I have just had excellent service from Steve Cole of TTS

Long story short.

Friend of mine had put a 120R motor into his 2011 103" Streetglide. Previously tuned by TTS since new , and again after 255 cams install

Original MTE lost in the death of a laptop. 120R motor came with a Supertuner that the engine installer tried to fit up to the bike.

( And no , they did not ask me first !)

NO-GO  was the outcome , so I was called in to load a TTS "120R" cal that I got from a CVO forum member the states

Bike ran really well , but now had a locked SEPST as well. $525 of wasted money really

Thru the CVO forums Steve Cole of TTS sent me an E-Unlock.MTE file that I loaded which then allowed the SEPST to flash the ECM , which we then saved as an MTE using the "save" cycle on the TTS. We "saved" that "Stock.MTE" EVERY *UCKING WHERE !

Then reloaded the 120R TTS cal using TTS and the bike is all good with max mumbo AND good fuel consumption

Main moral(s) of the story ?

Save your "Stock.MTE" calibration in more than one place and use TTS as a first choice !

Thanks again to Steve Cole from TTS for really coming thru' for me and my mate

Lost my stock MTE calibration when my wife decided to clear everything of an old lap top and give it to someone else

but in saying that I have never need to revert back to it and I just always thought that if I ever needed to that
1 - I could use the original MTE for a softy the same year as mine that I have
2 - Steve Cole would come to the rescue if I need to have one

Yes mate , I used to think that any "Stock.MTE" would do for " going back to stock" but it's a no-go

The original VIN is embedded in the stock tune and it would appear that we can't recreate it ( I did try !)

I have reflashed to stock my 2008 CVO Springer many times , to flit between "older" original SERT MT6 calibrations and " younger" TTS MT7 cals

I had saved that MTE cal from my CVO Springer more than one place at the time , including onto USB sticks , so no worries there

I had to send TTS a " saved" cal from my mate's 2011 Streetglide and Steve Cole had the necessary software access to create an E-Unlock.MTE for me.

We only really "needed to revert" as you say because another guy tried multiple times to reflash it with a new SEPST tuner that he managed to "marry" to the ECM.

Waste of a new $525 SEPST as it happens , as he was on TTS anyways. Like I said , they didn' t ask me first !

Thanks guys, but it all in a days work. We do the best we can with whatever is tossed our way.
