yeah, there are a few of us running the DTT.... TMAX added timing.... thats good cause they was having issues without it.......
DTT has had that and like has been said.... if your just staying mild Tmax is the way.... but if more then DTT.....
I have the DTT on my TC88 (soon to be HQ 95") just to be able to play with it and I was tired of the PCIII lag. I have actually created an installation guide to help others install it.... Just PM me with and email and I can send it over.... Remember its a guide......

 

Good responses from both glens & spike.....

Regarding the timing adjustment on the TMax.... I believe that degree of tuneability has always been there ~ it is just limited.

As I understand the TMax (which is admittedly limited), you can adjust timing "by RPM" - which is visible in the screenshot above. On the DTT, it's "multi-dimensional", in that timing is adjustable byRPM @ a given MAP (manifold absolute pressure) value. The result is tunability via RPM & engine "load".

For comparison sake, here's a shot of the DTT timing granularity. THese values are applied to both front & rear cylinders but they can be offset by as much as +/- 5 degress.

I recently ordered a DTT from Bart for my 07 SG, looking forward to it, but I have to admit, I'm a little nervous whether or not I'll be able to figure it out and get it running good.

 

The DTT for the 07 bikes has an auto-tune mode....

I`m looking to buy a DTT for my 07 SG too......Who is Bart and how do I contact him to purchase mine... Thanks

 

Ok DR and Fly
Make sure you understand that BOTH units only autotune AFR and NOT timing. Timing is adjusted manually.
Like is said above I have an install guide i have created and it will help you understand the install. Download the install guide from DTT and read it over and PM me with your email and I will send you my guide to make things clear.

 

Bart is "Shooter64" here on the forum. Send him a PM and tell him you are looking for one. He'll take care of ya!

His website is: www.cateyecustoms.com

The document Spike put together is excellent and would be very valuable during installation & setup. THere are several of us here that have had great luck with these units ~ espically those (dunno who) that are constantly f'ing with things on their engine....

 

Hmm... I was under the impression that both the TMax and DTT were bothbased on the dated Alpha-N technology that manipulates the AFR via RPM/TPS. I apologize for any misleading. So the DTT is a Speed Density Alpha-N system? Remind me again why the DTT would be a better option than the SERT for this type of tuning in the hands of a qualified dynotuner. Don't you have to manaully set the TPS signalvoltage and setting on the DTT sometimes requiring modification?

Fill me in on the ease of Plug-n-play between any of these units. Thanks, obviously I'm clueless but willing to learn

 

Me Too...!

 

Darren....

If a guy has a build and does not jack with things, AND has access to a GOOD SERT tuner, then that is a great option. Furthermore, if you add a DTT TwinScan II+ to your toolbox, you can tweak it yourself as you make mods.

At the time I purchased, installed, and learned about the DTT, I had never met anyone that I consider a GOOD SERT tuner. Since that time, I have met someone that fits that requirement... in fact, he's much better than GOOD... He's AWESOME... For the curious, it's Pirateeye here on HDF (KevinB)... After numerous conversations, and some face to face time, etc.... I have a much greater respect for the SERT as a tuning device.

Having said all that, I still prefer the DTT.... "For me", it is exactly what an ignition/tuner should be, and will be even better with the addition of dynamic timing adjustment. That will come with what I've heardwill be calledthe TCFI-III.

Yes, you do have to calibrate the TPS with the IAC. In fact, you sometimes have to tweak the TPS for a "proper" SERT tune too - I learned that from Kevin.

As far as ease of use.... I don;t think I've ever had much to say about that. I can say that the DTT does take some patience, common sensse, and the ability to read in order to get it setup initially. Once it's set up..... You can pretty much just ride. I have not had a chance to play with a TMax yet, although I have been talking w/ KDeitz about his quite a bit. I would love to get to play with one so I can make an informed comparison between the DTT & TMax, but at this point I have experience with only opne of them. There are plenty of us on the forum that have install one (DTT)or many and can certainly help ya get properly setup.

As far as SERT tuning goes... I would recommend Kevin (Pirateeye) to anyone, regardless of the build or bike. He's awesome. He is in the Atlanta area, but if I had a SERT, I would be taking a ride from Dallas, TX to Atlanta, GA in a heartbeat to get the best tune I could. I would do it in a heartbeat. To me, getting my bike to someone I consider truely qualified more than justifies the cost and time of the trip.

In the end... all three (DTT, TMax, SERT) have their place and all three are fine system that, when properly setup, will give you what you want/need.

 

I was just this morning poring through the info at Daytona-Twintec.com and they are definitely Alpha-N. They specifically tout the fact that it's the better method at idle and low-rpm for wilder-than-stock cams. They also make many references in their guides to "3D maps" but I think they were referring more to presentation in their computer software than to the ECU actually using 3D mapping. Still a little unclear on that...
