Ok I bought the 2012 Convert and at the dealer they installed a SE Super Tuner, V&H long shots, and a Heavy breather, that being said I have had the bike back at the dealer 3 times because it pops and cackles, when shifting or letting off the gas.....they said they called HD and was told that the V&H pipes do not have enough backpressure for the tuner ro be right.....does this make sense ?  I went from a PC on a SESG 2012 and it ran perfect without V&H pipes just Rush slipons...but everything else the same....was also told the dealer would give me my money back and install a PC but it would run the same....Are they BSing me   What say you all ?  Thanks for all input....

I have the 2011 with the same pipes and setup.  The problem is with the map they download for this specific setup.  The only fix I know of is to have a custom map done with a good dyno tuner.

     Obviously the dealer just used one of the canned maps that Harley has for the SEPST.  Harley only has maps that match up with the parts they produce and sell, so there is NO map for aftermarket parts like a V&H exhaust system.  Any dealer who sells a customer an aftermarket exhaust and SEPST, and loads one of those maps instead of explaining the need for a custom tune, is basically screwing the customer.

With some aftermarket pipes it may be nearly impossible to completely eliminate all popping under all conditions.  But a good tuner can come very close.  I'd suggest finding a fully qualified tuner (not that dealer obviously) and have him tune it correctly.

I ran my 2011 FLSTSE2 with Pro Pipe from V&H for over a year with the quiet baffle and custom tune... It crackeled on decell but did not pop...  Just changed to the standard baffle and a new tune and have less crackle and no pops....  Used the HD tuner and local HD to do the dyno tune both times.   Can't think that your long shots should be any different with a proper tune....

The Harley SE tuner is EPA regulated just like the new bikes.  You can not run a richer mixture outside the EPA guidelines, no tuning or tuner or canned map can make the mixture rich enough to eliminate the popping with the new SERT.  It's a big waste of money and time.

The popping will continue until you get a non EPA tuner like the Master Tune TTS that allows you to basically reprogram the ECM,  bypass the O2 sensors and run a richer mixture eliminating the popping with awesome performance and a cooler running bike.

He said SUPER TUNER not SERT, your comments are completely inaccurate.

The Super Tuner only has one downloadable "canned" map for these bikes and unless your bike (yours is not) is setup exactly the way the bike was that the map was created for it will not provide a good tune. The Super Tuner will work fine if you have it Dyno Tuned which was said earlier.

Steve, there are two different products offered by H-D.  The SESPT is like what you described, a street legal device that just downloads street legal maps from H-D and doesn't allow changes to closed loop operation.  But the product they sell to most folks is the SEPST (notice the slight difference, designed to fool folks I imagine).  The SEPST is not street legal and it allows changes throughout the operating range of the engine.  So your comment is only valid if a person actually bought the SESPT, not the SEPST.

SEPST = Screamin' Eagle Pro Super Tuner
SESPT = Screamin' Eagle Street Performance Tuner

Why did you change the AC, I thought that the stock is already "heavy breather"?

[Jasray]

Stock filter on the CVO ConV is not a "heavy breather". I went the K&N route, but other options are certainly available.

Still it is a high flow low profile AC , isn't it? That's the description I found in screaming eagle catalogue

The stock air cleaner on the Convertible is called the Ventilator, and yes it is a high flow air cleaner.  I have never seen real flow data that would tell me if the Heavy Breather actually flows more air than the Ventilator or not, but someone who tested the same bike on the dyno with both filters indicated the difference was negligible, with the Heavy Breather maybe good for one or two horsepower more at the most.  IMHO, most folks who change from a Ventilator to a Heavy Breather do so for aesthetics, not performance.

I have the V&H Pro Pipe with 110 performance kit. I am getting a Thunder Max unit when they are availible (should be end of the month).  My bike was growling and popping after the install, I waited till I had 200 or so miles on and took it back for other money spending parts to be put on and had them adjust it.  It still pops but not nearly as bad. hoping the T-max smooths it out some more but it's good now.

[RCFlyer]

I have a 124 cu in engine, highly modified and a ThunderMax Autotune.  Their support is excellent.  You can email them your fuel map and describe the symptoms and they'll send you back an updated map.  Mine took a few trys, but it runs great now.  I have V & H 2 into 1 and it never pops.
