Hi all - I have added a Stage 1 SE Air Cleaner and V&H Big Radius pipes to my 96" Night Train(softail).
I have a TTS tuner which is a great bit of kit and uploaded a map which matched my specs I found on another site.

At the moment I still get a burble and pop on decel, can anybody suggest a map with similiar spec bike to reduce this?
I can't uplaod the map, but if anybody requires it I can email after a PM.

Cheers
Matt

 

Maphew if you have just uploaded the map and made no adjustments then the map is not tuned to your bike. The map is only a starting point. You need to do a few Vtune runs to bed the map into the bike. Have a read of the tuning guide and go from there. You will also get plenty of help on here if you get stuck.

The reason you are getting a pop on decel is that the map is not tuned to your motor that's all. It may settle down after a couple of weeks as the ECU learns the requirments of your engine. But in the end you are using a map developed by someone else for their bike.

Try a few of the Master Tune canned maps, e.g. CAA176-03, CAE176-03, CPZ176-03 or CQD176-03. These are for AC & exhaust mods for 1584 Twin Cams with stock cams. With my 113 rebiuld, I tried several different maps, & ended up settling on two that ran really well.- Rob

Thanks for the replies, I'll try the VTune. KiwiRob thanks for the suggestions, I had a bit of trouble reading the map catalogue!

Try the free download calibrations from Kuryakyn's TTS web-page

There are some Calibrations there for 96 cube bikes with V&H exhaust systems

All in a wee hidden drop-down menu by model or "platform"

http://www.kuryakyn.com/products/1620/tts-mastertune

Bearing in mind that in my experience V&H straight pipe systems are the hardest to " fix " the popping on decel'.

I have used them quite successfully to tune bikes fitted with Samson straight pipe systems and the like.

Iv'e looked in there and can only find one mt8 file...with 6 maps all up...Am I looking in the wrong spot...

Wee drop-down menu , right in the middle of the page

Listed under Softail , Dyna , Touring etc , all in drop-down menus !

There is a cal for " 2007 to 2009 Softail with V&H straights " and it's an MT7

( There are about 20 different Softail Cals 2001 and up ? )

Remember you can try the Dyna and early touring cals ( up to 2009 ) as well in Softails.

I have used the early "Touring" cals in Dynas quite successfully to date.

I programmed a different map with the intention on testing on the weekend but on startup I got a bit of a backfire and smoke out of the AC.
So decided to go back to the existing map. I did some reading on the VTune using Datamaster to collect data which I believe needs to happen about 3 times or 5% of change.

Question 1 - what riding style is needed to complete VE table or just ride as per normal?
Question 2 - assume the backfire was a result of new map, never had a backfire before?

Maphew. As far as the riding style goes Ok you need to think outside your normal style.

Load the map you intend to use, Setup the computer etc for recording along with Data master. Start the bike and allow to warm up. Don't start recording until you get the green light through Data master. The hit record check that it is recording data and secure the laptop.

Find a quiet area that will allow you to conduct the tune. The aim is to allow the system to record each cell for about 7-10 secs. The easiest way is to count to 10 slowly holding the throttle in position at a given position, Note the speed reading. Do this in 10kph increments. Do this all the way to red line, and then back down, then swap to alternate 5kph increments. So 10 -20 -3- 4- 50 etc, then 5-15-25-35-45 etc. Do this for a few runs, then DON"T turn off the bike. Save the data master recording and have a look at your tune. If it is ok blend and do that for a further 2 -3 runs.

It is going to take a few runs to get it right. Best way is to post your file /screen shots here so the blokes can have a look and offer advice. If you have a look through this place you will find a few threads on the tuning procedure. The PDF file that came with the program is good but there are some up to date changes to the procedure that have come out lately. Ref Accel and Decel.

Ok.

Have a good look though the map that you are using. Check the things like Idle, remember that anything lower than 900 may cause damage to your motor. 960rpm is not to bad an idle. The AFR table, cam settings, do a cam run on the Data master anyway to check. Warm up enrichment etc... And the biggy the front and rear CLB tables... a lot of the US maps have a rather lean looking CLB table. Most of us run then around the 700 and 720 settings across the board. All of this can be done prior to loading up the map to the ECU. Every time you make a change to the map it saves it sequentially 01, 02 etc, so you will have a lot of maps if you are not careful and it can be quite confusing if you coma back to it at a later stage. So sort yourself out with file names, comments and a new folder to work from.

So you hook up the tts set it up to record etc.Once you are happy that you are getting hits Go for a ride. The reason you need a quiet spot is that you will be breaking the speed limit at some stage...

Take of in gear 1st, 2nd normally. When in second you can start the tuning process. 20kph, hold for 10 seconds, then 30 kph 10 secs, 40 kph and so on right up till you hit the rev limiter. You will know as the engine with start to cut out.. Let it back down through the rev range using the same principle. Then 15, 25 etc etc all the way up to the rev limiter.

Do this 3 to 4 times, also on a couple of the runs when you hit the limiter let the throttle off completely all the way back to idle and then go through the same system again. You want to do this for about 20 mins. Once you think you have got enough info pull over some where quiet or ride home, Do not stop the engine, allow the engine to idle while you get the laptop out and check the hits that are indicated on the data master screen.You want green squares in a diagonal line from top left to bottom right of the screen. A lot of white means not enough hits in that cell. You can tell what the rev range was by the left hand side of the screen. At this time you can get the required hits for the idle as well. Stop the recording using the buttons and make sure the info is saved. Then you can turn off the bike and go through the blending process.

FYI, I do mine in 2nd and 3rd gears and then 4th as well, at that stage you are over the speed limit. That's why you want somewhere quiet. In the manual it gives you an indication of an acceptable vtune file that has enough hits. Blend the file, load up the map and go out and do another run. The more hits the better. Also the screen will let you know if you are getting enough hits in the right areas. And if you need to concentrate on certain areas. it is a lot of hit and miss in the end. If you are not happy with the file. Dump it and do another run.

As I said if you want you can post your files on here or take a screen capture and post it up. There are plenty of blokes who are more than willing to help out if you are stuck. Have a look through this forum as well as Hilly is right up there with tuning using the TTS. The key to the whole thing is the first run get that right and the rest is a lot easier. If you don't get the first run as close as possible then you will have issues the more you tune.

Also you don't need to do the whole thing is one day, if you want you can do a couple of runs and keep the files to have a look at later, blend and then come back to tuning at a time that you want. All up you are looking at about 3 hrs for the start then you get into Spark tables, etc...

Any thing you are stuck with post it here and someone will help.

And TAKE YOUR TME. Have fun. It will do your head in eventually, especially when you get to the finer points of the tuning process...
