Thanks for the offer, I appreciate it.

I had to pick up some other parts and just decided to get the software and cable.  I had a 20% discount so I figured I might as well pick them up.

Now I'll have to do some reading and figure out how to use it.

When I hook in to the bike for the first time do I have a risk of erasing the current map?

Did you ever resolve this?  I was fighting this same stumble on my '10 CVO SG with Feuling 574 cams, Fullsac x pipe and V&H Hi Output slipons.

I pulled some fuel from the Accel Enrichment table and leaned the Main Lambda table from 1000 - 1500 rpm.

So far, I seemed to have eliminated the stumble.  More testing to come.

Another discovery this morning...  The WarmUp Enrichment table is adding fuel (in my map) throughout the warm up range...  From what I read, it should taper off and then add fuel at the hottest cells.  Right?

This is what mine looks like

-16  0.217
0     0.185
16   0.158
32   0.137
48   0.130
64   0.125
80   0.115
96   0.108
112 0.094
128 0.084
144 0.075
160 0.068

Every map I ever saw has the warm-up fuel table degrade as the temps rise. The warm up table is activated every time you restart the bike....the hotter the temps the sooner it shuts down, however if someone was trying to fix a hot start problem by adding fuel in this table I can see where you would see higher numbers in the higher temps. The warm-up table will not address a hot start problem....you would have to use the Cranking Table for starting fuel problems.
As far as the hesitation off idle, or leaving a red light/stop sign situation, I would add or subtract fuel in the 750 rpm area in the VE tables........as you take off the rpm's fall below idle rpm at times and I have found getting the VE's right in the 750 rpm row is a huge gain in low end stumble problems.

Thanks Doc... I didn't think about the RPMs dropping at take off. 

I just spent $450 in two separate tuning sessions at Colonial HD... only to drive away and have that off idle stumble more present than ever.  GRRRRR!!   I'll reduce the fuel on the VE tables @ 750 rpm and try it out.

Will post results!

interested in what you find with this, im having a similar issue but its not consistent... its done it since day one & i have had it tuned with fullsac pipe, better... cam, heads, pistons... better but it will still do it if it feels like it?

So.. I was able to eliminate MOST of the idle blip stumble... not all.. but most, by pulling fuel from the Accel Enrichment table.

I am going to dump the Feuling 574 Cams and go to the Andrews 54 or 57 Cams.  I am not thrilled that the Feuling Cams make torque beginning at 3700 rpms.  I am looking for more down low.

The 54 cam suffers at bottom end also.....the 57 is a way better cam than the 54, however your 255 is the best for the bottom and midrange torque......yes the ones you took out......lol

Doc, you don't go out to Sturgis with a Dyno... do you?

Doc, you don't go out to Sturgis with a Dyno... do you?

No....my dyno is bolted to the floor in the shop...sorry...however you can always come here....just pack up the family for a Disney trip and bring your bike.....lol
