Spoke to a Local Harley Mechanic today and he said they don't ever have updates to the ecm.
Who's on first? So if I understand right, when the 15's came out the non-volatile hardware was obsolete, and since you can't replace the hardware, your required to have the dealer reinstall the left thingy- majig but the moco hasn't sent the right turbo-master yet. So after calling the dealer and getting a free cup of joe you pay your $29.95 and leave with a free map of Austin. Did I get that right?
God I'm as funny as this thread is confusing and amusing! Good thing I already have a map, cup of coffee, and a bad memory.

Either your mechanic or the 3 of us that have reported our stock ECM's were updated all have mechanics that don't know what they are talking about. It wasn't an infotainment system update. I had already updated to 1.18.2. They pluged the digital technician into a port under the left side cover. I watched the progress bar move slowly across the screen for several minutes while it updated. The stock flash on the ECM has nothing to do with what a PV or SEPST can and can't do.

Really not worth all this. If your dealership updates your ecm, so be it. Ours don't and the Service Manager said something about the same deal of having to do the updates in 2008, but he was going from memory so it may have been 07 models. He said as far as programming they can reload the stock tune and it will do as was described. Plays heck with the guys that flash tune.

Kinda reminds me of the Clutch master cylinder recall from September 8th. After it was reported on here some dealers claimed they didn't know anything about it untill a couple weeks later. Then some kept claiming they didn't get any parts. All I intended to do with my post when I mentioned the ECM update on my 10/4/14 thread https://www.hdforums.com/forum/new-r...k-service.html and all I'm sure the OP of this thread was trying to do was make others aware there is an ECM update out there. I didn't ask my dealer to do it. I just saw them plug into the port under the left side cover and download something to the bike during my 10K service. When I asked what they downloaded they told me about the ECM update. If you don't want to believe they can and do update the firmware/software on the ECM that's your choice. Please don't shoot the messenger.

Not sure where you got your info that the stock flash has nothing to do with the PV or SEPST. If you reflash the ECM any tune on it is wiped out and the new flash takes its place. I guess it could be possible for the digi tech to save the current tune and add the updates to it and reload. Could you tell any difference after they did your update?

I am not trying to slay the messenger. Does your dealership do any dyno work or sell tuners? I do all the map building and tuning for the SEPST, PV, PCV, TTS for our dealership and if they start updating the ecm on bikes as a routine in service, they are going to find someone else to do the maps as it will wipe them out. They don't have a dyno, but those that do will loose their Dyno tunes also. I did have a service tech unhook the autotune module on PCV as it plugs into the Data connector. I think he just forgot to hook it back up. They had installed it anyway, so I doubt any intentions to disrupt the PCV.

I have only noticed one difference in the bike since the update. I have had an app on my phone since the end of June that I log every gas fill up on. Prior to the update I never got less than 40mpg unless I was pulling my trailer. With the trailer it drops down to around 38. I have filed up 6 times since the update, the best I have gotten was 39.85 and as low as 33.69. None of those was pulling the trailer. The weather has been cooler, that might explain part of the drop in MPG.
I read in another thread about custom tunes and warranties that if you have flashed a non harley tune on your bike it sets some flag in the ECM. Don't know if that's true or not, but if it is would the digital tech not do the update if it sees a custom tune?
