Are you asking can you take the ECM you removed and replaced with the Tmax and install it in another bike so they can use the Screamin Eagle tuner?
I had a similar situation with a ECM from a 2009 EGC with the TTS tuner. I called a well known tuner in Florida who is very well versed in TTS and HD and he said yes. You had to make sure the bike you were going to install it on had the same set up as the one you were replacing like FI or carb, Throttle by wire ect.
Then last year someone asked about replacing a ECM on a Rushmore and a Sponsor said they are now married to the serial number and you would need to take it to a dealership to have it programmed.
So it might be wise to call the HD Tech line and see what they say: 1-800- 258-2464
Good Luck

You mentioned light years ahead of the screaming eagle tuner, can you explain? i know when I had my bike tuned after I installed the 48 cams, the tuner said he like the screaming eagle, he tunes a lot. I ended up with 96 hp with a 96" engine, which I contribute to Wolfgang (the tuner). Are we talking Jettsons vs Flintstones? syncing with your I phone? I've heard of the Mastertune before but thought it was a module to link to the ECM.

What does this have to do with the Thunder Max?
You save $100 but still have a piggyback system, think I'd rather got with the T-max.

I've never had a Screamin Eagle Tuner. I have had 2 TTS Master Tune, 5 Thundermax, and now we have 2 Power Vision and though the others worked well I recommend the Power Vision.
All of my bikes have been stage one, AC, Headers and Mufflers so take that into consideration. I like something that is easy to install, simple to auto tune and works well for my set up and the PV Does that.
I'm not a tuner and I tried to learn what I could from any sources I could find so if I misrepresent something here I hope someone will correct me. But in a very small nut shell:
The T-max to some is deemed old fashioned because it is a Alpha N type tuner. This means it uses Alpha, the angle of the throttle plate and N rpm to determine how much fuel to deliver to each cylinder.
The PV is a Speed Density tuner, it uses Manifold Pressure and RPM along with the Volumetric Efficiency tables to deliver the correct amount of fuel.
This is a link to the TTS Manual and gives a basic over view of what a tuner is doing to make your bike run at it's best.

Thunder-Max/SE problems
Has any one had any issues when changing from the SE to the Thunder-Max and/or did you remove the SE before putting in the TM? Thanks.

As always, the same BS from the Tmax guys feuding with the Flash tuner guys.
A couple facts to consider:
Tmax is not supported (worked on) by the MOCO or its dealers. Replacing the entire engine management system with an aftermarket system voids warranty.
Tmax has no combustion detonation (ping) protection (knock retard) like the OEM syste.
It is for the above mentioned reasons I do not reccomend Tmax for any bike that will be leaving his/her Tmax servicing shop area in case of diagnostic needs or repairs when things don’t run as expected.
