SERT, What is it? Get your answers here !!

OK, everyone says you can't save a "stock" map, right?
But if the only thing a SERT can do is make percentage changes from whatever map is installed at the time, like a stock map, why can't you just save a map that has NO changes. One with ZERO's in all the blocks. Wouldn't that be the same thing as saving a "stock" map?
Or would reinstalling a saved map like that just make no changes to whatever map happens to be in there at the time?

I think I'm confusing myself now.

The SERT program writes complete new calibratiion tables to the ECM. It does not make changes to the ECM data, it re-writes the data completely when you re-program the ECM.

To be ready to re-program the ECM, you pick a canned map from the list of SERT calibration maps (or start with a previously stored map on your computer). Based on the tuning data obtained from a dyno, O2 sensor kit, or SOTP, you (or your tuner) makes changes to the map stored on your computer. When you are happy with the revision, you download the new map to the ECM, try it out, and re-tune again if needed. Your starting point for the next reflash is the version of the map that is saved on your computer. If you lose your last saved map from your computer drive, or don't get the latest version from your tuner, you have to start all over from an earlier version of a map saved on your computer.

The SERT software does not incrementally change the ECM's programming tables, it re-writes them completely. The incremental changes are made to the version of the map saved on your computer.

Thank You very much, that explains it very nicely, well I guess you CAN teach this old dog some new tricks.
Hmmmm, I wonder if the actual communication protocal is open sourced? If its a two way system, and I believe it has to be, at least partially, it "should" be possible to interogate the ECM's EPROM directly to see exactly what's in there.
I don't have a SERT or the software, yet, so can anyone who has one look on the CD and tell me if the "canned" MAP's on there include one for a plain Jane Stage 1 SE pipe and AC upgrade? If so its probably more trouble to try to figure out how to interogate the ECM for the stock MAP then its worth.

BTW they released a ECM MAP update for the early 07 bikes. I had it done to mine and it does make the bike run better/cooler.
Has anyone thought to ask a friendly dealer tech if they could make a copy of it for them on a diskette? That would get a copy of the latest stock MAP to start experimenting with and fall back on if all else fails. Assuming that its downloaded to them in a format the SERT's program can read, and they can copy it to a diskette for you.

Sorry if any of these questions have been asked already, I read the whole thread, but I'm still a little fuzzy on some of the little details.

Getting older is a PITA I'm losing the hair on my head, but growing fuzz on the brain, or maybe its just from wearing a helmet too much. Thanks for the patience.

yes, there are MAPs for stock motor with stage 1 air cleaner, and pipes.
and you can make adjustments to every table, if you feel the need.

The only adjustments I made were to make the AFR table for both cylinders richer, and I also advanced the timing 2* across the board.
and I did lower my idle a little bit to 975rpm when the engine is at operating temp.

I also bought the DTT twinscan II+ and Wego IID, to street tune my bike.
I made my first run yesterday!

Great post; so apparently when u buy a sert you get a cd,manual and a cable to hook computer to ecm, right? or am i all wet.

The new SERTs are a cd (with tuning software, data collection software, instruction manual, and list of calibration tables) and a hardware interface key (sometimes called a "dongle"). The interface key goes in the cable that connects between the computer's serial port and the bike's diagnostic port. Cables are a separate part number with the new SERT, they were included in older versions of the SERT.

What is the latest version of sert available, whole package. I have a '07 Street Bob.

Right,
consider that for 2007 SERT is not available through official dealers here in Italy.
So which is the latest Software and Harware version available and which is the best place to get it online?
Thank you all

[springer-]

Latest software is 32117-01H
Latest SERT is 32107-01F
Need cable set 32108-06

Online Dealer ... don't know if they ship out of the country.

thank you springer, I know the guys! Will find out.

Thanks, Springer; great service to those of us who were "afraid" of the SERT.

I pick mine up today and will tune my bike tomorrow with a friend who is a degreed mechanical engineer who learned the SERT tuning regime by reading the manual, studying it, and then tuning his '06 Classic after wrenching HQ 95" kit.

After I tune the bike doing controlled runs and getting what I believe is a good tune, I will take it to a dyno to confirm what I have. My friend did this and his tune was excellent, though the dyno did show a very lean condition at WOT at a particular rpm that he obviously did not intentionally create. So the dyno will be my back-up plan to avoid any serious mistakes or oversights.

Thanks, again, for your efforts to educate me and others willing to stick our toes in the SERT pool.

By the way, the service manager at my dealer did me a big favor and used the HD dealer-wide inventory search and found older versions of the SERT sittiing in dealers and printed out the info for me. I started calling them looking for a "deal" and found a version for '04 at a NC dealer and bought it new in the box for $321 which came with the cables. Incidentally, the part number for the data link, the "key," is 32114-01A, and should be in a tape-sealed brown carton. It's the key that "marries" the SERT to a particular bike's ECM and if the key has been used on another bike it won't work on another bike. So if you shop eBay for a SERT, or talk to a dealer, be certain, absolutely certain, that you get that part number (it's printed on the box) and the box is sealed. (note: that part number won't be found on the HD parts inventory as it is not available for seperate sale.) There is no problem buying an earlier version of the SERT 32107-xxx, provided you have a friend with the CD version for your bike, or are prepared to spend $20 bucks for the CD from Harley.

Anyone know when the latest software and map revision is due out from H-D?
Wasn't there an update around this time last year?

[Romzi]

Hi to all!
I have read this post from the beginning. Tons of info Thanks for all of them.
I have a question too, just to be sure.
I have FXDWG 05 and i decide to purchase a SERT.
Probably i don't need the latest software update right?
What number should i order for 05 fxdwg?
I have mounted Super traps and Kuryakyn skul air filter.
Ps: My bike have just speedometer without RPM counter, that will make tuning a bit complicated.
Regards, Romzi

The data recorder records your RPM's (part of the SERT).

Just released..........latest SERT Software is 32117-01J. They skipped ver. "I" for obvious reasons..........
