Well, as a few of you know, I traded the FXSTSSE in on a 2008, 96 ci Street Glide and have spent the first half of the winter chroming and changes tidbits out in the garage.
Trying to buy a SERT off EBay #32107-01H and a friend tells me to forget what's in the SE Cat. ---they have a 32107-01L now that's different!
Apparently he's right.
What's the difference? Anyone know for sure? Could I use the "h" if I get a deal on one or is it outdated?
All I have done is bolt on a set of 2006 SE Slip ons ( the slightly illegal ones that were made by SuperTrapp and discontinued by H-D) and all I plan on doing is adding a SE aircleaner/K&N  - I'm assuming there will be a decent MAP since both are H-D parts.
Thoughts??

As far as I know it is just the software - the actual tuning program.  One of the members kindly posted a link on the site a while back and I downloaded it.  You can also buy a current cd-rom from H-D for about $15 I think.  The dongle, the 'black box' itself, has not changed to my knowledge.

......What's the difference? Anyone know for sure? ......

This should answer all your questions ..... or create new ones.

Each model year I believe they rev the SERT. Not sure what differences they make but according to the tuners (and I use that term loosely) they have a history of taking away tuning abilities with each release (epa I suppose). Since none of them ever got my bike right... I'd consider one of the after market solutions like a PC or TMax. I just put a Tmax in my bike and, while it's too soon to know for sure, it's way better than any SERT tuning I got. If it continues this good, I'll ebay my ecm and sert in the spring. I'm done worrying about HD's warranty. They can't seem to fix anything anyway..

Harley has consistently added features to the SERT year after year.  The revisions from year to year typically add more maps to cover the current years models as well.  The Stock ECM is one of the most advanced fuel injection systems available on any motorcycle today.  The SERT allows complete control of that system.

You might consider keeping your stock ECM and SERT, some day you might regret having sold it.

well, bottom line seems to be that I DON'T need the newest since I ride a Touring model and should have no issues with the "h" version after all.
A few on Ebay for 25% off MSRP so I might take advantage of one - still a little scared to buy off someone other than a HD dealer though, since these things marry to the ECM and are useless afterwards to anyone else. Think I need the peace of mind that comes from buying from a guy with 500+ positive feedbacks and a building with a HD sign out front!
thanks for the replies

I believe the only difference between the "H" and the "L" is the software version and that disk can be purchased online for about $15 (from Zanotti's HD).  I believe I saw that it was posted here for download as well.

Hey Spinger, is it necessary at all? I have an '07 SERK, and a new "H" version SERT I'll be installing after my new motor's built. What does this new "L" version software do for me that the "H" version doesn't?

Hoist!

The PDF document post in reply #2 pretty much explains it.  To sum it up, the "H" has problems communicating with some '05 models.  The "L" has some different maps.

Please correct me if I am wrong but with the latest revision, you can adjust the CLB tables for BOTH the front and rear cylinders. I don't "think" you could do that on the last version could you?

Thank you. It appears I won't need that "L" version or any of the attachments with the 32534-"05B" version ECM on the '07 SERK. The 32107-01H version should work just fine!

Hoist,
You could get by with the older version provided Joe is not going to run your bike in closed loop mode at all.   Wes/Chuck didn't on mine so I would suspect the same on your bike.   There were some issue fixed with talking to older ECM's / softail I think was what I was told as well as what was said above about the Closed Loop Bias on each cylinder and they added some more maps.

For Beerman I would suggest getting the latest software as it has the ability to do the closed loop bias on both cylinders and will allow them to tune the rear cylinder separately from the front especially when in traffic / cruise for saving gas if he stays in the closed loop mode.

Here is the exact changes from the oem calibration file.  Although they don't tell you everything spelled out.

Model Year 2008 Software Updates
(CD Revision L, 7/15/2007)
• Added Model Year 2008 calibrations and parts lists numbered 96 - 107.
• Added column for 2008 Touring ECM.
• Corrected parts listings for calibrations 73, 77, 83.
• Corrected model year for calibration 19.
• All but two 159 cals have been updated to either 171 or 176.
• Removed HDI cals 89, 90, 91. Replaced by 'All Market' cals.

Thanks for the info Harry. No, he's not running it in the closed loop. After you explained it last time, I was under the impression that I still might need the updated software. It appears like it shouldn't matter though.

Even the last Harley expert motor builder told me that so many things (control wise) had been removed from their tuning that he could not guarantee no decel pop or pinging. I can say this, at this time, for the Tmax. I have had no pinging or decel pop since it tuned in. I was riding home Sunday from the bay area on I-80. I was doing about 72 mph. I decided to pass the cars so I rolled the throttle like I used to have to. I was at 90 mph before I could get around the cars.

I claim no real knowledge of ignition systems. However, I am a very experienced electrical engineer (board level control systems designer). There is no doubt a properly (and I emphasize properly) designed closed loop system should out perform an open loop system. Given the right input variables, it should easily adjust to conditions that the open loop system can not. If you don't think these things can out perform a single dyno tune, I think your living with the dinosaurs...
