TTS Master Tune ?
Also, TTS were the original designers I guess you could say of the SERT. I believe all the other functions that you can use with TTS couldn't be folded into the SERT. Probably due to HD direction.
TTS is not an "autotune" system and requires a bit of learing and some understanding of the relationships of timing and fuel. TTS can you get to about 80 - 90 percent right, same if you run SERT but with SERT you would need another diagnostic tool.
There are autotune systems out there, but they too are not truly autotune, you still need to make tweaks to maps. Nothing beats a dyno but you can get close.
The TTS has some really nice capabilities, and I am happy with it so far, having switched from the DTT TCFI IID system.
If I understand correctly, this TTS system will tune the bike with your help using the 02 censors . Then the trick comes when you learn how to twick the map. Am I reading this right ?

And.......... I just bought TTS and did this datalogging and tuning. It's easier than it appears. All it take is a good 'gotcha' moment, and it all falls together.

I do NOT see why a decent tuner can't do TTS, either. TTS is an outgrowth of SERT. SAME tuner as SERT, actually the company that made the SERT now makes the TTS, but TTS has upgraded capacities. SAME VE tables, and AFR tables, etc.

ALl that being said, and I REALLY like my TTS.
For simple Stage 1 build, a PCV with auto tune should be good. The canned map question has been beat to death here, but they DO make your bike run OK. But......... one needs to think ahead. If a cam or anything whatsoever beyond a Stage 1 is even remotely in your future, you need to think hard about a TTS. IMHO.

Read THIS whole thread, then you will know if u want a TTS
