roam Posted November 7, 2015 Share Posted November 7, 2015 Good morning, I was wondering what the procedure is for switching ECUs. Is it simply unplug old one and plug in new one? The instructions that came with the kit talk about giving the bike a tune after installing the new mufflers/ecu. Is that mandatory or can the bike be safely ridden without harming anything? I appreciate the assistance! Roam Link to comment Share on other sites More sharing options...
Admin Jaap Posted November 7, 2015 Share Posted November 7, 2015 It's plug and play, although a valve en TPS check beforehand is a good thing Link to comment Share on other sites More sharing options...
roam Posted November 7, 2015 Author Share Posted November 7, 2015 Thank you. Wanted to make sure the battery didn't need to be disconnected or honk the horn three times when swapping ECUs hah. Link to comment Share on other sites More sharing options...
sp838 Posted November 7, 2015 Share Posted November 7, 2015 where did you get the Ti exhaust and ECU kit? Link to comment Share on other sites More sharing options...
roam Posted November 7, 2015 Author Share Posted November 7, 2015 Harpers scored 6 kits that had been left in a warehouse somewhere and put them up for sale a couple weeks ago. Link to comment Share on other sites More sharing options...
Scud Posted November 7, 2015 Share Posted November 7, 2015 I always disconnect the battery before I swap out major or complex electrical things. This might be an unnecessary precaution, but it only takes a minute. The recommended TPS setting is a little different than stock. I talked to Curtis Harper. He said they were mislabeled in a Moto Guzzi warehouse - then somebody opened the boxes. Fun story - and not at all surprising, really. The Ti kit comes nicely packaged, eh? Except the paint on the hangers is terrible - mine don't even match. Link to comment Share on other sites More sharing options...
docc Posted November 7, 2015 Share Posted November 7, 2015 I had thought the ignition was to be off a minimum time (30 seconds?) before the ECU is disconnected, but I cannot now find that in the workshop manual. Otherwise, disconnect the negative battery terminals first and isolate them then being certain to avoid any contact of the positive side to the ECU case. And . . . a tune-up is always good!

roam Posted November 8, 2015 Author Share Posted November 8, 2015 I was also impressed with how well everything was packaged. I appreciate all the info! Link to comment Share on other sites More sharing options...
roam Posted November 16, 2015 Author Share Posted November 16, 2015 Well I got the kit installed over the weekend. New pipes sound awesome - nice rumble/roar but not obnoxious. Bike also seems to run smoother now as well. The right connecting pipe was a pita to get on the crossover. It did not want to slide all the way down. Left side went on no problem. Next were those damned muffler bands. Getting those on was a bit of a chore. Scud I appreciate your warning about isolating the positive cable from the ecu. I still managed to make some fireworks with how tight it is in there. Now for my question. The left muffler leaks a little bit of exhaust gas at the front where that riveted band is. Should this be a cause for concern? The bike seems to run well with no back firing. Link to comment Share on other sites More sharing options...
