This thread has been interesting. Thanks to all for the discussion.

I have asked this question before in the forum and am struggling what to do now since Christmas is approaching and I might make a decision...

The bike:
I have a 2005 Night Train with SE intake and slip-ons and the Stage 1 flash from a dealership. No plans for any engine modifications. Would like to change the intake & exhaust.

The budget:
It's tight. What I would like to do and what I can afford are two different things. I would like the most bang for the buck with an eye for the future.

The choices:
1. PV-1 only. Not interested in less BTW.
2. #1 with the AT (w/ 18mm WB O2 sensors).
3. #2 with Bassani Road Rage pipes.

I really want #3 but will be hard to justify the $s all at once. I think I could pull off #2 and install bungs in the current head pipes or just shelve the AT for the time being (but still buy it because it's cheaper that way overall) until I get the exhaust.

What is the ultimate value of the AT relative to the PV-1 open-loop with the minor changes that have been made to the bike?

For what it is worth, as an engineer, I am intrigued by the tinkering aspect of the AT.

Thoughts? Thanks.

Personally. I would get the base PV setup planning on getting the Target Tune later as money comes around. For now simply understand and deal with the limits of a narrow band O2 tune.

The guys at www.Fuelmotousa.com can help you dial it right in.

Thanks.

Note that AutoTune Basic is not applicable to a PV-1 on a 2005 Softail (no O2 sensors) and Target Tune is not available on a PV-1 for a 2005 (IIRC). Does that change your opinion?

I would talk to Jamie at FuelMoto to figure out your options. You really can't tune a bike at home without 02 sensors. At least I have never found a reasonable way to do it.

Yup, narrow band 02s are better than none when it comes to home brew tunes.

I guess the only real way you could do tune without 02s is to stick a sniffer up the tail pipe and see what comes out.
This is an area where a dyno really shines.
