Very true!

Thanks again

 

You didn't mention if you bought the training disc for the SEST. If you didn't get it you might consider buying it. It will be very helpful if you are looking to avoid dyno tuning (which I think you really should consider somewhere down the road).

In the interim, the Smarttune feature will absolutely make a substantial improvement in whatever map you are using. Download the closest map to the bike and then you can use your laptop, the SEST software, the SEST memory key and Smarttune to set the key into record mode.

You will then want to record as much of a ride as possible (about 45-60 minutes). Once you are back to home you can download the recorded data into the SEST software and then use the Smarttune feature to analyze the recording and update the map. Once the map has been upgraded you can save this new map to the bike.

It's a great feature that I've used to make over 30 tuning runs to make improvements to bike's performance. In all cases the Smarttune recommendations will make a positive difference in the performance. Sometimes the difference is modest, sometimes its substantial. It really depends on the kind of ride you recorded for use by Smarttune.

You'll definitely want to get the training disc and spend some time on the computer to better understand how to make recordings, save them to your computer, use the software to analyze and make map changes and then save the updated map back to the bike.

It's not difficult, but it does take some time to learn. I'm very glad I have the ability to make these types of improvements without running to the dealer. Definitely a great feature but to be honest its not a replacement for a dyno tune by a very experienced tuner. It's a great way to fine tune the work of a tuner or to improve an already good performing map that needs to be modified because of a new exhaust or A/C etc.

BTW, the SEST software includes many maps includings various maps for a 103 with different cams and different exhaust. Read the descriptions for the 103 maps and start with the one that's closest to your bike's setup before starting your Smarttune recordings and upgrades.

 

Thanks Heatwave!! Actually just got the training DVD but haven't had a chance to watch it yet. The map that's on my bike was put there by the dealer as the "closest one" they could find (I believe it's the one Hog-Doc suggested I start with).

I'm curious about your comment that the SEST Smartune might improve over a dealer dyno tune. If this was the case it would seem that the Smartune might be a good substitute for a dyno tune. My guess is that a good dyno tune will always be better because additional sensors are used versus the somewhat limited O2 sensors that are built into the bike. Yes? No? Maybe?

 

Good question, how does it work without wide band sensors ?

 

Think of it this way....Smarttune "polishes the edges" of the map for smoother throttle responses, less hiccups during throttle rolls-on and can make the low end performance come on stronger VS. the base map it starts with.

The real question is how good the base map is that Smarttune is working with. The stronger the base map is to the max performance capability of the engine, the better the fine tuning results will be.

A good dyno tuner is going to get the map much closer to the actual needs of your engine than one of the stock maps that is not necessarily a "perfect match" for your components. Smarttune with then be able to modify the map based on recordings taken of the engine's performance for as many miles as you wish to record.

Smarttune only makes map changes to the VE tables and therefore does not take into consideration timing adjustments, injector size and the many other tuning parameters within the SEST. Therefore to get the base map close to peak performance, it takes an experienced tuner to make these other adjustments (plus adjustments to the VE tables as well).

Once the map is really close to peak performance, Smarttune can take advantage of many miles of performance recordings to make final adjustments that would have taken many hours on the dyno for a tech to gather and use. The computer and the software can accelerate that process by taking advantage of the data that can be collected while you are out enjoying time on the bike versus building up miles upon miles on a dyno by the tech. Which way would you rather build up miles on your bike?

Either way, Smarttune will only incrementally improve the performance from the level it starts with. The better the map is that it starts with the better the end result will be.

In the end, if you like the performance of the bike with a stock map from within the SEST, you'll love the performance after a handful of 20+ min recordings are used by Smarttune to make improvements.

If you're smiling from ear to ear after pro dyno tuning, then you'll wet yourself after some Smarttune updates.

If you're starting with a map that is only "so so" in terms of the smoothness of performance, than Smarttune is only liking to make you feel slightly better about the map than before you Smarttuned it.

 

OK Boys. What does the SEST cost? Where do I buy the SEST? What all do I buy? Best Price? Best service? Part No. for 09 Ultra? Thanks

Did a search on the HD site for both SEST and SERT and got NADA

 

lets start with i tought that way to now i bought the sert cables and played last saturday i was in daytona new power commander 5 and dyno tuned so play a little more i figure i spend a little over 1000.00 playing to get what i really needed but now iam happy 97 hp
spend it now or later learn by my mistakes
thanks gabe

 

Get the tuner from chicago hd. I got mine there for around 370. then you have to buy the cables also. you can google screaming eagle parts catalog and download the pdf catalog. the part number and almost everything SE will be in that catalog.

All this tuner stuff is entirely too expensive but what the heck - it's a hobby right? My OL always said I needed a hobby ;-)
