I am going to get my PV hooked up, and show you what they sent for mine.

Hopefully, you can learn me! I am not super happy, and need to find a dyno tuner that can accomplish something with this cam upgrade.

I am still dicking with exhaust, and have a new baffle coming Monday. I am going to put 300 miles on tomorrow, though.

I will be following your progress. Best of luck, brother.

 

just saw this... at your spend... you are more than half way there

 

I used the PV with a canned tune from Jamie @ Fuel Moto on my Low Rider S with the Bassani Road Rage pipes. Initially with the Fuel Moto tune there was some deceleration popping when decelerating through about 40-50 mph. I did 3 auto tune sessions (1 hour rides with city, freeway, and highway). My bike runs GREAT! no deceleration popping, great pull through the entire power band. I know the Auto tune isnt known to correct enough parameters to stop the deceleration popping, BUT MINE DID.

I dont feel a whole lot of improvement over stock performance, but it DOES run at least as good as it did with factory exhaust and tune. I would like to get her up on a dyno someday to see for sure if the new exhaust and tune helped, but for now, I am happy. It sounds great, and according to my "seat of the pants" feeling, it runs great.

Just thought I would share my experience since we have the same bike.

 

That is good to know. I am going to try the AutoTune tomorrow. Heading up and around your neck of the woods!

 

Well that's not so great I don't think? You got rid of the cat and installed a good 2:1 pipe, I would hope you would see real gains, "not just good"

Hell, I think mine is probably just as good, but I'm expecting noticible better...

When I put the Supertrapp and had the dyno tune done on my '15 FXDL I had a noticible improvement across the board.

 

So Izzy, would you say I should apply the AFR mods you suggested the other day to the now stock AFR table they put on it, leaving the new VE tables?

Also, what's the difference between MAP VE and TPS MAP tables? They only changed TPS MAPs btw. Thanks.

 

Yeah... its really not ideal. I know. I was expecting noticeable gains. BUT, I may have more power and just not notice it.

 

****, I can't even show you what I have...

 

I can't tell you what to do, only because you have to decide really (not to be coy about it)..I'll tell you what I would do, and I wouldn't trust that map for ****. So if it were my bike, I would go reset the map back to stock and re-apply the AFR mods until I figured out a more long term solution. Doesn't mean I'm right and they're not.. but I would have enough that I just wouldn't trust it.

Again, something you may want to consider looking at is the wide band auto tune kit, which I mentioned in another post.


To answer your question about what changing the VE does, I'm going to quote from a page here, as he does it better:

http://www.drdyno.com/AIM_2010-09.html

"You may hear some tuners talk about volumetric efficiency (VE). They may even claim to tune by VE, saying it’s somehow superior to the “old” AFR tuning. Turns out, you don’t have to know anything about VE to properly tune a bike. VE is not nearly as complicated as it may seem. VE is the actual airflow through an engine expressed as a percentage (efficiency) of the flow computed from the engine’s displacement (volume). By displacement, we are referring to its size, like 95". Sometimes the word metric is added to make it sound more impressive, I guess. In actual H-D engines, VE can vary from nearly 50 percent to over 100 percent, depending on rpm, cam profiles, and exhaust system efficiency. Using one of the ECM programmers brings up the VE tables. Adjusting their percentages doesn’t change the actual airflow through the engine or its VE, but it does cause the ECM to add or remove fuel. It’s similar to changing the engine displacement or injector size numbers to fool the ECM into changing fuel delivery when the overall maps are too rich or lean. So, whether done indirectly with VE tables or directly by percentage of fuel as with a Power Commander, the result is the same: the tuner gets to dial in the air/fuel ratios he wants. A side benefit of VE tuning is the resulting table gives a good indication of how the exhaust system is working with the cams. Good tuners can use that info to their advantage and tune the pipes for more low and midrange torque, but that requires retuning VE again. And, in my opinion, really good tuners don’t need VE tables to properly tune exhaust systems."
