Now, with this system constantly tuning to a given AFR.........the tune is constantly changing to fit that days temps, altitude, and everything about your build.
That alone makes this system so much more better then the PCIIIusb, SERT, or the ever useless HD flash. If I didn't gain a bit of power by doing this, I will still be very happy with it............just knowing the AFR is right, no pinging, and the abiltity to change things makes it all worth it.

RE: First ride with DTT installed
Good to hear you like it so far Steve,I would never go back . It was nice that you were able to get one that already had some tuning in the sytem.
In some cases, you really have to make some radical changes to timing and A/Fdue to the build of the engine. Have 5k miles on since installing it and am a satisfied customer - Shooter64 hooked me up with mine.
The DTT does take a bit of set-up, but overall you can set just about every condition on the bike from idle enrichening, hot soaks, AFR, and definetely adjust timing to where there is no pinging. I have been playing with mine all summer ( I just like to tinker, could have left it alone after the first few tunes) by taking the A/F up in .2 increments to gain better mileage and then if I do hear a ping, backing off the timing at the throttle position it occurs by a few percent. What started off as a bike that was getting 33mpg and pinged is now one that if I am not WOT all the time gets about 42 mpg and no pinging. This with a pretty radical build. I am still figuring I can go a few more tenths and gain a few more miles per gallon. Beauty of it is, If I want to go back to a maximum power tune, I have the download from the TCFI where it was maxed and can just reload it into the system.

I'm surprised DTT doesn't have any on their web site. It sounds like a pretty good product....
I justneed to see some proof.
What is the warranty? I couldn't find anything on it.

RE: First ride with DTT installed
This is not all about HP, it is about rideability, tuning for easy starting, smooth running, MPG and peace of mind that if you make another change you will not need another $500 worth of dyno time to tune it in. Yes, it will also bring about a bit of HP and Tq if there is some left in the engine to be found, but that is not the main reason for running a DTT TCFII-II or T-Max AT

I wanted to dyno my bike before i did the 95" build tomorrow.... Work has been so busy I haven'thad a chance.... I really wanted to see the difference to the PCIII setup i had but.... oh well..... I'll do the build without the data and be happy with it.....

I already know what my bike will do on a given day, on a given dyno, on a given tune, with the PCIIIusb. But the next day, if the temps are different, if the barometric pressure is different, if the altitude is different...............that PCIIIusb tune is useless. Not to mention if you ever change your exhaust, air cleaner, cams, or anything about your bike...........that PCIIIusb tune is useless.
Now, with this system constantly tuning to a given AFR.........the tune is constantly changing to fit that days temps, altitude, and everything about your build.
That alone makes this system so much more better then the PCIIIusb, SERT, or the ever useless HD flash. If I didn't gain a bit of power by doing this, I will still be very happy with it............just knowing the AFR is right, no pinging, and the abiltity to change things makes it all worth it.

I haven't seen any data to reflect how much better the DTT is from it's competition. All of the claims I've read here make it sound like a really fine system. Manufacturersuse dyno info to substantiate their claims of improved performance in this industry. By omitting this info from their website, DTT leaves me wondering why. It's seems a pretty smart marketing toolif the data supports the product.You guys do some awesome work testing systems and reporting results and I do appreciate your efforts and investment. I just need to see some data before I buy into it.

Looking at a dyno graph you can see a bike that runs smooth and has nice AFR across the board.

A dyno sheet give the viewer a graphical representaion of how a particular bike performed on a particular day on a particular dyno with a particular dyno operator AT 100% WIDE OPEN THROTTLE.
That's great for gereral baseline info, bragging rights, and RACE vehicles.
My bike runs like a batoutahell and I have a pretty dyno sheet that shows it makes more than 105ft/flbs of torqe @ 2500RPMs and peaks at 113/111, but those are WFO numbers. THey mean nothing about day to day rideability or how it's gonna do on my next 5000 mile vacation ride. For the record, it has great rideability too. In fact, the basic rideability and part-throttle response (transition) is MUCH better with the DTT than it was with a PCIII.
I don't know about the rest of you guys, but I spend VERY LITTLE time at WFO.... not even on my Buell. I may be the exception, but I doubt it.
Having said all that.... I totally appreciate and respect your views as well.
I will put it backon the dyno one day and when I do, I will most certainly post the results.
I like mine and that's all that really matters.

RE: First ride with DTT installed
I agree with PHILM in my case what I am looking for is knowing that even with just different slip-ons and a/c kit if thats allI did that I am getting the best "performance" I can get when I'm cruiseing. 90% of my riding is with the wife between 40-80mph. So all I want is the best I can achieve for situations like passing vechiles, mpg and long range cruising. I could care less about high hp numbers and high tq because at this point I am not building up for that. Give me a totally safe everyday rider that I can gas and go, as long as it runs at it's best possible peformance at any given time thats what I want. And I'd bet in the long run for long range riders thats what most will want.
From what I have learned already it appears the PCIII seems to tweaky to weather conditions for a given day, so what good is that if your riding out West and ride from deserts to mountains in a given day. It would drive me insane if the bike ran like crap because I installed a tuner that couldn't handle the climate changes like that. Now I just need to comvince myself to spend the money, it's looks like an awesome piece, actually if I could find someplace here in Wi close by that could assit in the install i think it would be going in this winter.

RE: First ride with DTT installed
I just had a dyno tune by Jamie at Fuel Moto and I am very happy with the results, both in rideability and the numbers. I am doing a 95" build this winter and am curious about the DTT. From my quick look at the DTT website, it appears you drill holes in the exhaust headers and weld nuts on to accomodate the oxygen sensors (I have an '06 RKC). Is this true?
