As far as software glitches you'd need to get with DJ or the vendor that sold it to you and see if they're even aware of it and are working on a fix.
That said, I've spoken by phone with DJ regarding this issue. At the time (several weeks ago), DJ was in the midst of getting the 2014 model tunes completed and they had all the techs pretty well tied up (in more ways than one) pressing to get that version out the door.
The laptop with the older WinPV (v.1180) works flawlessly with logtuner.
The other that I just automatically update (v.1369) does not play well with LogTuner... and there are others with the same issue.
I did just update the PV firmware; I'll do some tuning and see if that had any positive effects.
Like you, that LogTuner is still around is surprising; but according to DJ (last time I talked with them), LT will be around for the foreseeable future because, as you well know, there are just some finer tuning things that there is no way AT can handle, at least at this point.
Always appreciate your insights. Cheers...

A question about the VE table I haven't seen addressed yet??
The original tune from a 2014 trike with the twin cooled 103 motor uses the (TPS) Throttle Position, while a downloaded map from Dynajet for the Twin Cooled 103 uses the (MAP) Manifold Pressure.
Is one method better than the other? And, why would Harley use the TPS method?
Thanks in advance.....Jim

Either way this is a good discussion topic.

Just curious has anyone run their PV on their bike and watched the different gauges like head temps and other ones when completely stock.? Then added items like A/C and exhaust and then rechecked to compare.wonder if anything would be seen.

I think TP is better, but purely opinion. I always wondered what happened to tuning, on a MAP table, when max kPa is hit at say 55 OR 60% throttle position. Are the throttle positions above max kPa untunable? Versus, a throttle position map that lets one tune those cells. How would this affect how the timing table is tuned when max kPa is reached at 60% throttle on a MAP table? I haven't seen a 2014 cal so I don't know how the resolution is set up regarding MAP columns. Can you post a pic of the ve columns? I'm curious to see what the resolution is.
Either way this is a good discussion topic.

Another question. If I use the original tune with PV, is it going to use the MP or TP? Can I choose which one to use?
All the columns in the MAP table is set to 70.0
I tried to send the tune by PM but don't know if it worked. If not PM me your email address and I'll send you the tune.

Finally got to do a couple of auto tune runs before the rain came today.
Since fuelmoto didn't have a map for a 2014 trike, he said to use the original.
The auto tune screen comes up as TP & RPM. Confusing at first but on the second auto tune I think it is easier than MP based. You hold your TP, and as the RPM's climb, you fill the column with hits. Slow back down, hold a higher TP, etc till all columns are filled. The hard ones to fill are high RPM-low TP.
There is an extra setting in the map when you view it in WinPv to select TP vs MP but not in my earlier tunes for the 2013 CVO. Just the 2014 tune.
After the second tune the VE table was less than 2% in most of the cells and 9% in a few. One or two more runs will do it.

The easiest way to the high rpm / low tp cells is to wind it up to 5000 or so and back off the throttle a little. It will start hitting the cells to the left in the tp column at the higher rpms. Chances are that it's a wasted exercise though. You may never hit those cells during normal riding anyway. As said before, I always suggest that someone go out and just ride for an hour or so, logging data, and then sit down and see what your typical riding data looks like. By this I mean being able to see which cells you typically hit when you're out riding. Putt around, back roads, highway, and some strong roll ons, etc. Then when you tune just make sure you hit the cells one or two past what your typical ride data shows. I've even put blue painters tape, making a blocked area that I want to concentrate on, and fill in that block with as many hits as I can. Anything outside of the block that gets good hits is just gravy.
