Okay, I've read a lot of posts regarding tuners and still am a bit confused.

I'm leaning toward the SEPRT. $450-$500 (with cable and software) seems pretty pricey for my objectives. The ONLY things I will do to my fat bob will be slip ons and high flow air.

MAYBE a full exhaust somewhere down the road, but I don't really see that happening. Not because I wouldn't like to, but really don't like LOUD and it seems all the pipes that I would consider are just that. LOUD.

So, is buying the pro tuner really worth it for me? Everything I've read and have been told (even by two dealers) says stay away from the street tuner.

It's obviously quite a bit cheaper. Will it do what I need?

 

We like the Power Vision, Mastertune TTS, and the SE Super Tuner. We recommend to dyno tune the bike w/ any mods because we know how much better the bike can perform w/ a good tune.

 

If all you're doing is an air cleaner you dont even need a tuner. I'm sure you'll get some good recommends from the guys here tho should you choose to add one anyway down the road...

 

With slip ons and a hi-flow a/c all you will need is an EFI tuner to make your fuel a little richer. With a hi-flow a/c and slip ons it will run a little lean with nothing. You can look HERE for some options that are more in your price range. Just look through and see which would be best for your year model or you can always give me a call here at the shop. I'm more than happy to help out with any questions you may have.

 

I see people debate on this a lot. But I picked up a used power commander III for $130 on eBay & installed it myself. Bike runs smoother with it after fiddling with the maps. I'm sure it's not comparable to a pro tune, but money well spent without a doubt.

 

If you know you are not going to do any more engine mods I would suggest seeing if you can find a competent dyno tuner in your area. Dynovision has a deal where you can pay a license fee and use the dyno operators tuner for around 150. Another 300 bucks for a dyno tune and you could be done for under 500 bucks. If you picked the right guy to do it you wouldn't need to buy a tuner and it would be dialed in to perfection. You ECM would be reflashed forever and you ride off into the sunset.

The key is finding the right place to do the dyno tune.

 

I have a Fat Bob too. First thing I did was a high-flow AC and SE slipons. At that time I also bought a SEPST and had it dyno-tuned. One thing leads to another and in time I upgraded my cams and had it re-dyno-tuned. Eventually I installed V&H Pro pipes and had another dyno-tune (see a pattern here?).

I'm planning on installing a Fuel-Moto 107 Big Bore kit next year and realized another dyno-tune would be necessary. So I decide to ditch the SEPST and bought a Dynojet Power Vision from Fuel-Moto so I wouldn't necessarily have to keep paying for time on the dyno. If you purchase the PV from Fuel-Moto they will pre-load it with a map for your specific configuration and they will provide you with new maps for free as you change your bike configuration. The PV also comes with an autotune feature that allows it to monitor your narrow-band O2 sensors and automatically make adjustments to the VE tables based on how your bike's engine, AC and pipes actually performs. I've taken the map I got from Fuel-Moto and gone through several autotune cycles and it works. The PV also comes with PC software to allow you to edit and make adjustments to maps (I've used the SW to edit my map to remove some deceleration popping). The unit even stores your original map and any other custom maps you create which allows you to switch back and forth (just pull over, shut off the bike and re-flash). You can even edit maps on the PV without requiring a PC.

The PV can be installed on your handle bars and used to display in real-time any signal your ECM monitors (Diagnostic codes, engine temp, battery voltage, RPM, intake pressure, etc, etc). The PV is about the same price as the SEPST but FAR more useful. As you can tell I'm very impressed with the PV.

 

Find out what tuner your dyno guy like to use and has the most experience with. TTS and SERT are real popular out here on the West Coast.

 

Call FuelMoto and get a Power Commander. Then when you change something all you have to do is email them for a new map.

 

I'm real happy with my Cobra Power Pro. I have added power and I'm getting better fuel economy. Never need a dyno tune. I can change what ever I want and it still works great.
