I've been using Power Commanders since my first FI Honda 929 back in 2000, so for the sake of this thread lets assume that I'm staying with PC.

Here's what I have: 2003 Electra Glide w/ PC 5, cams, pipe; 2007 Fatboy with PC3 USB, pipes, air filter; 2009 Dyna Superglide slip-ons no tuner.

I'm looking to get a Dynojet Autotuner to clean up the current tunes and retune for mods as they happen. I've seen two Autotune P/N listed for the Harleys. AT-100a and AT-100b.
Best as I can tell, the difference between the two are the size of the O2 sensors. Is that correct?
The O2 bungs are 18mm on the Dragos pipe on the Electra glide are 18mm, so I believe the 100B is the one that I need, correct?
Assuming that PC 5s are installed on the three bikes, the AT should work on all three with no issues, correct?

 

difference is 100b comes with weld in bungs for your 18mm sensors.

just the 100 is what you need.

as long as you have 18mm sensors on each, yep

 

Thank you Ultra, I'll get this thing on order soon so I can figger out how to use it.
