He did ask about an auto tune thundermax. They are at a grand last time I checked.

 

I picked up the revolution performance ems from fuel moto at a great price. It is an auto tune setup with wide band 02 sensor's,the way it work's is you send them your ecm with all the info about your engine stock,stage 1,cam's,big bore,ect. They install a base map and it adjust's from there no dyno tune or anything,some on here don't like the thought of sending the ecm out but i've heard more good than bad about it.
Just put some mile's on yesterday for the first time with it and it ran great,plug's looked nice and tan. Just curious how it's gonna work when I do big bore and cam's!

 

I might as well add my .02 here as well. I tune just about every brand out there, it really comes down to what your bike has and what you plan on doing to it (if anything) in the future. First thing I would do is take what "Dr. Dyno" said and forget it. Any fuel injected HD that has a freer than stock flowing air cleaner need a fuel managment system, period. You can add pipes without one, but when you add an air cleaner you need it. The main "big brands" (PC's, SEPST, TTS, Thundermax, etc.) all work as advertised. I'd say your best bet would be to decide if you want to do the work yourself, or do you want to take it to a shop and have them do it? If you are going to depend on a dyno shop to tune your bike, I would suggest finding a shop that has a good reputation in your area and asking them what they are most comfortable using. Our shop sells and tunes them all, but we use the TTS Mastertune more than the others (about 10 to 1), but some of the others are just as capable. If you decide to go the PC route, like the others said, I don't think you can beat Fuel Moto for their customer service. Might even get free packet of Kool Aide LMAO.

 

i have aa thundermax and iam very happy with it if u buy a thundermax from a dealer yea there about grand. i bought mine from easternperformnace for $780.00 new and i have a 2011. buy what u want but i have used the power commander which went bad then the sest. then i bought the thundermax problem solved.

 

Another satisfied T-max user here. They do list at about a grand but, I paid the same a Rick.

 

I decided on the Powervision (bought from Fuelmoto).

My personal bias is that I want to use the bike's fuel management system - and not have a 3rd party plug in black box. I wanted to have the option of running in closed loop mode (one reason), and less chance of failure (2nd reason), and no problems installing (some of the add-on units require mods to existing plastic brackets etc).

The 3 that I am aware of that reprogram the stock ECM are the Powervision, SERT and TTS.

I chose Powervision for the following reasons:

a. Full access to program ECM
b. Can constantly re-tune and reload maps.
c. You can easily save and restore the stock map.
d. You can collect data for tuning by carrying this little control head - like a portable GPS. It is exactly the same concept as TTS - but TTS requires you to take a laptop for the ride.
e. You can tune using the stock narrow band sensors, or for a better tune, you can buy an auto-tune module and wide band sensors. Either options works just fine.
f. The little control head can display (programmable) any of a myriad of internal engine parameters and sensor data. So you get an extra technical display (when you want it) on the bike.
g. If you want to carry teh control head (you can mount on the handlebars if you want) - you can carry multiple maps and program the one you want (e.g. performance map, fuel economy map etc). It takes around 30 seconds to program the ECM from the Powervision head.


Now - I chose to buy from Fuelmoto for a few reasons, the most important of which is that they have dyno tuned maps that either match your config exactly or come very close. These act as the starting point before you do the fine tune using the stock o2 sensors (or wideband). I like this approach because I really don't want to dyno my bike. The dyno process is pretty stressful - they have to cover a huge array of load conditions and full RPM conditions on the bike. By buying a dyno duned starting map, I'm comfortable that the outlying regions of the map are good enough for me, and I can tune the normal riding portions of the map to refine it. This seemed to me to be the best of both worlds.

There isn't a "right answer" to the question "Which Tuner" - but the above was my thinking and fit into what I care about on my bike. Others may think differently and value different aspects.


Btw - price wise, they are all relatively close I think.

 

I like mine as well!
They say it will adjust up (or back) to 20% increase/decrease of the new build before you have to send the ECM back to them.

 

I have installed two of the Rev Performance EMS units on bikes in the last month. Both were somewhat mild builds (big bore 107 and 98) with torque style cams, 9.5 comp. This system worked extremely well on both scoots, one customer says it's the best his has ever run since the motor work was done almost two years ago.

 

Yep, they do retail for just under $1k, but I'm sure Fuel Moto sells them at a discount. I don't see them on their site, however.

 

Good post. I'm LMAO along with you.
