Problem is the stumble is there in first gear or fifth or third,like when you blip the throttle to downshift.You get nothing but spring load and no or little response.You have to get the rpms up a bit to get throttle response. My wifes 2010 sesg is no problem. Im wondering if its the pipes or the computer.

Mine does it to when down shifting.  Maybe a result of my combo but I think some fine tuning would definitely help.

I'm wondering if I get a TTS can they extract the map out of my SEPST?  I would hate to destroy a good tune.  My bike runs like a raped ape everywhere but off idle.

Tim; thanks for the help!  I'll definitely give him a call.

You need to buy nothing more than the software and cable. But there is a snafu maybe. I am not sure if you can download your current map in the ECU, work on it, then return it. If you have the current map on disk, the map file, then you are good to go. Glens is the SME he would know if modifying the installed program is possible without a disk backup. If you can't you are looking at a retune. The TTS or the SEPST are both capable devices to get that accomplished in the right hands. No need to throw the baby out with the bath water.
Glens' analysis concurs with mine
"An alternative would be to adjust the Acceleration Enrichment in just that area."
You will find, based on my experience, when cams and so on are changed they usually need a little "less" not "more" fuel.
I am assuming the mechanical condition of the components is all good, especially intake seals, and also the O2 sensors are properly placed in the exhaust stream and isolated from crosstalk from each other.

I believe the SEPST unit itself contains a copy of the last calibration uploaded to the ECM and that that copy can be retrieved and worked with.

Had the same problem. Since the bike had been running perfectly for 9000 miles since installation of TTS & a dyno tune, I suspected that the problem was either an electrical or mechanical malfunction . The replacement of the twist grip sensor assembly pn 32310-08, cured the issue. I had ridden about 900 miles in the rain just prior to the start of the hesitation. Part was replaced under my ESP.
(Boy, am I glad my dealer talked me into buying an ESP. Has paid for itself X 2 already!!)

Sounds like getting the software and cable is what I need to do and go from there.

I was at my brother in law's today and he has a sweet street 08 glide with a 113.  He went from a SERT to a thundermax and seems to like it.  His throttle response is crisp and responsive.

I've considered the Tmax but can't get over replacing the stock ECM.

[glens]

I'm sure there are some off-the-wall engine builds that the Delphi can't handle properly where the TMax would work well.  Without having to go to a replacement ECM like that, I'd consider it a waste of money to swap out the Delphi.  Also, I'm fond of having a MAP sensor used in various ECM calculations for both fuel and spark timing.  Last I knew, TMax doesn't use it for anything (except maybe getting a barometric reading at startup?).

It might be only the orange SEPST units which hold a copy of the last calibration burned to the bike.  If you have one of the earlier (I think black) units it might not do that.

[2006ULTRA]

I have the Orange one.  I found a couple video's of the SEPST on youtube.  Didn't really learn much from those videos but it looks like it has a lot of capabilities.

[glens]

Yeah, you can get the job done with it.  Some of the way the software does things is a little funky/unexpected compared to other systems, and the user interface doesn't leave much middle ground: you pretty much either love it or hate it.  I don't love it...

Return to HD, ask for a stock ECM flash (it's free)...order a power commander 5 from fuelmotousa.com with it already mapped to your set up. Sorry that you are stuck with a useless SERT, but unless you are a gifted tuner, good luck! I have been to classes and worked with a guy who knows the ins and outs and he likes the PC5 better. And you can even run an auto tuner with it and call it a day.

I like this idea but I'm afraid that with my luck the bike will never run as good (other than the throttle blip) as it does now.

They shop that did my build has a pretty strong formula for the 110, they have been doing this combo for years and it makes a ton of HP and TQ.  I'm sure some of this power comes from timing.  If I go with a different tuner I will lose that advantage with a new map.

Question; If I get the cable and software for the SE Pro Tuner can I look at all the tables and print them off, then if I change tuners just duplicate those tables and create my own map?

You wrote in your initial post that the bike already had a SERT.  Why not continue using it since you already own it?

[2006ULTRA]

I'm sure I will unless I can't get the throttle stumble out of it. 

[Bigjim1661]

  the cable is just a usb to printer cable. I take it you have your little orange box? I can send u a copy of the software.

[2006ULTRA]

That would be great!  Don't I need a special end on the cable to hook in to the port on the bike?

Yes I have the Orange box

[Bigjim1661]

Yeah...have that too. Email me your.address. holeshotchoppers@gmail.com
