[Beak Boater]

Bought a Used bike from a dealer that was tuned with a SEPST. The seller did not trade in the VCI. I know the tuner is married to the ECM, and I will have to buy another SEPST if I want to change anything in the tune. My Question is how does that work? Does the new SEPST delete the old when its installed? Does it override the old tune when the new one is installed?
Bike runs good, just thinking ahead If I lose the tune for some reason or want to make a change, don't want to screw up the tune.

Yep.....Dealer wont release owners name to me because of privacy clauses, they said they would contact him and said he never returned their calls.
Bought the bike knowing this could be an issue. Was just wondering how the second SEPST works when installed, if I need too. Does it just over ride the first that is married to the ECM?

You don't exactly "install" a SEPST, you just use it to communicate with the ECM.  If you use a new VCI to communicate with the ECM, nothing happens until you actually load a map.  It's not like if you connect it the ECM immediately loses it's current settings.  However, if you do load a new map I don't believe you can undo it with the SEPST unless they've changed something very recently.  Other tuning solutions like the TTS or PV allow you to save the existing map before you load a new one, in case you want to go back later.

btw, if what you are really talking about is whether or not you will have a problem with the ECM refusing to talk to the new VCI, the answer is no.  Some other systems do lock the ECM to prevent other systems from overwriting their maps, but the SEPST is not one of them.

Thanks for the explaination, that's what I was wanting to know. Hadn't really though about it locking it and not letting another system communicate.
Wanted to stay with sepst, was told that my ESP wouldn't  cover anything if I changed to another tuner since it was on the bike when they wrote the coverage agreement.

Your ESP will be void with the SESPT the same as any other tuner. The only thing ESP will cover anymore is street legal parts only and the SESPT is NOT legal. HD does have a street legal tuner call the SE Street tuner but it's just the same as there $150 download and does not allow for much of any tuning at all.

Wasn't told that by the dealer. Was very specific when I questioned them about the tuner before I bought the ESP. Since the tuner was installed before and the bike was used, was told that they would honor the agreement. They wont cover the tuner....I understand that, but other parts yes.
I guess when the time comes, if I need the ESP, we will see what they will cover.
