TTS Mastertune

[sz0wxc]

so is this product out.. I am taking my bike in this weekend for the 95 upgrade and cams but I would like to pull the map I currently have and see what the new map they install does or how it is different.
With this product can the dealer use the old sert software to update my bike with this interface? or would they have to use the new software?

[blkfalc4]

Should be able to use the older mt6 files of the sert.
Heard mastertune should be available to dealers approx 7-30
But maybe some others here have more info

Steve,
I really appreciate all of you knowlegeable posts for us..

Question.
will the system still be able to read the DTC's and will you be able to reset the DTC's

I would asssume so but thought to make sure


thanks

[Steve Cole]

All orders have now been shipped to the dealers. They should arrive end of this week first of next week to the dealers depending on how far away they are from us. We are now starting to build inventory so orders can be processed and shipped quickly.

In DataMaster you can read and reset all DTC's

Now that the Product is out when are you going to do the SERT upgrade ? and what is the price for that

[Steve Cole]

I do not know a time line just yet. I figured I pushed hard enough to give them a few days before I start in on them again about the update for the SERT units. I hope I will be able to give an answer over the next few weeks.

Steve,,,

as usuall we want it all and we want it now...glad to see that it is finally out there been a long wait..

another question for you..

From what I have read so far it looks like the Master tune will still be using the narrow band O2 sensors..
any plans to go to the wide band sensors in the future?


and since I am one of those that is currently using a different system DTTIII and to hook up my SERT for the process that you described to have it updated,, is there a way to have the upgrade done without that process..

where on the tts sight can i download the program so that i can see the maps????

[Steve Cole]

Let's first get people to understand sensors and there names. The factory bikes use a switching sensors not a narrow band. Most of your aftermarket kits use a narrow band sensor. A true wide band sensor runs about $900.00 per sensor plus the electronics to run it. So with that said the technology we developed was based on a switching sensor, so I do not see us doing a narrow band or wide band sensor anytime soon, but you never know.

The upgrade procedure is already thought out and will be the only way we can do it. What you’re going to have to do is get a new program from our web site and install it on your PC. Then take your SERT interface and cables out to the bike. Power up the bike but do not start it, then run the program you've installed. This will place a file on your PC that will need to be sent to us along with your interface. That's it on your part. We will then update you to the new software and interface to work with the new software.

As soon as they have the software completed for the upgrade process it will be posted on our we site.

Steve,
Thanks for the information..

I guess I was looking to see if the O2 sensor was going to be the heated or non heated sensor (amount of time running in the open loop mode..) but I guess it really doesnt make any difference in the long run..I apologize for not being really knowlegeable in the O2 sensor matter,, But from my understanding the sensor that HD uses has a very narrow (hence calling it a narrow band sensor) operating range, and the heated sensor that DTT uses has a broader range of operation (hence calling it a wide band sensor) for correction of the AF ..

The program that I am trying to find on your site is the base (I believe that it is the Master Tune program) program so that I can look at the maps you currently have listed.
I would like to look at some of them and see how your program works..
I had it at one point but have since had a system failure and had to replace the hard drive..

I am sure it is easy to find but for some reason it is eluding me at this point..
sorry about that...

again sorry if you have answered all these questions before and yes I have read all the posts here and at the Doof Clenas forum but cant find the answers..

thank you

To clarify what Steve is saying, all you have to do is look at the sensor output graphs: switching, narrowband/wideband.

Although, I don't agree that systems like the tmax and DTT are not using wideband sensors (if that is indeed what he's saying). They are. They may not be as accurate as the expensive ones, but they're still wideband sensors.

[Steve Cole]

The aftermarket systems use a narrow band sensor. They will not cover the range nor do they have the accuracy of a true wide band.

Switching sensor switch around a 14.68 AFR center point
Narrow Band sensor reads AFR from about 12:1 to 17:1 on gasoline fairly accurately
Wide Band sensor reads AFR from 0 - 25:1 very accurately

The narrow band sensors were developed for the auto industry to be a cheap sensor loosely based on wide band technology. Cost of a narrow band sensor $60.00, Cost of a wide band sensor $900.00. Now does anyone really think they do the same thing? So why would you call them the same thing.

[Sleeps In Trees]

Steve, any idea when the cables will be ready?

Yes, they give the AFR in a wide range that is relevant to tuning. I'll stick with what the industry and everyone else uses for terminology and call that wideband. We'll have to agree to disagree. Is this $900 sensor you're talking about a zirconia sensor? If not, you're talking apples and oranges anyway.

I understand how the TTS will tune the closed loop areas of the 07up map. What I do not understand is how can this tool be used in the same way to tune the open loop areas. With the Twin Scan I would use the "narrow band" sensors supplied and be able to get the AFR I desire out of the stoichiometric range closer to 13.5-13.7.
TIA for your help and time

[Steve Cole]

Let's say you take the calibration and set it to run closed loop everywhere, then set the closed loop bias table to 600mv everywhere. Now load that calibration in the bike and run it. What happens? You tune the VE table everywhere but Decel to about 14.2 AFR event though the AFR table say 14.6. Now doesn't that about cover it. Once done tuning the VE table with V-tune you simple reset the AFR table to the original values and load the calibration and finish by doing peak power WOT tuning. The VE values once set never need to be changed again unless you change parts on the bike. If you want to make it richer or lean simply change the AFR table.
Hope that answers it for you.

The industry does not call them wide band sensors. They are called lean burn sensors to be correct. They were develop for Honda first then other OEM's started to use them in some limited applications. The aftermarket suppliers is who changed the name for marketing purposes. The original sensor designs were done by NTK and Bosch followed. I know it only a name to some but names mean something and I like to use the correct ones so when talking with labs they know what were talking about.
