If I transfer a TTS with ECM that it is married with to another bike and then change the VIN in the ECM to match the bike it is now installed in, will the TTS/ECM marriage be broken?

My internet searches "lead me to believe" that the TTS is married to the ECM serial and not the bikes VIN.  However, I've found several posts that leave me with some doubt about this.

Can anyone clarify this?

Just transfer the ECM and SEST as a unit to the new bike. Don't worry about how the dongle is married, just use it as is...not further action necessary.
If you absolutely have to have the VIN matched to your bike it will take a trip to the dealer and maybe some $$.

Thanks for the reply, however its at TTS and not a SEST. 

Its my understanding that the ECM needs to be programmed with the correct VIN for the bike its installed in to properly interact with the TSSM and Speedo.  Is this not the case?

The TTS marriage won't be broke since the ECM and TTS were already married, but the new to the bike ECM needs to be matched to the TSSM in the new bike for it to start and work.

So if I'm understand correctly, the following will not pose any problems;

(1) Install the ECM from a 2011 FLHTK and TTS married to it into my 2010 FLHTCUSE5 bike.

(2) Unlock the ECM by restoring the backed up MTE file from the 2011 FLHTK (MT8 CAL for the previous bike currently installed in the ECM)

(3) Have the dealer use the Digital Technician to change the ECMs current VIN to my VIN and then download and restore the latest ECM firmware and configuration for my VIN without breaking the existing TTS/ECM marriage.

(4) Marry the ECM to my TSSM (either using the Digital Technician or the manual TSM/TSSM ECM Password Learn Procedure)

(5) Make a new MTE file using the married TTS.

(6) Use the TTS to install a compatible TTS map and begin vTuning.

I HAVE SWAPPED TTS ECMS!

You do that?  In the above post? you WILL lose the marriage.  ANd.. I assume that marriage of the ECM to TTS is what is driving this, right?  Can you get the TSSM from the donor bike?  If so... it is PURE plug and play.

I have done this.  I installed a 2009 ECM into a 2010 bike, due to 1). The 09 ECM was already married to the TTS; and 2). I wished to keep a TPS calibration at that time (no decent Lambda cals for a 120r). (I had to rewire the O2s to do this, and you will not).  PURE plug and play, except for the TSSM.

I also pulled the TSSM .

AT first, I married my 09 TSSM to the 2010 ECM., I used the speedo calibration method.  It takes awhile but it DOES work.  Then, when I installed the 09 ECM, that ECM recognized the TSSM right away.

The VIN will HAVE to stay whatever it was on the old bike.  That helps keep the ability to shoot calibrations and has really?  Nothing to do with the 'marriage' between the TTS and the ECM.  THAT is married by an internal switch inside the ECM and the TTS software.  Except for the fact the VIN runs what cals can be used, and therefore DOES become part of the marriage.

If you try to mess with, or have a dealer mess with the ECM and the VIN inside you will lose the ability to enter calibrations, because there IS a bit about being 'married' that carries thru.

Here is what I recommend.  Install the ECM.  Traet it normal, and just like you did on the old bike.  Find the instructions on how to marry a TSSM to a bike using the speedo.  It will take like an hour to figure out and get it done.  But... once done, you will have a bike that you can use TTS on, and the TSSM, etc will all work fine.  Only downside is if a dealer pulls up the VIN, it WILL be wrong.

As a smart consumer, when taking the bike in, you need to SAY some things right up front.  Tell them the VIN does NOT match the ECM.  That the bike was tuned with TTS, and when the message come up on the DIgital Technician, that the service tech is to DISREGARD the message that pops up saying the ECM is corrupted... have the dealer try skipping past the message (it will!), and then they can bleed ABS, pull codes, etc.

I lost the speedo procedure, but I had originally found it on HDF.

Shoot me an email and I can talk you thru this thing if you wish.

If you can find a good Indy that has a techno research set up and familiar with TTS. They can take care of all this for you in about 1/2 hour.  Just trying to give you another option besides the dealership.

The VIN has to remain the old one.  The thing is Techno can marry the TSSM.  The speedo method works as well.

Search TechnoResearch.com for tuning centers.  If one is close by, call and see if they have Centrurion SUPER Pro, not just Pro.  If so, they will be able to marry the TSSM.  A dealer will NOT be able to make the marriage you are contemplating.  Well, maybe... they will HAVE to leave the VIN alone for sure.  Install the MTE, have the marriage done, and re-install the calibration.

Why do you care if the VIN is correct?

[HDGearHead]

I've done the procedure to marry the TSSM to the ECM several times in the past without problem and have the procedures bookmarked somewhere.

I also understand the VIN is used in a safety check to verify that you're not programming the wrong code for your bike.

Base on what I have been able to gather on the internet, I'm under the impression that the TTS is married to the ECMs seed key and not the VIN.  If the key written in to the TTS matches the ECMs key, all is good. 

I have found a lot of contradictory information across multiple forum sites regarding whether or not the ECM VIN change and Digital Technician program update will render the TTS useless.

To each their own, however I personally choose not to run a ECM in my bike useless the ECM VIN and loaded program match my bike.  I don't want to have to deal with the potential hassles and questions that may arise during service work, ESP, LEO, resale, etc in the future to save a few bucks on a bike of this value.  I might not care if it were just a cheap POS rat.  Like I said, to each their own.

I was looking to buy this ECM and TTS from another rider that moved on to another tuning solution.  While the sale could benefit us both, if I can't change the ECM VIN and update it program with the digital Tech before I begin tuning with it, I'll walk away and spend a couple of hundred more to buy a new TTS and ECM instead.

I don't see any LEO issues.  VIN is NOT inside of the ECM for ant-theft procedures.  The rest?  The service issues?  If you have a TTS, regardless of the VIN and you go to a dealer, you WILL have issues if you are not a proactive consumer anyways.  The digital technician will show issues on the load up page, because a TTS shuffles the internal partitions, anyways.

Good tuners, nowadays, who tune with a TTS, will give out a sheet listing how to approach a dealer with TTS installed.

I think if the deal is OK moneywise?  The issue with an internal VIN shouldn't be a reason to kill the deal.

How about calling Steve Cole on Monday, and find out about VIN changes, instead of relying on us?  And... before you call, think about what TRUE issues you could have?  Just because I have done it.  Done it successfully, doesn't mean there could not be another way around the barn.  I DO know my work WILL work, so you know.

ANd... why would you need to buy a new ECM anyways?  What happened?  TTS is $425 and an ECM is like $300.
