Save money on that canned map
You will end up paying for a download that's still gonna be running lean. I, too, ended up getting a SERT after paying for a couple of different downloads.
Some 'stealers' will actually have someone that knows how to dyno tune the SERT. After the 'stage one' re-map, my bike was still backfiring thru the throttle body and just generally running sh*tty. Of course the selling dealer will tell you 'That's how a Harley runs' (Hehehehe) My scoot was running so lean, while out in Co. at upper elevations the motor sounded like someone had a handful of marbles and were shaking them. Start out with a SERT and save yourself the frustration. The SERT will correct a lot problems such as intermittent 'high idle', and all the coughing and kicking back thru the throttle body. It also dropped the temp of my oil 20 degrees. Well worth the money.

Hawgwash,
The SERT, or Screamin' Eagle Race Tuner is a computer program with a serial port module interface so you can reprogram your bike's ECM (electronic control module), with your computer. I had the Stage 1 download from the dealer, which has very lean settings, and bike ran not so great. I then bought a DFO (digital fuel optimizer), and it worked pretty good, but it couldn't get the ping out of light throttle roll-on. Now I have a SERT, which allows you to change the EFI air/fuel and spark parameter tables to correct the air/fuel ratio by RPM and MAP, as needed. The SERT allowed me to correct the ping, change the engine idle, and adjust the rev limiter. This is the only customer product that can reprogram the ECM. The other popular products, DFO and PClll(Power Commander) alter the electronic pulse waves from the current ECM download to the injectors. You can save yourself some money if you get the SERT right off the bat, find a dyno tuner who uses the SERT, and have him dial your bike's EFI system with the SERT on the dyno. Plus the SERT is always there to correct the air/fuel ratio if you change engine components over to hi-performance parts. There is a great "sticky" in the Engine Mods section by the famous "Springer" which explains how to get started with the SERT. Hope this helps you.

EFI Module
I'm a bit confused. My FLHTCUSE runs lean. It occasionally sputters and often dies. The dealer thinks this is no big deal and I should just get used to riding a Harley, because that's the way they act. This is my third fuel injected Harley and neither of the other two ever acted like this one. I was told there is nothing they can do, just live with it. Sorry, but for $32k the bike needs to run right when I pick it up, not after I spend another few hundred dollars on additional equipment that will void the warranty.

Doesn't sound normal. Is your bike completely stock, or have you changed the air cleaner and exhaust? Does you bike sputter and quit when it's at operating temp, or when you first start it? Possible the dealer tech reprogrammed the ECM with the wrong download, or you have something starting to fail causing the engine to sputter and quit. I would take it back and speak with the Service Manager about the situation. Don't be an A-hole about it, but be certainly firm that you want something done, as the bike shouldn't sputter and quit while riding. Remind him this is a safety factor also. Let us know what they do for you. I had a simular situation, and the dealer is always too quick to say, "oh, that's normal for a H-D".

Until you install the SERT, it's gonna run terrible. Have it installed by an authorized dealer (not necessarily where the bike was bought) and the warranty won't be voided. My '03 Ultra was kicking back thru the throttle body, misfiring, dying and generally running sh*tty. SERT cured all of that and more. Make sure to have the SERT set up with a dynamometer.
F*ck the maps it comes with. My stock TC88 is at 79 hp. (I'd have to look up the paper work for the torque). 32,500 miles. Best addition to the bike I've ever made sides the Hogtunes.
Sert
If I wasn't paying HD for the SERT, and paying HD to install the SERT, I might not feel so bad about spending an additional $600 for my $32000 motorcycle run right. I guess I'm old fashioned. I expect the doggone thing to run right WITHOUT extra parts/work.

SERT Not Stock
The motorcycle costs $32k. It does not come with a SERT. It runs lean, causing it to sputter occasionally, often dying in the mniddle of intersections. In order to make the $32k bike run right, the overpaying customer must purchase the SERT for $400 and pay an additional $200 for the dyno.
I plan to push HD into correcting the problem without cost to me. Again, I expect the f**king thing to run right when I buy it! It's not as though I bought it from a shady guy down the street.

You are right, you paid the $32K(oh my God), and you should have a motorcycle that not only runs great, but when you get off of it, you should feel completely satisfied, emotionally drained, and your pants shouldn't be at your ankles. :xhere:

I'm having (somewhat) the same issue with my 06 SE Ultra. Don't know where you live but I live at 6000 feet (no I don't live in an airplane) and I've had mine sputter in the middle of an intersection (very unnerving). I have learned that the bike HAS to be fully warmed up before riding or it can (and has) die a block from the house and be a bitch to get re-started. Mine has no mods... just as it came out of the box. I wonder if it requires adjustment for running at this altitude. My 2000 FLHTC (carb) ran great and I seldom used the choke to start it. Of course I had re-jetted it too.Thequidg said:
I'd like to know what the stealer has to say about your issue and what (if any) the final resolution is. Please either post or PM me.
EPA Rules
The EPA rule in question has been in effect since 1079--they simply don't enforce it. Theoretically, the Feds can fine you up to $10k PER DAY for non-compliance. This isn't just on '06 models, it includes '79 models and up. I know of a couple of guys who had their warranties voided by HD in earlier years. The significance of this one is that they've made it mandatory for the dealership to void the warranty at the time of making the changes. Of course, that doesn't solve the sputtering issue.
As far as high altitude problems, the ECM should take care of that automatically. Of course, the stock map causes it to run lean to begin with, the altitude makes it even more lean.
