'05 SEEG that we dyno'd with a SERT ..ended up with a/f at wot of 13.4 ..nice flat line. Cruise numbers were 14.0 ....made just under 100 hp and just over 100 tq ..with a/c ..factory exhaust and one piece SE II slip-ons...I'm used to how it rides by now.
So I'm bored yesterday and i'm looking at the various caned maps in the SERT.
Looking at the CVO Fatboy maps.... I lowered all the target a/f numbers to a max of 14.0 for both cylinders...cut the Decel Enleanment numbers by 50 % for popping and left the VE numbers and timing alone as the tables are much more aggressive than the E-Glide map.
Loaded it and rode.... Starts better hot and cold...Idles smoother...throttle response WAY better.... it will now pull the front tire a couple of inches on a 1-2 shift..WTF ??
I'm leavin it this way till I can get it back on the dyno. ..I'm picking up some fresh plugs so I can get a good read on them..run the bike on 94 sunoco...My but dyno is telling me its gonna have better numbers ....

What is the map number you used?
I used #13, 127HX022-A1.MT5
SE air cleaner, V&H ovals with true duals and the above map. No dyno yet. Raised the rev limit to 6k and on a hard run 1st-2nd shift pulls the wheel 2-4".
I just looked at the data, seems most of my test run the AFR was between 14.2 - 14.5
I do have a decel crackle and the occasional decel backfire.

My exact setup soon, I wonder if I could put the Race tuner in myself and map it myself and save a bunch of dough!

Remove the right side cover, plug in the module, hook up a laptop (easiest, not required, could use a PC), download the map
GO out and enjoy.

I'm running map 127MK004-A1 .MT5...05 CVO Fat Boy.....Should be where you would want to be as the true duals change the VE's on both cylinders . Reduce all the target A/f ratios for both cylinders that are above 14.0 down 14.0....Make sure to cut the Decel Enleanment numbers by 50 % for popping and load it. I made some other changes cause I'm just running the stock exhaust with SE slip ons and a/c of course.....If you look at the ve and timing differences between the two maps you will see that the 127Mk004 is more "aggressive"
-
I'm going to guess that the timing is more aggressive due to the bike weighing a lot less.

Put a 300 lb guy on the Fat boy and a 150 lb on the E-glide and your about equal.
The reason for the difference is the change in exhaust scavaging and fill due to the exhaust difference (2-2 vs basically 2-1) and the extra load to
