Right now I have a stock bike with open a/c. Want to gut my cat and get a tuner. Then go from there.

I'm assuming ThunderMax is a direct bolt in replacement ecm including O2's. Which will go in the stock location of factory O2's.

Then it just auto tunes the bike from there? So any add ons I do in the future, it would just correct on its own?

If true, what is the air/fuel ratio it is trying to achieve?

Better than power vision.

Any thing I am missing would be greatly appreciated!

I'm not a tinkerer. Would prefer something that is just plug in and go to town.

 

My 06 has cams, full duals and came with a thundermax. Overall I like it and runs good but at times it has a high idle on start up, dies on first start and when cracking the throttle will sometime falter and either spit out the t-body or die. I do a reset and alls OK for a few thousand and then its seems to fall back to the previous issues. I wasn't involved in what MAP was installed or the tuning so I need to get it to someone knowledgeable. I think there may be better options from my experience for what its worth,

 

If you go to ThunderMax's website, they say their the best! Lol.....

Like most, I hate to hear sad stories. But do appreciate that input.

I put a open a/c on my bike and lost 3/4 mpg. Just a guess, but I bet it's close. Probably more!

 

I'm a plug and play guy so glitches **** me off. The issues I have are small but with mods you get imperfect stuff. I traded my dyna for this bike and he installed a thundermax on it so he loves it.

 

'Don't know what bike you have?


The '10 and later HDs have narrow band O2s, the tmax comes with widebands, requiring a different pipe or welding bungs in your pipe.


'Recommend you do more research and try and wade through the marketing hype / BS. The tmax is not install and forget, nothing else really is either, except a Tuner / Dyno Tune, but then when further (engine) upgrades are done, more $$ to Dyno...


The Powervision is a good unit. FuelMoto is known for their tech support / customer service.

 

I've had Tmax on 5 bikes, EG Classic, Ultra and Ultra Limited, both the 96 and 103. I do Stage 1: AC, Headers and mufflers. From Tmax website I find the map that matches my components and download it to the TMAX. The O2 sensors are wide band and go up close to the cyl head, they do not use the factory bungs so if you are decatting the pipe get some 18mm bungs for the wide band O2 sensors and plugs for the 12mm bungs. Auto tune is simple and you interface with a lap top which is no big deal. You also do firmware and software updates with the PC.


My bikes ran great with the tuner and I do recommend them. I just bought a couple new bikes and this time around I'm trying the Dynojet PV2. So far I like it.
Good Luck

 

If you are computer literate and like to to tinker with your bike buy the ThunderMax. Your bike will run great and you will never have to pay for a dyno. If you are like me you will enjoy tweaking tune once every 1000 miles or so.

If not, I would recommend a Power Vision from Fuel Moto. Why? Because they will supply customers with new maps for life. The PV can be a very simple install the tune and forget about it device.

 

I have a T-Max in two bikes. I like the fact that I can make a change to a bike and not rely on anyone else to tune my bike.

They use wide band O2 sensors that require 18mm bungs welded in close to the head. I think within about 4" is optimal.

It is a replacement ECM..

You download the software to a laptop and plug into the T-max with the supplied USB cable.

They have many base maps in the software. You choose the map closest to your setup. Throttle body size and cam duration are the most important factors to consider. The unit will auto tune over time to any map but it might not run well at first and will require more auto maps to achieve the optimal tune.

Once you have loaded the closest map into the T-max, ride it. After a couple rides, connect to it with your lap top and run the auto tune analyzer. It will tell you wether or not to run auto map. What happens is as you ride it adjusts fuel points in the base map based on real time feedback from the wide band O2 sensors. It will only auto tune out to a 15% offset from the base map. If several points have reached the 15% offset, the auto tune analyzer will recommend you run auto map. Auto map will use the auto tuned points to create a new base map so that next time you ride it can auto tune it's self closer to the optimal tune. The closer your base map selection is to your bikes configuration, the less times you will have to run auto map.

I probably confused you but it's easier to use than it sounds if you have basic computer skills.

I recently did a 98" big bore with Woods 555 cams on my wife 06 Ultra. I downloaded the closest map I could find. The first ride I could tell it ran better at the end of the ride. It's got close to 500 miles on it now and I've ran auto map 3 times. It's running great. Some time after the 500 mile oil change when I put synthetic back in, I want to have it ran on a dyno to see what the numbers are compared to before the build.

 

Don't limit yourself.

Tmax is a good unit, but high on the $$ scale.

A lot of aftermarket headpipes come with both 12mm and 18mm bungs, and plugs for the unused ones.

PV2 or FP3 from FuelMoto are no harder to use, and will auto tune with your stock O2 sensors, thus, no getting bungs welded.

IIRC FP3 is around $300, and the PV2 is $499.

 

I had nothing but problems with my thunder max. It killed four battery's before they could get there act together. I would look at another fuel management system.
