I suggested you call him since he sells both and won't BS you. It sounds like you're on the right track for your needs, so let us know how it works out. Next time I talk to him I'll need to ask how the TTS is tuned without a dyno tune. Does he provide a canned map?

 

It doesn't tune itself but uses 3 programs to get the tune for your bike and the way its setup. TTS comes with maps for different bike/ motor setups, there is a file that tells what the different maps cover. I believe their web site has the instructions for download so that you can see the process to get the tune. Not hard to do plus you get to ride the bike to get the data for the tune.

 

I just don't think you can tune WOT. As long as you are inside the small range of the factory O2 sensors you are good...outside of that not so much...just a guessing game basically from what I've come to understand.

Maybe someone else with true TTS experience could answer it....although I suspect that many users don't even know what we're talking about.

 

Just curious, unless you're drag racing why the need for WOT tuning? You're not going to operate in that range. When doing my riding/tuning for TTS, I got on it getting on the highway, 4K rpm and the data showed maybe 80 TPS. Haven't been there since and at 80 mph and just over 3K rpm there's plenty of data for a tune. Why beat the engine at 100 TPS and 6K+ rpm unless drag racing.

 

that's you...other people are different. Do you ever pass a car or have a need to accelerate very fast?

 

The WOT throttle is not totally untuned when using Mastertune. When you smooth out your VE tables you carry the last cell learned to the higher load and it should be close enough for passing that 18 wheeler, lol. In some cases, you can see a pattern developging and can interpolate out in the VE tables to the 100 KPH column.

I've got a lot more acceleration now than I did with the PCIII.

 

Iclick, the way you like to work on your bike you would love the TTS. You don't need a canned map, you select one for to your bike and tune from there. The amount of areas to adjust your bike are greater than sert or sest. Comparing data that you log to the "vtune" map you create calculates new ve's. Vtune data is only one of 6 types of data you can record. Even the heat management cycles both cylinders, not just the rear.

 

I have recently purchased a tts, and now can post my tuning experience, and maybe it will help other forum members. I have used many different tuners (PC111, Terminal Velocity, Fuelpak, etc.) with several bikes, and have to say the tts has mine running better than any has in the past. I don't notice the difference with top end performance, but with overall smoothness, throttle crispness, fuel mileage and overall driveability.
When I put in a Andrews 26 cam I lost fuel mileage, it ran hotter, and, although the performance was improved, it didn't run as smooth. I purchased the tts and self tuned the ve tables; chose a afr map more geared towards a cooler running motor than fuel mileage (taken from a similar build); and also chose a spark advance table from a somewhat similar cam. I now have a great running, cooler running bike that is getting mileage as good or better than before the cam swap. I could work harder at fine tuning these maps, like a dyno-tuning session would do, but I don't think it is necessary, at least for me. The time and effort needed to reach that last 2% of efficiency and performance I dont find to be worth it presently, but others may feel differently.
Now to ask which tuner is better, which is how this thread started, I think depends more on the person using it. A tts is not a plug it in and walk away tuner like a fuelpak or a power commander with a pre-loaded map. If this is all you are willing to put forth in effort, then I suggest you stay away from the tts. On the other hand, I am by no means beyond average knowledge on the subject of fuel injection; yet I was able to school myself through HD forum threads and the TTS website, and get a very favorable result. Even though it may look overwheming to begin with, I didn't find the knowledge curve to be all that tough. I had a good understanding of what to do by the time I got the tts, and I had a final tune within a week of my spare time.
It seems that a good share of the forum members are hands on with their bikes, as I am, and I am confident that they would find the tts to be a great tuner. You are in control 100% of the ecm funtions that determine how the engine runs. What is there not to like about that? You may need help at times, but if you have a problem, it can always be corrected. And there is another small benefit that I found useful. You can correct your speedometer readings! My GPS proved the speedo to be off by 4% or so, but not any more.

 

Just got back from a weekend trip. My bike with 3-5 starts per tank running a mixture of country back roads 35-55 MPR and freeway speeds between 65-85. 40.8 MPG. Love my TTS. The outside air temp was upper 70's to low 80's. The bike oil temp only once climbed above 180 deg. I'm thinking about changing my CLB and retune. Maybe I can get a little better MPG with only a small temp increase.

 

Well said
