I bought a SERT last year at my local dealer. I made an appointment to have it "intsalled or whatever you call it" along with my Rinehart true duals. After they were finished with it, I rode it home but it didn't seem to be any different than when I took it there. (Other than being louder.) It seemed to run about the same.Here is the question; after inspecting the packaging that the sert came in, I found a small box inside the outer box that had a little rectangular black thing that looked like you would plug wires into. Also there was a "CD" in there. The "CD" wasn't even opened. Which part causes this thing to be "married" to the bike? If it is the "CD" than they probably didn't make the changes to the "ECM". Am I right?
Because the bike didn't seem to run any different, I wonder if this is possible? The fact that it didn't run any better is why I had a PCIII installed at Johnstown this year. Anybody know about these things that could "splain" it to me.

 

You can use any version CD. I am sure that they had the software already loaded on their PC. It's the "black box" that they needed to use. Unfortunately HD is too cheap to provide you with the cables to hook it up yourself. You can buy the cables from them.

 

As far as I know, the race turner from Harley does not stay on the bike after it has been installed.The PCIII does and the fuel pac from V&H does also. I have the PCIII on my bike with a map from Fuel Moto and noticed a lot of diference in proformance.The gas mileage sucks but it sure does run good.Going this Sat. to get dynoed.

 

Yes you are correct about that however, my question is; is the black box the part that makes it unuseable for other bikes. The black box didn't stay on the bike either, so does that mean there is a card inside the box that the computer reads so that it knows it has been used before? There has to be some way that another bike knows that it has been used. I would have thought that this information would be on the "CD". You know like a serial # embedded or something that the computer overwrites so the next bike knows that it was used. If this is not the case, than, there almost has to be a card in the black box that stored information that says it was used before.

 

The black box does marry it to the ECM. and cannot be used on another bike. However it does not stay on the bike, you connect it, communicate with the ECM, make changes, downloads etc, then unhook it, the CD is the programs and canned maps, it is the software, load it your computer and then you don't have to have the CD. it is not married to the ECM.
So basically, you can load that CD in any computer you want, But that black box you have is Married to your ECM and will not work on another bike.

 

Well that sucks. So Harley ( or who ever produces this kit) produced the "card" that is in the black box in such a way as to read a code from the first "ECM" that it is hooked up to, remember or document this information, and then not allow any further information to go past this black box unless it reads the same information from the same ECM the next time it is hooked up. Or, the ECM sends out a code or ID# to the black box that the ECM can read in the future if further changes need to be made. Seems like a lot of crap just to keep us from using it on another bike.

 

Hammerhead,
Just so to sum it all up for you (I think you have it now). The little black box is the "interface" that allows the SERT programmed laptop to "talk" to your ECM and download the appropriate maps, info, etc. Do not lose the interface "blackbox" it is now part of your bike for SERT tuning. It is now part of your ECM. And as prevuiously explained, the cables and CD aren't nessessary if one already as them.

 

Thank you. Thats all I wanted to know in the first place. I never was any good at reading between the lines. I just wanted to know which part marries it to the bike and how that happens. Since the dealer didn't "use" the CD I thought that maybe they didn't actually do the programming. Actually, the way it was running after I picked it up, they may as well have "not" programmed it. It runs " much,much,much" better now that I had the PCIII installed and the dyno done. The only problem I have now is that it shuts off after it sits at idle for a little while. It only happens once in a while. I took it to the dealer because the dyno guy said that I was having fuel canister problems but, the dealer put a pressure guage on it and the pressure was fine. At least it was at that moment. I am going to get the canister replaced under the recall and see if that fixes it. If not, then I have to see if I can get the PCIII replaced.

 

I don't know why the marrying part is such a strange concept. Most auto ECU tuners do the same exact thing, they marry to the ECU so that they cannot be used on another vehicle. Why? So that the companies that make them can make money! Otherwise a tuner shop would buy one and use it on all vehicles.

 

The CD contains canned maps and instructions on using the SERT.

The install of a SERT is simple.
You need two cables. Plug one cable into the bike and into the SERT. Plug the other cable from the SERT to the computer. Turn on the bike and computer, make sure the SERT is communicating on the serial port from the computer to the SERT to the bike. The SERT then marries itself to your bike.

Here comes the FUN part!
Download a canned map from the CD to the bike as a base line. Then have someone, that is skilled and knowledgable, tune you bike on a Dyno using the SERT. The tuning will cost approx $200+. Unhook the SERT from your bike and you're done. Then next time you will need the SERT is when you make additional modifications to your bike. Cams, jugs, heads etc. Make sure you get a copy of the new custom map on a thumb drive to take with you.

Sounds like they married the SERT to the bike, installed a canned map from the CD and sent you on your way. Unless they used a map they have already programmed with your specific configuration. However, for best performance get it dynoed with the SERT.

I personally prefer the SERT. Much more configurable then PC.

Recently, the relationship between TTS Mastertune (the folks that make the SERT) and Harley has disconnected. Harley now has a "new" product called the SERT Super Tuner. You can now access TTS Mastertune on the web.

What other modifications have you done to your scoot besides changing the pipes?
