Decided to take advantage of the day off and play with the SERT dad left me...

Found some notes, he had it "Dyno Tuned" for $150.00 by Skip's Speed & Custom Cycles in Winchester VA - Aug 05...no notes of what was done, no disks with maps etc.

Note in the kit from 03 was that he had 3292503.mt2 used - appears to be a canned map?  I am guessing the folks at Skips used that as a base and tuned from that?

My bike runs like crap in my opinion - back fires on decel, sometimes even on upshifts, getting crappy mileage (less then 40) and I smell rich conditions when I fire it up in the garage.

Have a 103" map similar to what I am running, Basani True Duals, and a Hypercharger...but am afraid to re-map, cause at least my bike runs!

Suggestions?  Hints? 

I have the Tuner and the Data collection stuff loaded to a desktop that has a serial connection...and have a USB to Serial converter for a laptop I have planned for this.

The map # provided is a base map from what they tuned from.  Not being smart but for $150, they may have just installed the base map and not tuned far from there if any.  Several members on here says it take 6-8 hours to properly tune bike letting it cool down between runs. 
Your dad should have got (took in a mobile storage device) in so he could have a copy of what was done.  If you have that, you can put in your  SERT program in computer, make change in tables, and then download back into bike.
Hope this helps some.  There are a lot of people on here that know a lot more than me on tuning.   Hope they chime in.
All I really know is that if you have a copy of what changes they made, you can make changes in each table oin your own.

SERT with the USB cables has been problematic most of the time.  The older versions of SERT like to be plugged directly to RS232.  A .mt2 file is really an old version of SERT.  The newer stuff is .mt6.  It will be very difficult or impossible to tune the bike with an older version of SERT by the seat of your pants.  You would also need some method of collecting the AFR data with a sniffer probe in the exhaust.  Not very practical to do this while riding around town.  Your best bet is to take it to a shop that has a dyno and let them tune it and not just flash it.  This bike should run smooth and have no decel popping and mileage should be 38-42mpg.  I know this is not exactly what you wanted to hear but a good dyno shop will update your software and also give you a custom tune file for your bike.

I figure to need a tune, no worries there!  I figure that this mc has to run better then it is.

If all you have is pipes and AC, it shouldn't take to much dyno time. You might look around and see if anyone's running a special now that it's off season. I found a local shop this summer that was doing a base line dyno run for $25. I took it in got the run, I had a canned map for pipes and AC. We found a few spots on the AF table that were a little off, one lean, one rich. For another $50 he put it back on and did a little adjustment to the table in these two areas and another pull, it looked better. Although this isn't a dyno tune, the bike runs good! Once I do cams, heads and other major work, I'll get a full dyno tune. Just couldn't see paying $400-$550 since I only added the mufflers and AC.

FloridaMarine,

The canned map is the starting point to go from.   The advantage of the dyno is what they call Stepped Runs and Sweep Runs using a load / brake dyno.

If you want to just get rid of the popping that is pretty easy to get rid of if you have the original map.  If you need help with that or figuring it out or what to understand the basics please shoot me a pm and see what I can do to help with that.  That said, I still recommend a full dyno since you really dont know what you have to begin with across the full spectrum.   

The step Runs allow them to finely tune your bike up to say 20 to 30 kPa.  From there they do roll ons (Sweeps) to capture data from there up.   The advantage to the dyno is they can add and subtract timing and see if it is making a real difference.

You will want to download the latest software 4.77 or wait for Mastertune to sell their upgrade and then you can get that and then they have the automated learning while you ride then all you do is up load the map to the desired changes and away you go.   Although you have to know what the desired fuel you want to achieve is and then it will help set the Volumetric Efficiencies for each cylinder.

Whatever the tuner does if they do not tune both cylinders independently its time to find another tuner.   A canned map may get you close, but if your paying for a tune that should not be an acceptable situation unless you agree to it up front.

If you need version 4.77 send me a pm or an email and I will send you a link to get the latest and last software for the original sert.

Think I found 4.7 on HD Forums - downloading now - 50-60mb or so.  Will install it and see what flys.

I have asked some of the Indy's here, there are no dyno tuners, so I will have to roadtrip for that.  BUT I need to do the gear driven cams soon, and want to get it done after that.  I guess what I was hoping for was a decent map to get me running better then I am now!

Learning as I go!

Sean,

Did you find 4.76 or 4.77 you want to ensure you have 4.77

Where in Florida are you, I am just south west of Daytona.
