I'm looking for a source for the factory AFR settings for my new 2010 96 ci SG for various baselines +/-, i.e. idle, 2000, 3000, 4000, WOT. My first mod to the bike is fuel delivery as the 50 state approved setup runs way to lean and hot for me (old carb guy, 1st EFI). I'm curious to know what the factory considers safe to offer a 2 year warranty. Any insight is greatly appreciated!

 

Most of where you ride will be in closed loop. Depending where the closed loop bias is set it is around 14.6:1. Soon as you hit 90+ map (maybe 40% throttle or 4500 rpm) you will drop to maybe 13.2:1 or 13:1. These numbers are from after market tuning devices but I'll bet the factory is close if not a bit to the lean side of these numbers. You will probably want to use TTS to tune it.

 

Thanks! 14.6 seems lean to me which is evidenced by the heat and plug color I've seen so far. I've had good luck with Tmax with auto tune on my wife's 2007 96 ci Street Bob with simple stage one mods which targets 13.7 at mid range and mid 12's toward WOT. I'll probably go the with Tmax w/ AT on my new SG (once it's available) and pour some decent fuel to my new ride. Thanks again!

 

Why not retain all the features of your stock ecm? Buy a TTS and tune it yourself.

 

I've been successful tuning my wife's Tmax with auto tune and like the concept of the wide band O2 sensors along with the auto tune function that self adjusts for changing conditions. I need to learn more about the TTS product to see if it's capable of doing what I want to accomplish. Thanks for the input.
