kinda up in the air on which way to go here bike is a 2010flhx can ya guys chime in with your exp also do i need to purchase the auto tune with the pcv-5 thnks.

 

if you are looking at pcv-5, look into the TTS www.mastertune.net

 

I prefer the SERT or TTS over the PC-v. You'd actually be getting the SEPST as it has replaced the SERT.

 

Neighbor has PCV with auto tune, its a relatively slow learner, runs OK eventually but expectations are great after spending all that cash and time installing it.. He will probably have to tweak the settings anyway. There are two modules to fit and protect from the elements. The auto tune system uses broad band sensors, compromised a bit in less than an ideal environment, to monitor all areas.

My TTS tuning kit put the bike near spot on, I think, within three 30 minute VTune sessions. Probably less work overall as I would have to spend as much time installing hardware. The TTS kit calibrates the ECU based on the stock O2 sensors over all of your normal driving conditions and then relies on a good guess out side those areas (like WOT).

My bike seems livelier than his and gets 2-3 better mpg. It may be just a difference in bikes as far as performance. I like the tool kit and control you get with TTS. The broadband sensor approach doesn't seem to buy you anything over the good guess approach (the sensors may not be accurate enough in the HD engine environment to make a difference). TTS costs much less and there is no added hardware to potentially fail.

Do some research, beware of fan boys and marketing gimmicks. There is no one right system for everyone.

 

so all i need is tts-mastertune no other pieces whats price on that item and who has best price thnks ohio

 

do i also need to buy the Serial cable and usb cable?????

 

The TTS kit will come with all that stuff. It's by far the best tuning software out their. That's my opinion and that's all folks

 

No you chose one of the other. The cable that runs to the ECM diagnostic port comes in the kit, the cable that connects to the computer is optional. You need to chose which one, and if you go USB like the most of us, just buy the TTS one as it works.

I think a couple forum sponsors, like Phat has them but you need to call for the best price. Last I checked they were running around $420 complete.

 

I think you must connect the TTS to a laptop while riding the bike to record the data so it can auto tune itself, the sepst uses a small recording device, size of a pack of smokes, to do this.
