Just talked to the service manager of my local HD dealership. I have had good luck with them as opposed to the dealership where I bought my 2011 Fatboy so I respect their opinion. He recommended the SERT tuner for my bike. After reading all the threads about the many tuners availabe I really haven't seen much about the SERT. How is it??

 

The guys that I know that have it like it. The only down side is that it is married to the bike and can not be transferred to another bike. Also since it is basically a download to your ecm there are no additional modules or wires for you to install. I personally preferred the power commander but that's me. I think you just have to figure out what you want to accomplish and then find what works and fits in your budget. Happy hunting!

 

If I had to do it over again I'd go with Master Tune TTS, that's what my dyno tuner prefers.

Here is the differences between the TTS and Power Commander..

Power Commander is a piggy back device. It intercepts the ECM outputs and modifies them to send them to the injectors and coils to provide the proper fuel and spark timing.

Pros: It can be used on multiple bikes. So if you change bikes later, you may be able to use the same power commander. (There is a limit. For example the PCIII can't be used on 2009's. They changed to PCV for that model year.) It can be resold and used on any similar bike.
Cons: It's a piggy back device. It needs to do multiple calculations upon receiving the information and transmitting it down the line. It may only take a fraction of a second, but there is a delay. The connectors have proven to be problematic for accumulating water in some applications rendering the bike un-ride able. If the PC takes a dump, then you risk riding a bike with bad timing or fuel delivery and can harm the motor.

The ECM Re-Programmers: SEPST and Master Tune is an interface device. It allows you to re-program the ECM with things like Startup enrichment, acceleration enrichment, deceleration enleanment, as well as idle and redline control.

The Master Tune makes available a lot more tables that you may or may not want to interface with, depending on how deep you want to go into tuning. Master Tune allows you to change wheel and tire sizes and CALIBRATE your SPEEDO accordingly, by changing the Speed Sensor calibration. The Master Tune also has the abilty to make a CUSTOM MAP based only on the existing O2 sensors that come on 2006 and later V-Twin models.

Pros: It's not a piggy back device. It has ZERO delay. It minimizes the connectors, so it's water intrusion is the same as a stock bike. You maintain the use of your closed loop EFI system to optimize your fuel mileage. (on bikes with 02 sensors) and you maintain use of the ion anti-knock sensors. (A HUGE BONUS for those who tour extensively and are forced to use "Less than premium gas" on occasion.)
Cons: It mates to your ECM so you can only use it on ONE of your bikes. (The Master Tune can be used on 2 bikes, but it mates to them and can not be used on any other bikes.) It should be tuned on a DYNO for best results.

If you go the HD route, then you want the SEPST not the SERT. The SEPST is a good tuner.

 

I got the SERT for christmas, it is pretty cool, it will also show any trouble codes stored in the computer, and it will also show real time data of what the ecm is doing (timing, air temp, reading from all sensors)

 

SERST is the new name for a SERT. I use one and you can do the same with both TTS and SERST. they are highly adjustable and yes married to the bike which is not a bad thing either. Tes they should be set on a dyno for best results but both can selftune and if you are knowlageable you can do it your self by useing the o2 sensors that are already in the bike. Both are good systems

 

Thanks for the information!

 

The SESPT (Street Performance Tuner Kit) is calibrated to meet EPA regulations. HD also offers the SE Super Tuner Pro, which replaced the SERT. You didn't mention any performance modifications that you've made or are considering. Typically, people tune when they add a high-flow air filter and pipes, change cams, etc.

 

Modifications are Rush Crossover pipes and stage 1 air cleaner. Cams and head work may come later.

 

Use what ever the tuner recommends and is most familiar with. If you have a preference, then you need to find a tuner that is very experienced with that device.
